The difference between ordinary wall hung boiler and condensing wall hung boiler

1.The difference between condensing wall-hung boiler and ordinary wall-hung boiler - comparison of energy saving:

Ordinary wall-hung boiler: In the traditional boiler, the exhaust gas temperature is generally 160 250, or even higher, so that the water produced during fuel combustion is in a superheated state of water vapor in the flue gas, and the thermal efficiency of the traditional boiler can only reach 85% 91% with the flue gas from the chimney. Condensing wall-hung boiler:

The condensing gas boiler reduces the exhaust gas temperature to 50 70, fully improves the sensible heat in the flue gas and the condensation latent heat of water vapor, and the thermal efficiency can reach up to 109%, which is very energy-saving.

2.The difference between condensing wall-hung boiler and ordinary wall-hung boiler - service life comparison:

Ordinary wall-hung boiler: the traditional wall-hung boiler due to various factors, resulting in the product service life can not meet the design requirements (generally 15 years), some European pure imported wall-hung boiler service life is generally 5 to 8 years, domestic miscellaneous machine is generally 3 to 6 years, condensing wall-hung boiler: condensing wall-hung boiler service life (about 25 years) due to its revolutionary product working mode, the life will be significantly ahead of the traditional wall-hung boiler.

First of all, it is necessary to look at the energy efficiency identification of the wall-hung boiler, generally the ordinary wall-hung boiler is the second-level energy consumption, and the condensing wall-hung boiler is the first-level energy consumption.

Secondly, looking at the internal structure, the condensing wall-hung boiler is divided into full premixed condensing machine and secondary condensing wall-hung boiler, the internal sealing of the full premixed condensing wall-hung boiler is relatively good, the integrity is good, and the secondary condensing wall-hung boiler is the first temperature of the smoke tube, which improves the thermal efficiency. Therefore, the distinction should not only be seen from the outside, but also carefully discerned from the inside.

Ordinary wall-hung boiler is atmospheric combustion, that is, the gas is completely burned in the air, the equipped fan is an induced draft fan, the state of the combustion chamber is negative pressure combustion, and the air and gas enter the combustion chamber by negative pressure.

Generally, the excess air coefficient of the wall-hung furnace with atmospheric combustion mode is simplified between the fan configuration, and the excess air remaining from combustion is discharged while taking away a large amount of heat.

The excess air coefficient of the fan configuration of the full premixed condensing wall-hung boiler is generally between, and the amount of air configured is greatly reduced when the same gas is burned, which also reduces the loss of the effective voltain rate caused by the exhaust smoke.

1.Energy and gas saving.

The condensing wall-hung boiler uses advanced "condensation technology" to reduce the exhaust gas temperature to below 60, which not only absorbs a large amount of sensible heat in the flue gas, but also in a liquid form at low temperature, and absorbs the latent heat of the flue gas at the same time, so that there is no excess air and can be burned completely. Two factors make the thermal efficiency up to 107, while the thermal efficiency of an ordinary boiler can only reach 90.

2.Environmentally friendly and low-carbon.

Ordinary wall-hung boiler adopts atmospheric combustion, the air contains about 80% nitrogen and 20% oxygen, nitrogen reacts with oxygen to form nitrogen oxides, and nitrogen oxide emissions are an important cause of air pollution. The condensing wall-hung boiler proportionally proportions air and gas, which reduces the generation of missing nitrogen oxides.

3.Save money.

Taking a heating season as an example, according to the calculation of 80 square meters of heating space per household, the condensing wall-hung boiler can save more than 10% energy compared with the ordinary wall-hung boiler. The thermal efficiency of the small squirrel condensing wall-hung boiler is as high as 107%, which is about 15% more energy-saving than the conventional wall-hung boiler.

How to carry the ordinary wall-hung boiler and the condensation elimination key wall-hung argument bridge destroyer furnace.

Pukuxintong wall-hung boiler is an atmospheric burning potato, that is, the gas is completely burned in the air, the fan is equipped with an induced draft fan, the state of the combustion chamber is negative pressure combustion, and the air and gas enter the combustion chamber by negative pressure. Usually, the excess air coefficient of the wall-hung boiler with atmospheric combustion mode is between the excess air coefficients of the fan configuration, and the excess air remaining from combustion is discharged while taking away a large amount of heat. The excess air coefficient of the fan configuration of the full premixed condensing wall-hung boiler is generally between, and the amount of air configured is greatly reduced when the same gas is burned, which also reduces the efficiency loss caused by smoke exhaust.

1.Energy-saving and gas-saving The condensing wall-hung boiler uses the advanced "condensation technology to slip the loser", so that the exhaust gas temperature is reduced to below 60, which not only absorbs a large amount of flue gas.

Which is better, ordinary wall-hung boiler and condensing wall-hung boiler, of course, is better for condensing furnace, ordinary heating furnace is a second-level energy efficiency, and condensing furnace is a first-class energy efficiency. The condensing furnace reduces the exhaust gas temperature to 50-70 for reuse through the sensible heat and water vapor in the latent heat** flue gas, so as to be more energy-saving and environmentally friendly.

