STRUCTURE OF SECONDARY COMBUSTION CHAMBER

摘要

PROBLEM TO BE SOLVED: To provide a structure of a secondary combustion chamber having the function of efficiently and immediately quenching high temperature exhaust gas after reburning and decomposing dioxin and the like by water spray.

SOLUTION: This structure of the secondary combustion chamber 10 cools gas by the water spray in an upper part in the secondary combustion chamber 10 of the exhaust gas generated in a furnace. A diametrally contracted part 16 squeezed more than an inner diameter of the combustion chamber is arranged on the way from a tail end part 13a of a secondary combustion part (a combustion zone 13) to a cooling zone 14 with the water spray.
