What kind of coal is good for home heating?

Household heating and coal burning are as follows:

1, bituminous coal: bituminous coal is one of the better domestic heating coals because of its high calorific value, long combustion time and stable combustion. However, bituminous coal will produce large smoke in the combustion process, which will cause great pollution to the environment, so attention should be paid to smoke exhaust when it is used.

2. Anthracite: Anthracite has high calorific value, high ignition point, combustion resistance and environmental protection, and produces relatively few pollutants. Therefore, from the perspective of environmental protection and flame resistance, anthracite is the first choice for household heating. However, the price of anthracite is relatively high, which needs to be selected according to personal economic situation.

3. Lignite: In some areas, such as Inner Mongolia, lignite is mainly used for heating. Lignite is a kind of coal with low coalification degree, and its calorific value is low, but its price is relatively cheap. However, the combustion efficiency of lignite is low, and it is easy to produce pollutants, so we should pay attention to environmental protection when using lignite.
