BURNING MELTING FURNACE, METHOD FOR BURNING AND MELTING AND WASTE HEAT USING GENERATOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To form a reducing atmosphere having an air ratio less than one and an oxidation atmosphere having one or more air ratio in one combustion chamber. SOLUTION: The burning melting furnace 3 comprises one combustion chamber 17 having a slag discharge port 13 and a burned gas exhaust port 15, a primary air supply nozzle 8 and a secondary air supply nozzle 10. In this case, a primary combustion area having a reducing atmosphere including less than one air ratio is formed near the port 13 by turning primary air in a swirling flow. Secondary air is supplied to the primary combustion gas to form a secondary combustion area of an oxidation atmosphere near the port 15.
