Abstract

Horizontal gas boiler belongs to industrial boiler's design and manufacture technical field. Physically have layering coal supply groove in both sides at the tube pot. Intermediate part at furnace has the extended surface tube partition wall. Have high -voltage pulse point firearm in the combustion chamber. Have roll excitation grate in furnace's bottom, be equipped with exciting motor on the other end of excitation roll grate. The utility model discloses a roll excitation grate to two furnace about setting up in furnace, by layering coal supply groove coal supply respectively, burning in turn, the gasification agent feeding mechanism is incessant to filling air or steam in the furnace during burning, and the coal gas that produces in succession forces coal gas from last outlet flue downward flow under the effect of induced air power, lighted by high -voltage pulse point firearm in the combustion chamber. When the burning produces the slag to grate production jam, stir the slag through roll grate fin, make the slag bulk, the exciting force of recycling the high -frequency will stick the ash and shake off. Fundamental flue gas emission compliance problem and the present gasification boiler solved can not produce coal gas, influence production and the workman slight big problem of working in succession.

Description

Horizontal gas-fired boiler

Technical field

This utility model belongs to design and the manufacturing technology field of Industrial Boiler.

Background technology

The fuel that China's boiler is conventional is exactly coal, this is because China is world's first coal power. For a long time, extensive combustion system causes severe contamination to environment, and long-term it was verified that the clean combustion mainly vaporization of coal and liquefaction, boiler is commercial production, the thermal source that domestic life is indispensable. Existing vertical boiler can not continuously generate coal gas, but commercial production cannot be interrupted supply. Therefore existing coal-burning boiler has been not suitable with environmental protection and industrial requirement. Additionally existing boiler grate is grate formula, and the slag that burning produces easily blocks fire grate and affects combustion efficiency. Workman must be often manual penetrating to ensure normal operation of boiler, increases the labor intensity of workman.

Summary of the invention

For above-mentioned situation, the purpose of this utility model is to provide a kind of Horizontal gas-fired boiler not changing fuel and can continuously generating coal gas, solves noxious gas emission and the problem that reduces labor intensity better, meets commercial production needs.

This utility model is adopted the technical scheme that by solving the problems referred to above; Its body is horizontal. On the top of body with shell pot, shell pot is built with high temperature threaded flue and low temperature threaded flue. In shell pot both sides with layering coal supply groove. At the pars intermedia of burner hearth with extended surface tube partition wall. It is left hearth on the left of extended surface tube partition wall, is right bearth on the right side of extended surface tube partition wall, on the top of left and right burner hearth with gas exit. At the rear belt combuster of left and right burner hearth, with high-voltage pulses device in combustor. At the rear portion of combustor with secondary furnace. Partition wall bottom between combustor and secondary furnace is with exhanst gas outlet. In the bottom of burner hearth with rolling exciting fire grate, rolling on exciting fire grate with sprocket wheel.Roll on the fire grate bearing of exciting fire grate one end with motor, with drive sprocket on motor output shaft, couple the sprocket wheel on every fire grate by chain. At fire grate center with gasifying agent import, fire grate radially with gasification agent outlets. Equipped with shock electric machine on the other end of exciting rolling fire grate. This utility model adopts and rolls exciting fire grate, and arranges two burner hearths in left and right in burner hearth, by layering coal supply groove coal supply, alternate combustion respectively, can continuously generate coal gas. Its operation principle is; Gate turnover panel in the lower openings of coal supply groove is by opening manually, and bunker coal layering falls on rolling exciting fire grate, stirs slag by rolling fire grate fin, makes slag bulk, recycles high-frequency exciting force and shaken off by glutinous ash. Burning is to add air injection or steam by aerator in burner hearth, by air or steam as gasifying agent, make to produce coal gas during coal combustion and take in burner hearth, owing to the effect burner hearth of air inducing power is always negative pressure, force coal gas to flow downward from upper outlet flue, lighted by high-voltage pulses device in combustor. Then enter secondary furnace through exhanst gas outlet, instead discharge back into after low temperature threaded flue then through the high temperature threaded flue in shell pot. The heat exchange of boiler is realized by water screen tube and threaded flue. This product structure simple designs is reasonable. Owing to adopting horizontal layout, roll exciting fire grate, separate two burner hearths with extended surface tube partition wall, layering coal supply respectively, coal gas can be continuously generated, directly burn, fundamentally solve fume emission problem up to standard and existing gasification boiler can not continuously generate coal gas, affect the problem produced.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail; Body 1 is horizontal. On the top of body with shell pot 12, shell pot is built with high temperature threaded flue 13 and low temperature threaded flue 14. In shell pot both sides with layering coal supply groove 6. At the pars intermedia of burner hearth with extended surface tube partition wall 3. It is left hearth 2 on the left of extended surface tube partition wall, is right bearth 4 on the right side of extended surface tube partition wall, on the top of left and right burner hearth with gas exit 11. At the rear belt combuster of left and right burner hearth, with high-voltage pulses device 5 in combustor. At the rear portion of combustor with secondary furnace. Partition wall bottom between combustor and secondary furnace is with exhanst gas outlet 10. In the bottom of burner hearth with rolling exciting fire grate 7, rolling on exciting fire grate with sprocket wheel. Roll on the fire grate bearing of exciting fire grate one end with motor, with drive sprocket on motor output shaft, couple the sprocket wheel on every fire grate by chain. At fire grate center with gasifying agent import 8, fire grate radially with gasification agent outlets 9. Equipped with shock electric machine on the other end of exciting rolling fire grate.
