FIELD: power industry.
SUBSTANCE: urban ore is supplied from receiving bunker 1 by means of tight box-type dosing unit 2 through downcomer 3 to inner cavity of tubular pyrolysis chamber 5 the walls of which are perforated with longitudinal slots to leave pyrolysis gas. Pyrolysis gas flows from pyrolysis chamber 5 to tubular pyrolysis gas collecting chamber 6, which in its turn is enclosed in external tubular chamber 7 with external heat insulating layer. Heating of urban ore and their thermo-chemical breakdown is performed owing to hot flue gases from gas burner 11, which are supplied to tubular chamber of initial heating 8 through tangential nozzles, and due to hot exhaust gases supplied from gas turbine electric unit 10 through inlet hole of external tubular chamber 7.
EFFECT: invention allows developing effective pyrolysis plant operating on urban ore.
