Abstract
The utility model relates to a vacuum boiler for biomass particles. The vacuum boiler has a steam boiler body. A vacuum condensation heat exchanger, a feeding system, a hearth, a grate, a flue, an air duct and an ash extractor are arranged in the body. The vacuum boiler is characterized in that: the front part of the hearth adopts a long flat arch, so that the front part of the hearth has a long separation distance to prevent backfire; communicated heat absorption water pipes are distributed on the inner sidewall of the hearth, so that high-water cooling degree low-temperature combustion is realized; and secondary air pipes of the air duct are longitudinally distributed, and staggered counter-blow is realized to form horizontal rotational flows. By the vacuum boiler, the biomass particles can be stably combusted, investment in the large area of the grate, the great height of the hearth and the like can be saved, and complete consistence with the combustion characteristics of the biomass particles is achieved.
Description
Technical field
The utility model relates to a kind of boiler, relates in particular to the vacuum boiler equipment of biomass burning particle.
Background technology
The vacuum boiler of prior art generally uses fuel oil, combustion gas or coal, does not have the biological substance for combustion particle.Limited the fuel applications scope of vacuum hot water boiler, along with the oil supply crisis increasingly sharpens, the cry of environmental protection requirement is surging day by day at present, and the biological particles secondary industry is just flourish.Because biological particles burning has the environmental protection characteristic that can compare favourably with fuel oil, just increasing steam boiler, bearing hot water boiler and the boiler of organic heat carrier of being applied to.Vacuum hot water boiler is high because of its heat transfer efficiency, and pot water does not outflow and do not have the water treatment of blowing requirement, and advantages such as boiler long service life are widely used in the units such as office, school, hospital, hotel and restaurant in the city.If can biomass granule fuel be applied to vacuum hot water boiler, but both alleviating energy crisis can be protected environment again.But present domestic this kind boiler product that still do not have.
Summary of the invention
The utility model main purpose provides a kind of simple in structure, reduced investment, easy to operate biological particles vacuum boiler.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of biological particles vacuum boiler, have the steam boiler body, and the vacuum condensation heat exchanger is housed in the body; Feeding system, burner hearth, fire grate; Cigarette, air channel and ash discharging gear; It is characterized in that: said furnace front adopts long jack arch, makes furnace front cut off distance like this, prevents tempering; The burner hearth inside wall is laid with the heat-absorbing water pipe of circulation, reaches high fractional cold low-temperature burning; Arrange before and after the secondary air channel in said air channel, staggered to blowing, form level rotary flow.
The above-mentioned technical problem of the utility model can also be further perfect:
As preferably, said fire grate adopts light-duty chain-belt type flakey fire grate.
As preferably, said ash discharging gear is the spiral ash hoist, is installed in the fire grate rear end.
As preferably, the media Containers of boiler body and heating surface area adopt pan shell type steam boiler easy to manufacture and that structural stability is good.
The beneficial effect of the utility model is: the media Containers of present technique and heating surface area adopt the body construction of easy to manufacture and the pan shell type steam boiler that structural stability is good; Fuel moves with chain fire-gate, and thickness is controlled by the fire grate movement velocity; Light-duty chain-belt type traveling-grate stoker, staggered to blowing know-how measure such as secondary wind is guaranteed biological particles smooth combustion and sufficient combustion in stove; Adopt this type of furnace, can the smooth combustion biological particles, can save the investment that grate area is big or burner hearth is crossed high aspect again, meet the burning feature of biological particles fully.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model.
Description of reference numerals: 1-traveling-grate stoker, 2-secondary air channel, 3-hopper, 4-spiral ash hoist, 5-steam boiler body.
The specific embodiment
Below through embodiment and combine accompanying drawing, the technical scheme of the utility model is further specified.
Embodiment:
Biological particles vacuum boiler as shown in Figure 1 comprises vacuum condensation heat exchanger, feeding system, burner hearth, traveling-grate stoker 1, cigarette, air channel and ash discharging gear is housed in steam boiler body 5, the body.Fuel falls on the traveling-grate stoker 1 through hopper 3, on traveling-grate stoker 1, moves with traveling-grate stoker, prevents that fuel is deposited in the front end of fire grate 1, the long jack arch of furnace front guaranteed fuel can be before fire grate 1 end burning, in case non-return is fiery; The scale chain grate 1 that does not leak has improved the utilization rate of fuel.Secondary air channel 2 front and back arrange that staggered to blowing, the secondary wind that is blown into burner hearth adopts the mode of level rotary flow, the flow process that has prolonged flue gas, and the disturbance that has increased flue gas helps fuel burning in burner hearth more.The lime-ash that burns the back generation is taken boiler out of by the spiral ash hoist 4 at traveling-grate stoker 1 rear portion.
Claims (4)
1. a biological particles vacuum boiler has the steam boiler body, feeding system, and burner hearth, fire grate, cigarette, air channel and ash discharging gear is characterized in that: said furnace front adopts long jack arch; The burner hearth inside wall is laid with the heat-absorbing water pipe of circulation; Arrange before and after the secondary air channel in said air channel, staggered to blowing.
2. biological particles vacuum boiler according to claim 1 is characterized in that: said fire grate adopts light-duty chain-belt type flakey fire grate.
3. biological particles vacuum boiler according to claim 1 and 2 is characterized in that: said ash discharging gear is the spiral ash hoist, is installed in the fire grate rear end.
