What does the condenser of a gas steam boiler do

The condenser is actually a kind of flue gas waste heat exchanger, which is the same as the economizer at the tail of the coal-fired boiler. The exhaust gas temperature at the tail of the boiler is very high, and the flue gas from the boiler is discharged through the condenser after using this equipment, which heats the water in the condenser, which can increase the temperature of the boiler feed water, reduce the exhaust gas temperature, and improve the purpose of saving fuel.

Condensing gas boiler, as the name suggests, is a condensing gas boiler, and now the condensing gas boiler can be divided into condensing household gas boiler and condensing commercial gas boiler, and the product is also different from two series of condensing floor boiler and condensing wall-hung boiler.

The working principle of the condensing gas boiler: through a certain device, the energy in the hot smoke discharged from the boiler after combustion, the exhaust gas temperature is only about 60 degrees Celsius, so that the thermal efficiency is about 10% higher, which naturally saves about 10% of the gas of the beater, and at the same time, in the energy process, it can also reduce the harmful emissions of harmful gases and reduce environmental pollution.

The working form of the condenser and the evaporator is different, the condenser is to cool the medium and liquefy, and release heat externally; The evaporator is the medium absorbs heat and gasifies and absorbs external heat, that is, the refrigerant changes from gaseous state to liquid state, which is a condensation and exothermic process, and its internal pressure is generally very high; The strain-off refrigerant of the evaporator changes from liquid to gaseous state, which is a process of steaming and sensitively absorbing heat, and its internal pressure is generally low.

Introduction: 1. The condenser is a device that can condense gaseous substances into a liquid state, and generally uses cooling to condense the substances. It can transfer the heat in the tube to the air near the tube in a very fast way, turning the gas or vapor into a liquid.

Condensers are mainly divided into two types: steam condensers and boiler condensers, which are widely used in power plants, refrigeration plants, petrochemical industries and other industries!

2. The evaporator is a very important part of the four major parts of refrigeration, and it is also a kind of wall heat exchange equipment. The low-temperature condensed "liquid" body passes through the evaporator to exchange heat with the outside air, and the "gasification" absorbs heat to achieve the effect of refrigeration. The evaporator is divided into three types according to the operating pressure: atmospheric pressure, pressurization and decompression.

Let me briefly and colloquially talk about what a condensing boiler is.

The condensing boiler is to use the heat in the high-temperature flue gas generated by the boiler combustion to reduce the exhaust gas temperature when the boiler is designed. When the flue gas reaches the critical point of condensation, the condensation process will also release a small amount of heat, and the real condensing boiler will use these two parts of heat through scientific design.

Such a boiler is called a condensing boiler in the industry.

Different boiler manufacturers, different design levels, different condensation strategies and other factors have different utilization rates of heat in flue gas.

The heat utilization rate of condensing boilers is usually more than 100%, and the current maximum heat utilization rate can reach %. Although many boilers advertise a heat utilization rate of more than 100%, there are also some "fake" condensing boilers in the industry.

False"Condensation, usually only in the exhaust port to install a cold condenser, this design is actually unable to use the heat in the flue gas, let alone use the heat of the condensation process.

How to distinguish between a real and a fake condensing boiler.

See if there are any certification results for thermal efficiency from a national certification body.

2.Look at the working principle of the boiler, whether the heat of the flue gas can be transferred to the water system of the boiler, and whether it can play the purpose of heating the water.

True condensing boiler design working diagram.

3.Looking at the exhaust gas temperature, if the exhaust gas temperature is too high, more than 80 degrees, it is not a real condensing boiler.

The condensing boiler is a kind of high-efficiency and energy-saving boiler, which adopts advanced condensing technology to condense the water vapor in the flue gas into liquid, releasing a large amount of heat, thereby improving the thermal efficiency of the boiler. Compared with traditional boilers, the thermal efficiency of condensing boilers can be increased by more than 10%, which can greatly reduce energy consumption and environmental pollution.

The working principle of the condensing boiler is to exchange heat through the flue gas heat exchanger produced by combustion, so that the water backup vapor in the flue gas is condensed into a liquid, and a large amount of heat is released. The flue gas heat exchanger of the condensing boiler adopts a special material and structural design, which can effectively prevent the corrosion of the heat exchanger by the acid substances in the flue gas, thereby prolonging the service life of the boiler.

Condensing boilers have the following advantages:

1.Energy efficient:The thermal efficiency of the condensing boiler can be increased by more than 10%, which can greatly reduce energy consumption and environmental pollution.

2.Environmental protection and energy saving:The condensing boiler adopts advanced condensing technology, which can effectively reduce the emissions in the flue gas and reduce the pollution to the environment.

