Description
Technical field
The utility model relates to a kind of vapourizing furnace, particularly a kind of biomass gasifying furnace.
Background technology
Biomass combustiblematerialss such as straw, rice husk, weeds and wood chip in stove not exclusively fuel and thermal chemical reaction can produce a large amount of inflammable gass, can replace conventional fossil energy and protection environment effectively.There is following shortcoming in traditional biomass gasifying furnace: one, fuel moisture content is required high (in moisture 15%), aerogenesis, aerogenesis time lack continuously, can only reach family's requirement of cooking, and can not be used for commerce and industry, and cost performance is low; Two, the air outlet of updraft type vapourizing furnace design, because of the stove endogenous substance can produce a large amount of water vapor bodies and tar when burning, the air outlet design of updraft type vapourizing furnace is on drying layer, so water vapour is more in the gas, water vapor is known from experience makes the institute's material gas calorific value that produces reduction, even be difficult to catch fire, and tar and water of condensation can be directed at the air outlet of directly giving vent to anger on top and stop up, and remove the tar difficulty; Three, burning can only burn down a part of raw material, and slag is charcoal or the siccative that varies in size, and can not be gasified totally, and can not reach environmental requirement, and be difficult to that promotional value is arranged.
Summary of the invention
The purpose of this utility model be intended to overcome the deficiencies in the prior art and provide simple in structure, working stability is reliable, gas production rate is big and can continue a kind of biomass gasifying furnace of aerogenesis.
The purpose of this utility model is achieved in that a kind of biomass gasifying furnace, comprise body of heater, the body of heater top is provided with water seal annular groove and movable bell, escape pipe, wherein: the middle and lower part of body of heater is provided with grate and is divided into the combustion chamber on top and the grey chamber of bottom, the combustion chamber bottom sides is provided with the igniting slag removing hole, ash chamber bottom sides is provided with ash removing hole, the combustion chamber inner-wall surface of described body of heater also is provided with crack thermosphere and flame retardant coating from outside to inside successively, the axle center at middle part, combustion chamber is provided with the back taper type gas collection awl that Open Side Down, and back taper type gas collection awl is communicated with escape pipe; The body of heater outside is provided with the muffler up and down that is communicated with top, combustion chamber and grey chamber, and muffler is provided with outer siphunculus, and siphunculus is provided with control valve outside.
The flame retardant coating at middle part, the described combustion chamber of above-mentioned a kind of biomass gasifying furnace is provided with the eck of inside undergauge, and described back taper type gas collection awl mouth is not higher than eck, guarantees that it is in the position of combustion chamber heat decomposition layer and obtains the less gas of moisture vapor.
Adopt a kind of biomass gasifying furnace of technique scheme, middle and lower part by body of heater is provided with grate and is divided into the combustion chamber on top and the grey chamber of bottom, reach and make the combustion chamber formation begin to form from the bottom to top the ash layer by grate, zone of oxidation, reducing zone, pyrolytic layer and drying layer, be located at the downward back taper type gas collection awl of axle center upper shed at middle part, combustion chamber, avoid drawing " the edge gas " of matter difference, and the back taper type gas collection awl of firmly putting that is in the combustion chamber heat decomposition layer is obtained the less gas of moisture vapor, be subjected to combustion gas heating simultaneously and the produced simultaneously a large amount of water vapors of dry fuel, top cooled via return air pipe top vapour outlet under the effect of negative pressure that water vapor rises to the combustion chamber cycles back to muffler air intake ash entrance chamber downwards, enter the combustion chamber and the scorching hot charcoal generation hydrogen that reacts through grate, combustion gas bodies such as carbon monoxide improve gas production rate, and do not need the water replanishing device of general updraft type vapourizing furnace.By between the shell of combustion chamber and flame retardant coating, the crack thermosphere being set, effectively reducing stove table temperature and guarantee high temperature in the stove.When normally using, vapourizing furnace closes bell (opening during refuel), close igniting slag removing hole (opening scarfing cinder when after working long hours, running into slagging scorification), close ash removing hole (opening during deashing), refuel, scarfing cinder and deashing are very little to the aerogenesis influence in the gas generation process, continuously aerogenesis.
The utlity model has advantages such as simple in structure, easy to use, with low cost and environmentally-friendly sanitary.
