What fuel do heating companies in northern cities use for heating?

Heating companies in northern cities usually use coal or natural gas as heating fuel. Due to the low temperature in winter in the north, heating needs a lot of heat, so heating companies in these cities usually use large boilers or cogeneration equipment for heating.

In coal-fired heating, high-temperature flue gas generated after coal combustion is transported to heating equipment such as radiator and floor heating through pipelines for heat exchange, and heat energy is transferred to indoor air to realize heating. Coal-fired heating has the advantages of high thermal efficiency and low cost, but at the same time, there are also problems of emission of pollutants such as carbon dioxide, sulfide and nitrogen oxides produced by combustion.

Natural gas heating is to use natural gas as fuel to supply heat through gas-fired boilers or cogeneration equipment. Natural gas heating has the advantages of high combustion efficiency, environmental protection and no pollution, but the price of natural gas is higher. In some cities, the price of natural gas heating may be more expensive than that of coal heating.

In addition to burning coal and natural gas, heating companies in northern cities may also use other fuels for heating, such as biomass fuel, diesel oil and petroleum. When selecting fuel, heating enterprises need to comprehensively consider fuel price, environmental protection requirements, energy security and other factors to ensure the normal operation of heating equipment and the heating needs of users.