3.Safe & Reliable:The condensing boiler adopts advanced control system and safety protection device, which can ensure the safe operation of the boiler.

4.Easy to maintain:The maintenance of condensing boilers is more convenient than that of traditional boilers, because the flue gas heat exchanger of Fangshengxiang adopts special materials and structural design, which can effectively prevent corrosion.

In short, the condensing boiler is a kind of high-efficiency, energy-saving, environmentally friendly, energy-saving, safe and reliable, and convenient maintenance, and its application will be more widely promoted and applied in the future.

A condensing boiler is a boiler that uses condensing technology. The condensation technology is to carry the condensation waste heat ** inside the boiler to install or slide to absorb the sensible heat and latent heat released by the boiler, so as to improve the thermal efficiency of the boiler. Sensible heat is mainly the high-temperature flue gas produced by the boiler combustion and lack of wax, and the latent heat is mainly the heat released by the condensation of water vapor.

Condensing boilers with high condensing efficiency have thermal efficiencies ranging from 15% to 25% higher than ordinary boilers.

The working principle of the condensing gas boiler is to carry out the energy in the hot flue gas (generally about 140) discharged after the boiler combustion through a certain device, and the exhaust gas temperature after the first is only about 60, so that the thermal efficiency is about 10% improved, and about 10% of the gas is naturally saved, and at the same time, in the energy process, it can also reduce the emission of harmful gases and reduce environmental pollution.

The core of condensing technology is to reduce the heat loss of fuel combustion, efficiently absorb the heat energy generated by the fuel, and at the same time, due to the condensation of flue gas, the harmful substances in the flue gas are collected into the condensate, reducing the emission of acidic substances and other pollutants into the air.

Exhaust gas temperature is one of the basic design parameters of a boiler. When designing a boiler, the first step is to select this parameter.

The exhaust gas temperature of the boiler directly affects the economy of the boiler unit and the safety of the tail heating surface. Choosing a lower exhaust gas temperature can reduce the exhaust gas heat loss of the boiler, which is conducive to improving the thermal efficiency of the boiler, saving energy and reducing the operating cost of the boiler. Therefore, how to effectively reduce the exhaust gas temperature of the boiler and make it rational use is a major technical topic, and the condensing boiler can reduce the exhaust gas temperature by the following methods:

The silicon-aluminum integrated heat exchange furnace body is adopted, and the use of alloy materials makes the condensation technology get the best play. Aluminium is a very good conductor of heat transfer: 7 times stronger than steel, silicon guarantees a high resistance to corrosion.

Lightweight and durable alloy materials reduce the weight of the boiler and increase the service life of the boiler. The special furnace structure design maximizes the heat exchange area, makes the condensation effect outstanding, and the use efficiency reaches 110%. Condensing boilers save up to 40% energy compared to conventional boilers.

The above methods can effectively exhaust sensible heat and latent heat of vaporization in smoke exhaust in practical applications.

To sum up, the condensing boiler is the crystallization of heat transfer, physics, combustion, materials and other sciences. It stands out from conventional boilers with absolute economy. The promotion of condensing boilers is a shining of thinking and a change of concept, and at the same time, it will surely promote the development of the field of thermal engineering.

First, and most importantly, gas saving: the water in the make-up tank is heated by the condenser, which indirectly increases the temperature of the boiler inlet water and shortens the steam time of the boiler, so as to achieve the purpose of producing the same steam with less natural gas in a shorter time;

2. Reduce the exhaust temperature to meet the requirements of environmental protection;

3. Improve the utilization rate of natural gas.

Nowadays, many boiler factories produce their own condensers, some of which are made of carbon steel and some of which are made of stainless steel. Now many users have responded that the effect of Liwei brand condenser is better, because it is a stainless steel fin tube type, and the heat exchange effect is very good.

This question is good, super condensing boiler.

Many manufacturers in the condensing boiler market are introducing, these have foreign brands, domestic brands, and joint venture manufacturers, the principle of condensation is that the flue gas temperature is low enough to be below 58 degrees, condensate can be produced, and the energy efficiency is very high. However, the exhaust gas temperature is limited by the boiler return water, and if the exhaust gas temperature is under normal working conditions, it will not condense if it does not reach the condensation condition. So to make this point clear, of course, this is the vast majority of manufacturers, and there are very few manufacturers who have broken through this condition.

That is, the boiler exhaust gas temperature is no longer limited by the return water, even if the return water reaches 80 degrees, the exhaust gas temperature can be below 58 degrees. The condition for condensing is reached, which is called a super condensing boiler. This is a breakthrough in condensing boiler technology and an innovation in energy-saving technology.

Finally, we should be clear that not all condensing boilers can be used as condensing boilers, according to the customer's operating conditions. Hebei Sanlian rental service****.
