Description

Wind Volume coal becomes gas boiler
Technical field
the utility model relates to a kind of coal and becomes gas boiler, especially uses the Wind Volume coal that safety, hygienic environment-protecting and unit interval gas production are many to become gas boiler.
Background technology
china be a rich coal resources country.The reserves row third place in the world of coal, the output of coal is the first in the world, as developing country, within foreseeable period, Chinese development be take coal and is that main energy general layout can not change, therefore, how abundant coal is cheaply realized to the utilization of Environmental Safety, become the key subjects of China's economic construction.
at present, knownly take the civil boiler that coal is fuel and not only burn insufficient, cost is high, and in the unit interval, gas production is few, cannot meet the demand of simultaneously using compared with multi-user, in addition, existing coal becomes gas boiler easily to airborne release dust and sulfide gas, contaminated environment, is unfavorable for environmental protection, has directly restricted the development of civil boiler and has promoted the use of.
Utility model content
in order to solve existing coal, become the few problem of gas production in insufficient and unit interval of gas boiler burning, the utility model provides a kind of Wind Volume coal to become gas boiler, it is not only easy and simple to handle that this Wind Volume coal becomes gas boiler, use safety, in unit interval, gas production is many, and can the gas being discharged in atmosphere be filtered and be purified, being beneficial to environmental protection, the development that becomes gas boiler for civil coal provides excellent opportunity.
the utility model solves the technical scheme that its technical problem adopts: this Wind Volume coal becomes the body of heater that gas boiler is provided with a cartridge type, the bottom of body of heater is provided with the dust-collecting box of collecting dust, in body of heater, be provided with from the bottom up primary zone, secondary combustion chamber and heating agent chamber, primary zone, secondary combustion chamber and heating agent chamber are separated by the metallic plate of good heat conductivity, metallic plate central authorities between primary zone and secondary combustion chamber are provided with passage, the side of primary zone is provided with coal feed point and lighting-up tuyere, the indoor 1-3 of being fixed with of second-time burning the combustion gas stone or metal plate for standing a stove on as a precaution against fire being arranged in parallel up and down, the top of secondary combustion chamber is connected with many bottoms with metal tube, metal tube top is connected with gas cleaning plant and chimney successively, the side of body of heater is provided with pressure and takes into account temperature digital display meter, can monitor at any time and show the pressure and temperature of gas in body of heater, the side, below of body of heater is connected with two air blasts, thereby meet Wind Volume requirement, the ajutage of air blast is provided with the control valve that regulates air output, the top of body of heater is provided with gas delivery port.While using boiler, coal is sent into primary zone from coal feed point, and by lighting-up tuyere, coal is lighted, the coal of burning can produce coal gas, rises to combustion gas stone or metal plate for standing a stove on as a precaution against fire, at the gas furnace fire of making an inventory, this fire is the heating of metal tube and metallic plate, from the cool breeze that blows into two air blasts in heating agent chamber after scorching hot metallic plate and metal tube heat up, from gas delivery port, export, the gas producing during gas-fired enters gas cleaning plant by the tube chamber of metal tube, then by chimney, discharges boiler.
the beneficial effects of the utility model are that it is not only easy and simple to handle that this Wind Volume coal becomes gas boiler, uses safety, in unit interval, gas production is many, and can the gas being discharged in atmosphere be filtered and be purified, being beneficial to environmental protection, the development that becomes gas boiler for civil coal provides excellent opportunity.
Accompanying drawing explanation
