Is the air outlet temperature of household floor heating gas boiler high?

The temperature of the air outlet of the domestic floor heating gas boiler depends on the type of boiler used:

1.Using the condensing furnace, the exhaust temperature can be as low as 40, generally 40-70

2.Non-condensing furnace is used, and the exhaust temperature is generally hundreds of degrees Celsius. Generally between 120 and 150.

3.The lower the exhaust temperature, the higher the thermal efficiency and the better the heat utilization rate of the gas wall-hung boiler.

Knowledge about condensing wall-hung boilers

1.Condensing wall-hung boiler: The hot gas discharged from the chimney of the traditional furnace is all used through the condensing system.

2.The condensing wall-hung boiler with a hot ** device in the flue gas of the ordinary gas wall-hung boiler is called pseudo-condensation in the industry.

3.The full premixed condensing wall-hung boiler is a real condensing wall-hung boiler, which does not need a heating device, and its own heat exchanger is a heat exchange device.

4.The advantages of a condensing boiler are twofold:

One is energy-saving, because it recycles the hot gas generated during its own use.

The other is environmental protection, and the exhaust gas will be used again.

5.According to the energy efficiency standard of wall-hung boiler - GB20665-2006, when the water supply and return temperature is 80 60, the thermal efficiency of non-condensing wall-hung boiler under full load is about 90%, and the thermal efficiency of condensing wall-hung boiler at full load is about 99%.

6.When the temperature of supply and return water is 50 30, the thermal efficiency of the condensing wall-hung boiler is about 105%% and up to 109% at full load.

7.The condensing wall-hung boiler** is also much more expensive than the ordinary wall-hung boiler, so you can choose according to your own economic ability.

The gas boiler is mainly based on gas, and the electricity consumption is very small, if the gas boiler load is 50w, it is 36 kWh of electricity a month. Due to kilowatt-hour electricity.

1. Check your temperature sensor.

2. The exhaust temperature is only high and is still in the normal range.

3. Look at the chimney for white smoke or black smoke, and adjust the burner if it does.

4. Check the scale of the boiler.

The temperature of the furnace outlet of the gas hot water boiler is about 220 degrees under normal circumstances, and 980 degrees will burn out your chimney, and the burning temperature of 980 degrees in the furnace will not burn out the boiler if there is no shortage of water in the boiler.

The furnace outlet temperature is 980 degrees, which does not damage the boiler.

100 11 250 or so.

At present, the main purpose of commercial gas boilers is to provide heating or bathing water and domestic hot water for supermarkets, hospitals, schools, hotels, communities (mainly in central cities, areas with convenient gas facilities), bathing centers, etc. Because the ash, sulfur content and nitrogen content in the gas are lower than those of coal, the combustion is sufficient, the amount of dust in the flue gas is very small, and the emission is easy to meet the national standards required by the gas equipment, which can greatly reduce the pollution to the environment and have good environmental performance.

In addition, the gas boiler does not need auxiliary equipment such as gas, slag remover, dust collector, grate, etc., which saves the investment of boiler equipment, so it is suitable for commercial use.

Under normal circumstances, different types of gas boilers, in the case of flue gas waste heat exchanger at the flue outlet without installing a flue gas waste heat exchanger, the exhaust gas temperature is about 100-250.

Water supply between 50 and 45 is fine. It mainly depends on whether you want intermittent heating or 24-hour heating. The world is chaotic intermittently, and the search code file needs to be at a high temperature. 24 hours can be low-point mold grip.

The outlet water temperature of the underfloor heating boiler is lower than that of radiator heating, and the maximum temperature of underfloor heating is 65 degrees.

The state bai is regulated like this: du

The rated evaporation capacity is greater than or equal to 1t h

Steam boiler row. The DAO smoke temperature is not higher than 170.

The boiler energy-saving technical supervision regulations belong to Article 8 of TSG G0002-2010 The design of boiler exhaust gas temperature should comprehensively consider the safety and economy of the boiler.

1) Steam boiler with rated evaporation capacity less than 1t h, not higher than 230;

2) The rated thermal power is less than that of the hot water boiler, not higher than 180;

3) Steam boilers with rated evaporation capacity greater than or equal to 1t h and hot water boilers with rated thermal power greater than or equal to 170;

4) Organic heat carrier boiler with rated thermal power less than or equal to, not higher than +50 for imported medium;

5) The rated thermal power is greater than that of the organic heat carrier boiler, not higher than 170.

The maximum exhaust temperature of natural gas BAI boiler is about 120-180 degrees, and the higher the exhaust temperature.

zhi indicates that the boiler efficiency DAO is lower.

The exhaust gas temperature of the non-condensing technique is in.

