Coal-fired boilers vs gas-fired boilers

2022 / May / Fri
Coal-fired boilers and gas-fired boilers are two distinct types of boilers, the former uses coal as fuel and the latter uses gas fuel. What are the differences between these two types of boilers, apart from the different fuels used for combustion? Let the professional and technical personnel of Fangkuai boiler manufacturers tell you!

coal fired boiler conversion to gas

1. The exhaust gas of coal-fired boilers and gas-fired boilers is different

       Coal-fired boilers use coal as fuel. When the coal is burned, it will generate a lot of smoke and dust, causing serious pollution to the environment. However, the gas boiler with high stability does not emit black smoke after combustion, because the gas can basically be completely burned, and the black poison of the exhaust smoke can reach the zero Ringelmann level. What kind of pollution is very popular with our country's environmental protection department.

2. The heat loss of coal-fired boilers and gas-fired boilers is different

       In order to keep the coal-fired boiler with sufficient combustion intensity, manpower or other equipment is required to continuously add coal to the furnace. When intermittent operation is required, it takes a long time to increase the temperature in the furnace when it is restarted. Therefore, A large heat loss will be generated when pressing fire, and the gas boiler is very intelligent, it can start and stop within a few minutes, and it can heat up quickly during intermittent operation, thereby reducing the heat loss in this process.

3. Coal-fired boilers and gas-fired boilers have different treatment methods after combustion

       Coal-fired boilers will produce a large amount of ash after operation. At this time, the ash needs to be transported to a professional slag removal field for processing. However, gas-fired boilers use gas, and there will be no residual ash after combustion, so It does not need to be treated, which not only avoids environmental pollution, but also reduces the labor intensity of the enterprise and the storage and transportation of urban ash and slag.

Through these three obvious differences, everyone can see the difference between coal-fired boilers and gas-fired boilers, which is why my country strongly recommends people to use gas-fired boilers and eliminate coal-fired boilers.
