FIELD: engines and pumps.
SUBSTANCE: invention relates to heat power engineering, particularly to combined-cycle units with boiling bed. Proposed plant comprises boiler and boiling bed at pressure, housing accommodating furnace with boiling bed and cyclones, gas turbine unit, steam turbine, heat exchangers to cool gases coming out of gas turbine unit and boiler outlet ash. Swirling chamber is arranged in boiler exhaust gas path, downstream of cyclones, to receive swirled gases coming out of cyclone and combustion gas. Gas temperature in said chamber is maintained higher than that of fluid gas. Swirling chamber bottom accommodates fluid slurry separator. Swirling chamber outlet accommodates tube bundle to catch slurry and solid ash catcher is arranged there behind.
EFFECT: higher reliability and efficiency.
