Abstract
The utility model relates to a biomass combustion and gasification device, in particular to a biomass direct-combustion gasification furnace, solving the problems in the present biomass furnace that the structure is complex, the operation is trouble, the produced tar is difficult to treat and the energy-saving and emission-reducing effect is poor. The biomass direct-combustion gasification furnace comprises a furnace and a hearth in the furnace, a fire grate is arranged at the lower part of the hearth, an ash bucket being in the sealed connection with the hearth and provided with a air inlet is arranged at the bottom of the hearth, a gap is formed between the hearth and the inner wall of the furnace to form a gasification duct, a gasification air inlet is arranged at the lower part of the furnace, a gasification air hole is arranged at the upper part of the hearth. The biomass direct-combustion gasification furnace has reasonable and simple structure design, convenient operation, has the direct-combustion function and the gasification combustion function under the direct-combustion action, no tar is produced in the gasification process, thus the energy-saving and emission-reducing effect is obvious, namely, the biomass furnace charge can be fully burnt and in the gasification combustion and no gasification carbon residue is produced.
Description
Technical field
The utility model relates to biomass (various stalks, branch, wooden unit and type piece) combustion gasification apparatus, is specially a kind of biomass direct-fired vapourizing furnace.
Background technology
At present, known biomass stove has two kinds: a kind of is vapourizing furnace, and another kind is the direct combustion stove.Vapourizing furnace is made up of fuel container, gas blower, pipe connecting, smoke exhaust pipe, coke discharging oil pipe and gas-cooker.Raw material after will pulverizing during use pack into compacting in the fuel container, light, blow from the bottom by gas blower, the combustion gas of generation is removed tar after pipe connecting is introduced gas-cooker can light through the coke discharging oil pipe.This Range structure complexity, troublesome poeration, a large amount of harmful tar that disengages in burning and the gasification are difficult to handle, and the carbon slag cleaning trouble behind the gasification, and combustion is disposed more difficult in addition.The single body of heater that the direct combustion stove is made up of burner hearth, fire grate, ash bucket, wind thorax, chimney etc., some uses gas blower, and some need not.Biomass are directly burning in the direct combustion stove.Direct combustion stove joint bavin effect is bad, and discharge index is very high, contaminate environment.
Summary of the invention
The utility model provides a kind of biomass direct-fired vapourizing furnace for the tar of the complex structure that solves existing biomass furnace and exist, troublesome poeration, generation is difficult to handle and the unfavorable problem of effects of energy saving and emission reduction.
The utility model is to adopt following technical scheme to realize: biomass direct-fired vapourizing furnace, comprise the intravital burner hearth of body of heater and stove, lower furnace portion is provided with fire grate, burner hearth bottom is provided with the ash bucket that is tightly connected with burner hearth and has blast inlet on it, keep the gap between burner hearth and the inboard wall of furnace body and form the gasification air channel, have the gasification blast inlet in the body of heater bottom, have gasification wind hole in upper furnace.During use, with the biomass furnace charge of filling it up with in the burner hearth after the processing, and the blast inlet on the ash bucket is opened, light from upper furnace, make the furnace charge of upper furnace realize directly burning, close the blast inlet on the ash bucket gradually then and enter vaporized state, at this moment, from the gasification air channel of wind between burner hearth and inboard wall of furnace body that body of heater bottom gasification blast inlet enters, the gasification wind hole of upper furnace enters burner hearth, make the furnace charge of upper furnace continue direct combustion, and spread downwards gradually, the heat downward radiation that upper furnace furnace charge direct combustion produces, conduction is gasified the furnace charge of lower furnace portion under high temperature and anaerobic environment, the combustion gas that gasification produces is risen and burnt at roof of the furnace, the burning of gasification burning is quickened the burning downwards of upper furnace furnace charge and is spread, and the heat that burning simultaneously produces further strengthens the gasification of lower furnace portion furnace charge.When gasification result weakens gradually, can open the blast inlet on the ash bucket, make the quarrel of the carbon after gasification continuation direct combustion in the burner hearth, until burning till ashes.
Biomass direct-fired gasification furnace structure described in the utility model is reasonable in design, simple, easy to operate, dual-use function with the gasification, and combustion under direct burning and the direct incendiary effect, gasification does not produce tar, and has a tangible effects of energy saving and emission reduction, be the biomass furnace charge can be fully directly and gasification, and combustion, and do not produce the vaporized carbon quarrel.
Description of drawings
Fig. 1 is the structural representation of biomass direct-fired vapourizing furnace described in the utility model;
Among the figure: 1-body of heater, 2-burner hearth, 3-fire grate, 4-blast inlet, 5-ash bucket, the 6-air channel of gasifying, the 7-blast inlet that gasifies, 8-gasification wind hole, 9-charging opening.
Embodiment
Biomass direct-fired vapourizing furnace, comprise the intravital burner hearth 2 of body of heater 1 and stove, burner hearth 2 bottoms are provided with fire grate 3, burner hearth 2 bottoms are provided with the ash bucket 5 that is tightly connected with burner hearth and has blast inlet 4 on it, keep the gap between burner hearth 2 and body of heater 1 inwall and form gasification air channel 6, have gasification blast inlet 7 in body of heater 1 bottom, have gasification wind hole 8 on burner hearth 2 tops.During concrete the manufacturing, ash bucket 5 stretches out body of heater, so that ash disposal.The gasification wind hole 8 on burner hearth 2 tops with the homogeneity of raising gasification air intake, thereby is improved the direct combustion effect along the circular permutation of burner hearth appearance, and the quantity in gasification wind hole 8 can (mainly be considered gasification rate) according to actual needs and determine.For making the lower furnace portion furnace charge realize abundant gasification, and combustion, the gasification wind hole 8 of burner hearth 2 top circular permutations is three rows.For flexibly connecting, be convenient to ash disposal between fire grate 3 and the burner hearth 2, but i.e. pull fire grate 3 during the ashes in removing burner hearth makes the ashes in the burner hearth fall into ash bucket fast.Be provided with charging opening 9 on body of heater 1 top, when gasifying approaching finishing,, can burn away from charging opening 9 continuous material in burner hearth as the need time-delay.During concrete the manufacturing, burner hearth 2 sectional dimension from bottom to top dwindles gradually, like this, can increase the lower furnace portion spatial furnace charge amount of holding, and prolongs the gasification time, simultaneously gasification burning is converged effect in uphill process, and gasification burning is more fully burnt.Routinely, have chimney on the body of heater 1.
