Problems solved by technology

[0003] Although the "pot" of these products is designed with sufficient heating surface, a large amount of dust accumulates in the heat exchange parts of the tangled and vertical tubes, which seriously affects the effect of heat conduction. At the same time, because of the backward combustion technology used, the concentration of smoke and dust is very high. , a large part of these granular dusts are "coking carbon particles" that have not been burned out in the "furnace". a large amount of coal resources
During the operation of the whole boiler equipment, the Ringelmann blackness of the flue gas exhausted in the light loa

Abstract

The invention relates to a chain grate and double swirl smokeless steam boiler, a thermal equipment, including shell, water wall, convection of the group, the drum and lower coal-fired devices, the coal-fired device includes coal installation, chain grate , the front furnace arch and the back furnace arch on the coal-fired, between the front arch and a chain grate constitute the front hearth, between the back furnace arch and the chain grate constitute back hearth, between the front furnace arch and the back furnace arch have the combustion gas export, the front hearth fall into upper hearth and nether hearth ,and its cross-section present two symmetry R form structure, the nether hearth of the two R form front hearth communicate, on the front hearth side wall has a tuyere open into upper hearth , the back of the front hearth connect the combustion gas export. The structure is simple reasonable, and low cost, full combustion, high thermal efficiency, low energy consumption, solved black smoke fouling problems, protection of the environment.

Description

technical field [0001] The invention relates to a chain grate type double swirl pure smokeless steam boiler, which belongs to thermal equipment. Background technique [0002] At present, the large-scale chain grate steam boiler, which has been vigorously promoted in China and has more advanced performance, belongs to the SZL series products. The structure includes the shell, water-cooled wall, convection tube group, drum and lower coal-fired device. Coal loading device, chain grate, furnace front arch and furnace rear arch. The front furnace is formed between the furnace front arch and chain grate, and the rear furnace is formed between the furnace rear arch and chain grate. There are combustion hot gas outlets between them, and the thermal power is 4.2MW-30MW, or even larger. All major boiler factories have finalized drawings and manufacturing inspection standards issued by the Ministry of Labor. [0003] Although the "pot" of these products is designed with sufficient hea...
