Sintering furnace

Abstract

The present application discloses a sintering furnace including a furnace chamber; an incineration device, the incineration device configured to be capable of heating exhaust gas to incineration to obtain purified gas; and a heat exchange device, wherein the heat exchange device is configured such that clean gas is heat exchanged with the purified gas to heat the clean gas and cool the purified gas prior to input into the furnace chamber. The sintering furnace of the present application uses high temperature gas discharged from the incineration device to heat the clean gas so that the clean gas can reach a preset temperature before being input into the furnace chamber, thereby reducing the number of heating elements required in the furnace chamber and taking advantage of residual heat of the high temperature gas discharged from the incineration device to reduce energy consumption.
