Abstract
The invention discloses a waste gas afterheat boiler for an ore heat furnace, comprising a furnace barrel, a superheater, a coal economizer, a steel support, a smoke inlet device, a smoke outlet device, a front water-cooling wrapped wall, a middle water-cooling partition wall and a back water-cooling wrapped wall, wherein a cavity front room consists of the front water-cooling wrapped wall and the middle water-cooling wrapped wall, a tube bundle region back room consists of the middle water-cooling wrapped wall and the back water-cooling wrapped wall, and a full water-cooling wrapped dual-room structure consists of the cavity front room and the tube bundle region back room. The waste gas afterheat boiler has the beneficial effects that an ore heat kiln waste gas afterheat boiler adopts a combined type full water-cooling wrapped dual-room structure, is free of a horizontal smoke flue, jointly uses one water-cooling partition wall, is large in space, makes the most of radiant heat, is good for using high-temperature smoke, and is free of an accumulated ash attaching body, so that the difficulties of ash accumulating and coking on a heating surface can be effectively solved, and the afterheat use ratio can be improved.