Due to the high temperature**, the 316-i stainless steel used in the main exchanger of the Viessmann condensing furnace is military grade, which is more corrosion-resistant than the exchanger of ordinary wall-hung furnaces. In addition to energy saving and environmental protection, the condensing furnace will heat up faster than ordinary wall-hung boilers and have a longer service life.

Summary. Hello! Dear, I'm glad to answer for you!

Hello, ordinary wall-hung boilers and condensing wall-hung boilers, condensing wall-hung boilers are better. The condensing wall-hung boiler is an upgraded version of the ordinary furnace, simply put, the condensing furnace is more energy-saving and environmentally friendly, and the improvement of thermal efficiency also helps to save the use of gas.

Hello! Dear, I'm glad to answer for you! Hello, ordinary wall-hung boilers and condensing wall-hung boilers, condensing wall-hung boilers are better.

The condensing wall-hung boiler is an upgraded version of the ordinary furnace, simply put, the condensing furnace is more high-closed, energy-saving and environmentally friendly, and the improvement of thermal efficiency also helps to save the amount of gas to split the limbs.

Condensing technology is a scientific and technological means to improve thermal efficiency, through the use of condensation technology, the efficiency of gas wall-hung boiler is greatly improved, which also means that energy consumption is reduced; More importantly, an energy-saving and environmentally friendly gas wall-hung boiler plays an irreplaceable role in improving the user's living environment and improving the quality of life. The biggest feature of the condensing wall-hung boiler is that it relies on the condensing technology to achieve excellent energy-saving effect. The principle of condensation refers to the release of heat in the process of condensation of flue gas with high distressed temperature, and the condensation technology is to fully collect this heat to increase the heating heat.

Through the condensation of flue gas, the energy in the exhaust gas is realized, and the net calorific value is increased, so as to achieve a thermal efficiency of 107%, which not only reduces the amount of gas, but also greatly saves energy consumption; According to the user's heating needs, the temperature sensing device monitors the inlet and return water temperature, indoor temperature and indoor and outdoor temperature difference, and intelligently selects the most energy-saving and comfortable heating power and heating temperature, so that the machine can operate efficiently with low consumption and save energy consumption by up to 15% compared with ordinary wall-hung boilers. The condensing gas wall-hung boiler fully absorbs the sensible heat in the flue gas and the latent heat of water vapor through two heat exchangers. The calorific value of ignition refers to the heat emitted by the complete combustion of 1 nm3 of gas.

The calorific value is divided into high calorific value and low calorific value, and the high calorific value refers to the heat released when the flue gas is cooled to the original temperature after the 1nm3 gas is completely burned, and the water vapor in it is discharged in a condensate state; Low calorific value means that after the 1nm3 gas is completely combusted, all the flue gas is cooled to the original temperature, and the water vapor in it is still the heat emitted when it is discharged in the vapor state. It can be seen that the difference between the high calorific value and the low calorific value of gas is the latent heat of vaporization of water vapor.

1. The life span is different:

Ordinary wall-hung boiler: due to various factors, the service life of the traditional wall-hung boiler can not meet the design requirements (generally 15 years), the service life of some pure imported wall-hung boilers in Europe is generally 5 to 8 years, and the domestic miscellaneous machine is generally 3 to 6 years, condensing wall-hung boilers.

The service life of the condensing wall-hung boiler (about 25 years) is bound to be significantly higher than the traditional wall-hung boiler due to its revolutionary product working mode.

2. Comparison of energy saving:

Ordinary wall-hung boiler: In the traditional boiler, the exhaust gas temperature is generally 160 250, or even higher, so that the water produced during fuel combustion is in a superheated state of water vapor in the flue gas, and the thermal efficiency of the traditional boiler can only reach 85% 91% with the flue gas from the chimney.

Condensing wall-hung boiler: The condensing gas boiler reduces the exhaust gas temperature to 50 70, which fully improves the sensible heat in the flue gas and the condensation latent heat of water vapor, and the thermal efficiency can reach up to 109%, which is very energy-saving.

3. The combustion technology is different

The condensing wall-hung boiler is a precise mixture of air and natural gas in proportion, 360-degree fully sealed combustion, high efficiency, and small sewage discharge index.

Traditional wall-hung boilers are not able to achieve complete mixed combustion. Large heat loss.

Wall-hung boiler.

The thermal efficiency is high, up to 109%; The service life is more than 20 years, which is more durable than ordinary wall-hung boilers. In addition, condensing wall-hung boilers.

It also has the characteristics of energy saving and environmental protection, which further brings convenience to users.

Answer 1: The condensing wall-hung boiler uses a very high-tech energy-saving technology in the current wall-hung boiler industry - condensing technology. The condensing wall-hung boiler can not only make the best use of the remaining heat in the flue gas, but also reduce the exhaust gas temperature to about 40 degrees. 2. The condensing wall-hung boiler can also fully absorb the latent heat of water vapor in the flue gas, and make full use of it at the same time, so as to improve the thermal efficiency of the wall-hung boiler, and the thermal efficiency can be increased to 109% at most.