Answer: About 180 degrees (the national standard shall not be less than 110 degrees), the exhaust gas temperature is related to the thermal energy conversion efficiency, and it is also related to the air coefficient. From the point of view of energy saving, the use of condensing gas modular furnaces is recommended. It is at least about 30% more energy-efficient than that of ordinary boilers.

Because the exhaust gas temperature is too high, and the condensation technology uses the temperature of the exhaust smoke to heat the water again).

There are no regulations on the exhaust gas temperature in the country, but there are regulations on minimum efficiency.

In the context of energy conservation and environmental protection, the demolition and elimination of coal-fired boilers in various places has entered the substantive implementation stage, and the demolition and reform measures for highly polluting coal-fired boilers have been introduced one after another.

"Coal to electricity" has become a major trend of boiler replacement in the next few years, as a substitute for coal-fired boilers, natural gas boiler orders are expected to usher in explosive growth.

It is about 120-180 degrees, and the higher the exhaust gas temperature, the lower the boiler efficiency. There are no regulations on the exhaust gas temperature in the country, but there are regulations on minimum efficiency.

Smoke extraction for non-condensing technology.

The temperature is about 180 degrees (the national standard stipulates that it shall not be lower than 110 degrees), and the exhaust gas temperature is related to the thermal energy conversion efficiency, and the return is related to the air coefficient.

From the point of view of energy saving, the use of condensing gas modular furnaces is recommended. It is at least about 30% more energy-efficient than that of ordinary boilers. Because the exhaust gas temperature is too high, and the condensation technology uses the temperature of the exhaust smoke to heat the water again).

For the question you raised, it is generally impossible, and the answer is that if the temperature of the outlet of the boiler furnace 1 reaches a change. One, it's probably the temperature is wrong. Second, the furnace has a negative pressure of nuclear socks

Generally, the energy of coal-fired boiler combustion must be maximized, so the boiler outlet flue gas temperature given by the general boiler design list is about 140 and 150, but there are also about 180 220.

The calculation of outlet flue gas temperature should be traced back to the source, that is, the change of flue gas energy and temperature should be considered from the flue gas generation temperature, the exchange and transmission of energy in the process of flue gas collection and transportation, the requirements and influence of purification facilities on flue gas temperature, the influence of flue gas heat exchanger or flue gas waste heat utilization, and the heat loss in the flue gas and chimney. Theoretically speaking, the outlet flue gas temperature of the chimney can be obtained through the energy conservation equation, but the actual process is often very complicated, so the outlet flue gas temperature is generally determined by the method of actual measurement and analogy. In addition, there are some emission standards or specifications that also have clear regulations on the exhaust gas temperature, such as:

Technical requirements for the identification of environmental protection products Small and medium-sized oil-fired and gas-fired boilers (HBC31-2004) stipulate that the exhaust gas temperature of hot water boilers should be less than 180, and that of steam boilers and domestic boilers should be less than 200.

Unlike the BAI coal-fired boiler, the temperature is controlled in order to prevent sulfur condensation and corrosion of the metal due to the sulfur content in the fuel of the coal-fired boiler. The oil-fired and gas-fired boilers do not need to control this index, as long as they can meet the operation, but whether it is gas or coal, the exhaust gas temperature has been determined when the boiler is designed, and this indicator cannot be controlled during operation. The exhaust gas temperature of the gas boiler is generally lower than 100, if it exceeds 100 in operation, it means that the heat transfer of the boiler is blocked, which is fouling and needs to be treated.

160-180 degrees. The larger the boiler, the lower the temperature.

1. If it is a floor heating, the temperature of the heating water should not exceed 60 degrees, and the temperature of the radiator heating water should not exceed 70 degrees.

2. It is quite convenient for users equipped with wall-hung boiler thermostats to set the temperature, and the room temperature of how many degrees is needed can be accurately set directly through the thermostat;

3. Users who do not have a thermostat need to adjust the wall-hung boiler according to the actual situation of the room to control the water temperature of the floor heating or radiator and other heat dissipation terminals, under normal circumstances, the water temperature of the floor heating should be set to 40 50, and the water temperature of the radiator is set to 50 60.

Winter heating temperature setting range, radiator setting temperature: 30-80; Floor heating set temperature: 30-60.

Generally, you can adjust it at will within this range, and you feel that if the heat can be turned down a little, if it is cold, it will be turned up a little, and now the temperature in the north (Xi'an) is generally set at 55-60 degrees.

Question: What should be the water pressure in the furnace when it is adjusted to 6o degrees?

Ask me if the water pressure in the furnace shows yes, is it okay?

As long as it is not less than that.

Hello question, thank you!

The heating wall-hung boiler regulates the temperature according to the needs of your own home.

In general, around 50 degrees is fine. If you want to grow quickly, you can do it between 70 and 80.

You just need to feel the warmth in the house.
