FIELD: engines and pumps.
SUBSTANCE: dual-purpose turbine plant with production and heating steam extractions comprises turbine. Said turbine consists of high-, medium-, and low-pressure sections with exhaust branch pipe. Exhaust branch pipe is connected with condenser steam intake branch pipe and cooling water feed and discharge branch pipe. Pipeline top heating steam extraction with shutoff element arranged thereon communicates low-pressure section with delivery water heater with delivery water feed and discharge pipelines with shutoff elements arranged thereon. Turbine exhaust pipeline or condenser steam intake branch pipe is communicated via pipeline with shutoff element with pipeline of top steam extraction at section between shutoff element and delivery water heater. Sections of deliver water feed and discharge pipelines of delivery water heater between shutoff elements and heater of top steam extraction are communicated with condenser cooling water feed and discharge pipelines, respectively.
EFFECT: power output increased by 15% with complete or partial production steam extraction.
