The invention relates to the technical field of boilers, in particular to an in-boiler coal putting and double-furnace combustion device. The technical problems that in an existing boiler double-furnace combustion device, a shared coal scuttle isolation belt is formed between an ignition furnace and a main combustion furnace, so that the structure between the ignition furnace and the main combustion furnace is huge and complex, resistance on coal supply of a coal scuttle is formed by a flue, and smooth coal supply of the coal scuttle is influenced are solved. According to the technical scheme, the in-boiler coal putting and double-furnace combustion device is composed of an ignition furnace, a main combustion furnace, a vertical type reciprocating furnace grate arranged in the ignition furnace, a horizontal mechanical furnace grate or an inclined push reciprocating furnace grate arranged in the main combustion furnace and a coal supply device; the coal supply device is composed of an ignition furnace coal supply device body and one to four main combustion furnace coal supply device bodies.
Description
technical field [0001] The invention relates to the technical field of boilers, in particular to a double furnace combustion device for coal application in a furnace. Background technique [0002] The vertical sowing primer combustion device with the application number of 2009201498841 can also be called the pilot furnace, and the furnace where the boiler layer combustion grate is located that undertakes the complete combustion state primer produced by the vertical sowing priming combustion device can be called the main combustion chamber. Furnace, this kind of boiler double-hearth combustion device is composed of the vertical bottom fire combustion device and the furnace where the boiler layer combustion grate is located. This kind of boiler double furnace combustion device, in the structure of the vertical bottom fire combustion device, the shared vertical square cylindrical coal hopper for applying coal to the vertical reciprocating grate and the layer combustion grate fr...
