Abstract
The utility model relates to an efficient clean-burning multiple powder steam boiler. The boiler comprises a boiler body, and a drum, a furnace, a water wall, a sound wave soot blower and a threaded smoke pipe economizer which are arranged in the boiler body, wherein the water wall is arranged in the furnace and is a membrane water wall, the drum comprises an upper drum and a lower drum which are arranged vertically, and the threaded smoke pipe economizer and the sound wave soot blower are connected to the outlet of a flue respectively. According to the boiler, the overall thermal efficiency of the boiler is improved, the exhaust gas temperature is reduced, resources are fully saved and used, and using reasonableness and economy of boiler equipment and heating equipment can be improved.
Description
One, technical field
The utility model relates to a kind of boiler, especially a kind of efficient clean combustion multicomponent powder steam boiler.
Two, background technology
China's coal-burned industrial boiler ubiquity overall thermal efficient is on the low side at present, the problem such as dust, nitrogen sulfide emission are seriously polluted, boiler design efficient is 72%-80%, and average operating efficiency is about 60%-65% only, and average operating efficiency is lower 15-20 percentage point than Foreign Advanced Lerel; With approximately more than 50 ten thousand of Industrial Boilers, average size only is about 3 tons at present, and the coal yearly consumption is about 400,000,000 tons.Approximately 2,000,000 tons of annual discharging flue dust, approximately 6,000,000 tons of sulfur dioxide are the second largest coal-smoke pollution sources that is only second to thermal power plant.A large amount of dusts in use can be amassed in the rear arch of former boiler and convection bank bottom, heating surface is seriously covered by dust, boiler efficiency reduces greatly, if dust stratification situation especially severe, just need to be forced to the blowing out deashing, and each deashing all needs from hand-hole ash to be put in the boiler room temporarily, makes the boiler room very unhygienic, and frequent blowing out has a strong impact on the production heat supply of concentrated supply of heating in the city and large enterprise.
Adopt new and effective clean combustion multicomponent powder steam generator system to upgrade, substitute the poor efficiency Industrial Boiler, improve boiler thermal output, reducing pollutant emission is the main path of implementing the energy-saving and emission-reduction industrial policy.
Three, summary of the invention
The technical scheme that the utility model is taked is: the efficient clean fire coal powder steam boiler, comprise body of heater, drum, burner hearth, water-cooling wall, acoustic wave ash ejector, threaded flue economizer in the body of heater are set, described water-cooling wall is arranged in the burner hearth, described water-cooling wall is fin panel casing, described drum is divided into upper drum and lower drum, vertically arrange up and down, it is characterized in that: the exit of described heat exhausting pipe is connected with threaded flue economizer and acoustic wave ash ejector from inside to outside in turn.
The utility model has also designed described bottom of furnace body and has been provided with ash dropped unit.
The utility model has also designed described upper of furnace body and has been provided with peep hole, coke cleaning hole and beats burnt hole.
The beneficial effects of the utility model are: 1, the utility model further improves the overall thermal efficiency of boiler owing to having designed economizer and acoustic wave ash ejector, reduces exhaust gas temperature, reaches abundant energy savings, utilizes the purpose of the energy.
2, the utility model can improve boiler plant and reasonability and the economy used with hot equipment.
3, the utility model substitutes the valuable energy such as electricity, oil, gas with high-quality microfine coal, meets the long-term energy industry policy of country, and satisfies the day by day harsh environmental requirement of country fully.Steam generator system reaches low dust, protosulphide, low nitrogen nitride qualified discharge.

Five, the specific embodiment
Efficient clean combustion multicomponent powder steam boiler, comprise body of heater 1, drum, burner hearth 2, water-cooling wall 3, acoustic wave ash ejector, threaded flue economizer in the body of heater 1 are set, described water-cooling wall 3 is arranged in the burner hearth 2, described water-cooling wall 3 is fin panel casing, described drum is divided into upper drum 4 and lower drum 5, vertically arrange up and down, it is characterized in that: the exit of described flue is connected with threaded flue economizer 8 and acoustic wave ash ejector 9 from inside to outside in turn.
The utility model has also designed described body of heater 1 bottom and has been provided with ash dropped unit 6.
The utility model has also designed described body of heater 1 top and has been provided with peep hole 7.
The utility model boiler tail is provided with economizer; to reach to greatest extent energy savings; boiler thermal output can reach more than 90%; burner hearth rear portion comb has effectively been protected the rear portion furnace wall; reduced body of heater appearance temperature, reduced heat loss, water-cooling wall has adopted membrane wall structure; guarantee the tightness of burner hearth, each relevant position of boiler body reasonably is provided with the devices such as manhole, hand hole, flame-observing hole, inspection opening, explosion proof door.This boiler series is attractive in appearance, firm, practical.Reasonably water circulation system design; guarantee that security of system, steam quality are higher; steam quality reaches more than 98%; reached the top standard in design and structure; stable, heating curve is reasonable; accomplish efficient, energy-conserving and environment-protective, practicality, perfect unity attractive in appearance; Automatic Control and the protection of the aspects such as automatic control system is advanced, the high robot control system(RCS) of operating automation degree realizes feeding water fully, pressure, burning; have automatic demonstration, parameter setting; automatic control function is perfect, complete, reliable, and operating system is directly perceived, simple and direct.
The suitable comparatively broad microfine coal fuel of the utility model, stable operation can be regulated load range 50 ~ 110%.
