Vertical smokeless steam boiler of Venturi tube effect

Abstract

This invention relates to a venturi smoke-free vertical steam boiler, a thermal equipment, including shell, curved pipes and combustion devices, the outside bending pipes is placed in the box, between the introvert pipes form a hot gas cavity, beneath the cavity is the combustion chamber, beneath the combustion chamber is the grate, beneath the grate is the ash chamber, on the combustion chamber has stove door to coal, and on the ash chamber has a gray ash doors, ash chamber is equipped with a tuyere, on the top of combustion chamber has narrow high temperature gas export, above the export has a secondary combustion chamber, the cross section of the secondary combustion chamber is circular, the secondary combustion chamber has a secondary tuyere, on the top of the secondary combustion chamber has high temperature gas export, the high temperature gas export connect hot gas chamber. A rational structure, solve the problem of coal-smoke emission, carry out smokeless emission, high thermal efficiency, conservation of coal resources and the environment.

Description

technical field [0001] The invention relates to a Venturi tube effect type pure smokeless vertical steam boiler, which belongs to industrial thermal equipment. Background technique [0002] At present, vertical hand-fired steam boilers occupy a relatively large share in the market. The typical one is the LSG type vertical curved water tube boiler. The structure includes the shell, curved water pipes and combustion devices. The hot gas cavity is formed between the bent water pipes, the combustion furnace of the combustion device is located below the thermal gas cavity, the grate is located below the combustion furnace, and the ash chamber is located below the grate, and a coal charging furnace door is provided corresponding to the combustion furnace, which corresponds to the ash chamber There is an ash outlet, and the ash chamber is equipped with a combustion-supporting tuyere. The high-temperature flue gas rushing up from the combustion furnace enters the hot gas chamber to ...
