Does the larger the damper of a coal stove have the greater the firepower?

The damper control should be commensurate with the fire power and the oxygen demand of the fuel. The damper should be larger when the fire is large, and the damper should be small when the fire is small. It is wrong to blindly emphasize the large damper.

Technically speaking, the combustion of coal (solid fuel) is much more complicated than that of gas; my country is a large coal-consuming country, but our country’s research on coal combustion and coal-burning appliances (especially household coal-burning appliances) Stoves) improvements have been few and far between. Whether it is an earth stove, a kang stove or a commercial stove, its coal-fired technology is mainly based on natural supply and exhaust, and the improvement in structure and technology is very slow.

The essence of the damper is the air channel, which is a necessary condition for solving the combustion air problem. Due to less research, the combustion of coal stoves is still based on experience. For example, when the stove is lit, there is only a little fire, so the air demand is not large, and the damper is much smaller. When the fire burns louder, the damper must be opened larger accordingly. To make an already large fire smaller, turning down the damper is to control the air volume, and sealing the fire is to control the exhaust emissions. The two have the same purpose, so some people often use them in combination.

What is a coal stove? Our country has a large territory, and different places have different names for the same thing, which can easily lead to misunderstandings. When consulting online, try to use popular terms, so you have a greater chance of getting help.
