ADVANTAGE - The apparatus provides purified combustible gases to meet requirements of low-pollution gas generation in an eco-friendly manner by efficient utilization of biomass.    DETAILED DESCRIPTION - The apparatus includes a sewage sludge gasification plant, gas cooling element, gas electric catching focal unit, and a gas generating device. The sewage sludge gasification plant includes bucket elevator, screw feeder, refiner, gasification unit, blower, and screw feeder. The bucket elevator, screw feeder and refiner are connected to upper end of the refiner, blowers and gasification furnace combustion chamber, where the screw feeder is connected to pyrolysis and gasification chambers including gas outlet. The gas cooling element comprises air-cooled heat exchanger (7), a water-cooled heat exchanger (10), a condensate tank, a cooling tower, and a pump. The gas filtration device includes electric tar, fan, and tar ponds. The pump is connected to the condensate tank, and the water-cooled heat exchanger. An INDEPENDENT CLAIM is included for a method for generation power by using sludge biomass gasification, which involves:    (A) adding fuel in combustion blower and furnace fuel for combustion at 360-440 degrees C;    (B) transferring biomass particles to gasifier feed layer through bucket elevator, screw feeder and refiner;    (C) burning the biomass particles at 400-450 degrees C for 1-1.5 hours to give sufficient thermal gasification and occurrence of carbonization reaction of alkanes, carbon monoxide, hydrogen, tar and combustible gases and water vapor;    (D) discharging alkanes, and a mixed gas of carbon monoxide, hydrogen, tar, and water vapor from the gasifier at 180-250 degrees C;    (E) cooling the discharged from in air-cooled heat exchanger outlet at 120- 150 degrees C;    (F) cooling the combustible gas at 30-40 degrees C; and    (G) collecting the cooled combustible gas through pipeline into trap drip for power generating units.
