Non-ferrous smelting furnace exhaust gas treatment method containing oxygen and SO2 in exhaust gas

摘要

PPROBLEM TO BE SOLVED: To dispense with dust collecting equipment for processing exhaust gas and absorbing equipment of SO2 gas; to reduce a plant and equipment investment amount; to prevent an increase in a processing gas quantity of a sulfuric acid factory by offsetting a part of diluent air; to prevent dust from sticking to a radiation part and a staying part pipe wall; and to stabilize boiler operation. PSOLUTION: In this processing method of nonferrous refining furnace exhaust gas, oxygen and SO2 are included in the exhaust gas of blowing in exhaust gas of a nonferrous refining furnace including oxygen and SO2 from a radiation part inlet part of a nonferrous refining furnace boiler.
