Working process of the present utility model: with different biomass material----size, thickness, variform rice husk, cotton stalk, maize straw, corn cob, shell, the saw foam, branches etc. are put into roasting kiln and are ignited, make biomass material destructive distillation in the stove by the oxygen feed rate of control in the roasting kiln, the flue gas that produces in pyrogenous process enters the whirlwind air water separator successively, strainer of tar, the tar secondary filter, cooling separator, get rid of moisture and wood tar oil in the flue gas by aforesaid device, enter in the gas mixer at last and mix, form the higher inflammable gas of utility value and by the gas output tube output of mixing tank.
Compared with prior art, advantage of the present utility model and effect are:
1. energy-conserving and environment-protective: this device does not have the discharging of flue dust substantially and wood tar oil is separated, and not only can not pollute atmosphere and soil, and guarantee the output of gasification gas and stablizing of quality.
2. economic benefit is considerable: utilize this to install 6.5 tons of biomass of every consumption, and through the burning of 8 hours control oxygen, but 6200 cubes of inflammable gass of output, its calorific value be 4200 kilocalories/cube, but 2.2 tons of output biomass charcoals simultaneously, calorific value is at 6000 kilocalorie/kilograms, 90 kilograms in wood tar oil, 400 kilograms of pyroligneous liquors.The said products is sold by the existing market valency, and 1 ton of biomass of every consumption can be made a profit 300 yuan.
3. sharp useless: this device can mix various biomass materials burning destructive distillation, gasification, has changed the situation of biomass material single utilization, has enlarged the scope that biomass material utilizes, and has increased the continuity of vapourizing furnace work.
4. can be by the oxygen feed rate of control roasting kiln, with the destructive distillation degree of control biomass material, the destructive distillation degree suitably then can be produced a certain amount of charcoal in roasting kiln.
