ELECTRO-STATION OF COMBINED CYCLE WITH INTER-CYCLE GASIFICATION (VERSIONS), CONTROL DEVICE FOR SUCH ELECTRO-STATION (VERSIONS) AND CONTROL PROCEDURE FOR SUCH ELECTRO-STATION Russian patent published in 2011 - IPC F02C3/28 

FIELD: machine building.

SUBSTANCE: electro-station of combined cycle with inter-cyclic gasification consists of: gasificator (2) with solid fuel, air compressor (12), combustion chamber (11) for combustion of gas fuel from gasificator in mixture with compressed air from compressor, gas turbine (13), booster (21), circuit of gasified agent (A), bypass (D) of gasified agent, and multi-purpose valve (23). Bypass (D) adjoins an inlet branch of combustion chamber (11). Circuit (A) of gasified agent supply diverges from booster (21) rising pressure of gasified agent supplied to gasificator (2). Bypass (D) of gasified agent has valve (23) of control of withdrawn pressure. Value of flow or pressure of gasified agent supplied into gasificator (2) via circuit (A) of supply of gasifier agent can be controlled depending on degree of valve (23) opening. Valve (23) is located on bypass (D) of gasifier agent. There is eliminated necessity in installation of control accessories in circuit (A) of gasifier agent supply.

EFFECT: avoiding drops of pressure in circuit of gasifier agent supply, which allows essential reduction of pressure at output of booster.
