Claims

[Scope of utility model registration request]

(1) A coal-fired multi-burner in which the main burner, planet burner, and after-airport are sequentially arranged according to the direction of flow of combustion gas, and a slightly incomplete combustion zone, a gas phase reduction zone, and a complete combustion zone are formed in the combustion chamber, respectively. A coal-fired multi-burner furnace characterized in that a pre-combustion chamber is provided in a planet burner section that forms a gas phase reduction zone.

(2) A coal-fired multi-burner furnace according to claim 1 of the utility model registration claim, characterized in that the pre-combustion chamber has a cyclone furnace structure.