The thermal efficiency of ordinary wall-hung boilers is generally only about 90%, which will be about 25% higher. 3. The combustion chamber of the condensing wall-hung boiler is generally made of stainless steel or silicon-aluminum alloy material, which has good acid resistance and corrosion resistance. In addition, there is generally no temperature limit on the return water temperature of the condensing wall-hung boiler, so the service life of the condensing wall-hung boiler is relatively long, and the maximum can reach more than 20 years.

4. Because the condensing wall-hung boiler can be burned very completely, the condensing wall-hung boiler has the advantages of low energy consumption and high environmental performance. Most of the condensing wall-hung boilers are wide frequency conversion, which can automatically adjust the load, the temperature control capacity is very stable, and the water output is very comfortable. 5. Because the materials used in the condensing wall-hung boiler are corrosion-resistant, the condensing wall-hung boiler can be widely used in most heating systems, such as:

Ask what does wide-range inverter mean.

The answer is that there is a wide range of adjustments. Frequency conversion technology is actually automatic adjustment, when the wall-hung boiler reaches the indoor set temperature, it will continue to compensate for the heat loss according to the temperature detection, if the frequency conversion is relatively small, the indoor and outdoor temperature change will be relatively large, and the temperature can not be adjusted under the condition of maintaining a constant temperature, it is likely that the heating power is greater than the loss speed, resulting in repeated switching, which not only affects the life and energy consumption, but also the constant temperature effect must not be good, the temperature fluctuation will be relatively large, and the 1:10 frequency conversion ratio represents every 10% The amplitude of adjusting the combustion power and controlling the indoor temperature is 1:

The inverter ratio of 3 is much better.

1. The combustion technology is different

Ordinary wall-hung boiler: gas air cannot always achieve the mixing ratio of complete combustion, so the heat loss carried away by the flue gas is large, the pollution emission index is high, and the thermal efficiency is lower under partial load than under full load condition.

Condensing wall-hung boiler: the waste heat in the flue gas is utilized, and the combustion mode is adjusted in the proportion of full premix, and the exhaust gas temperature can be reduced to about 40.

2. The service life is different

Ordinary wall-hung boiler: Due to the design of key parts such as heat exchanger and combustion chamber, coupled with water quality and other problems, the service life of the product can theoretically reach 15 years.

Condensing wall-hung boiler: The service life is much greater than that of the traditional wall-hung boiler because of its advanced technology, which is about 25 years in theory.

3. Different energy-saving efficiency:

Ordinary wall-hung furnace: the thermal efficiency can only reach 85% 91%, because the ordinary wall-hung furnace exhaust flue gas temperature is high, and the water generated during fuel combustion is in the state of water vapor in the flue gas, which is discharged from the exhaust pipe with the flue gas and loses the thermal efficiency.

Condensing wall-hung boiler: the thermal efficiency is greater than 91%, up to 109%. The new condensing technology can automatically control the exhaust gas temperature during the combustion process, and the heat in the flue gas is reduced to 50 70, which is very energy-saving.

4. Different scale treatments:

Ordinary wall-hung boiler: In order to improve the heat exchange efficiency, small size heat exchangers are mostly used, and the pipe thickness is low. However, the domestic water quality has high hardness and long service time, and the pipeline system is easy to form scale and damage the equipment.

Condensing wall-hung boiler: With a new mixed heat combustion and large pipeline waterway system, compared with ordinary wall-hung boiler, there is generally no need to worry about scale.

5. Different:

The condensing wall-hung boiler has new technology and high cost, so its machine cost will be higher than that of ordinary wall-hung boiler**.

Condensing wall-hung boiler and ordinary wall-hung boiler are two different types of hot water heating equipment, and they have some differences in working principle and efficiency.

1. Working principle: The condensing wall-hung boiler uses the combustion of gas or oil to generate heat energy, and then transmits the heat energy to the heating system or hot water system through the heat exchanger. At the same time, the condensing wall-hung boiler also uses the water vapor in the flue gas to release latent heat to improve thermal efficiency.

Ordinary wall-hung boilers only use the heat energy generated by combustion for heating.

2. Thermal efficiency: The thermal efficiency of the condensing wall-hung boiler is usually higher than that of the ordinary wall-hung boiler. Because the condensing wall-hung boiler can use the latent heat released by the water vapor in the flue gas, its thermal efficiency can reach more than 90%, which helps to save energy and reduce energy costs.

The thermal efficiency of ordinary wall-hung boilers is usually around 80%.

3. Emission and environmental protection: Because the condensing wall-hung boiler can make full use of the heat energy generated by combustion, and reduce the consumption of fuel by reducing the leakage of the hood, the exhaust gas emitted by it is relatively small, and the impact on the environment is small. Ordinary wall-hung boilers have relatively more emissions.
