MOBILE POWER PLANT Russian patent published in 1995 - IPC

FIELD: power supply for regions affected by Chernolyl disaster. SUBSTANCE: mobile gas-electric power plant using wood contaminated by radio nuclides as fuel has double-stage gas generator (main stage 6 and afterburning stage 7) provided with drum-type drier 11, classifier 30 separating ash from coal, and ash containerization unit 27. Fuel is dried out in air admitted by fan 19 and heated in heat exchanger 20. Radio nuclides are carried away with air flow irrespective of their form on surfaces of fuel lumps. Radio nuclides are separated in cyclone 22 and condenser 24 together with mud and liquid from waste air and passed by means of feeder 23 to entrance in afterburning stage 7 wherein red-hot coal is supplied from classifier 30. Ash leaving afterburing stage 7 and classifier 30 goes to accumulator 28 which also admits hard fragments of generator gas trapped in cleaner 9. Clean generator gas is fed from cleaner 9 to internal-combustion engine 2 and the latter sets in rotary motion electric generator. EFFECT: provision for operation in contaminated areas. 3 cl, 3 dwg
