Abstract

The invention relates to the technical field of steel smelting equipment, in particular to a heat tube type waste heat boiler system externally arranged beside a large flue of a sintering machine. The heat tube type waste heat boiler system externally arranged beside the large flue of the sintering machine comprises the large flue of the sintering machine, bypass flues, steam superheaters, a primary heat tube type evaporator, a secondary heat tube type evaporator, a steam pocket and a water feeding system. A plurality of steam guide tubes are arranged on the large flue. According to the heat tube type waste heat boiler system externally arranged beside the large flue of the sintering machine, because the heat tube type waste heat boiler is directly arranged beside the large flue of the sintering machine, an existing site of the sintering machine is fully utilized to recycle waste heat resources of the sintering machine, reasonable, effective and gradient utilization of energy is achieved, the equipment investment is small, and the occupied area is small; and generated superheated steam is used for power generation, and remarkable economic and social benefits are achieved. Meanwhile, the heat tube type waste heat boiler system externally arranged beside the large flue of the sintering machine cannot influence production of the sintering machine and can be widely applied to the industry of sintering machines of steel enterprises.

Description

technical field [0001] The invention relates to a heat pipe type waste heat boiler used outside a large flue of a sintering machine, which belongs to the technical field of iron and steel smelting equipment. Background technique [0002] In the existing iron and steel production equipment, the waste heat of exhaust gas from the belt cooler or ring cooler of the sintering machine has been generally recycled to generate superheated steam for power generation or other purposes. However, the exhaust heat of the sintering machine itself has not been widely recycled, and only a few iron and steel enterprises have adopted external (built-in) waste heat recovery devices (waste heat boilers, heat pipe steam generators, etc.). As we all know, after the sintering machine is ignited, as the sintering trolley moves from the nose to the tail, the induced draft fan on the flue is used to suck the combustion-supporting air to carry out back-burning. way to the chimney. Under normal circum...
