METHOD OF SECONDARY COMBUSTION OF BURNED GAS AND SECONDARY COMBUSTION APPARATUS OF WASTE INCINERATOR

摘要

PURPOSE: A secondary combustion method of burned gas is provided to treat combustible gas and dust contained in burned gas. CONSTITUTION: A secondary combustion method comprises the steps of: injecting hot burned gas to a combustion furnace(22) having a certain combustion path via a burned gas injection part(21) from a combustion furnace incinerating waste: supplying air in the direction out of the direction of burned gas proceeding of the combustion path to make the burned gas generate turbulence within a certain range in the combustion path when supplying air into the combustion furnace via many paths: incinerating the hot burned gas by the oxygen in the supplied air: discharging the burned gas via an outlet(221) prepared on the upper part of the combustion furnace: and adding flames to the burned gas using a subsidiary burner(231) when the temperature of the burned gas flowed into the burned gas injection part is under a certain degrees.
