AIR PREHEATER FOR SMELTING FURNACE

摘要

PURPOSE: An air pre-heater for a melting furnace, which can reduce the maintenance costs by minimizing the generation of the differential pressure by the particulate in air, is provided to reduce air pollution and to incompletely combust exhaust gas. CONSTITUTION: An air pre-heater for a melting furnace comprises an inner container(110), an outer container(120), a chamber(150) for an inflow unit, a chamber(160) for an outflow unit, and an equally moving unit. The exhaust gas moves from the inner side of the inner container. Preheat air moves according to a flow path(130) of the outer container. The chambers for the influx unit and exhausting part are surrounded by an outer container. The chamber for the influx unit has an air injection hole(152) upon inside and an inflow chamber space part(151) in the inside.
