MAIN ELECTRIC AND HEATING LINE WITH CLOSED THERMAL SYSTEM Russian patent published in 2005 - IPC

FIELD: power engineering.

SUBSTANCE: system has boiler, steam turbine, electric generator, deaerator, feeding pump, and is additionally provided with gas-steam turbine plant block having low-pressure combustion chamber, steam-gas mixture heat utilization block and separated water utilization block. Steam-gas mixture heat utilization block has utilization boiler with high-pressure steam generator and additional low-pressure steam generator. Block for using separated water via low-pressure nutritious water pipeline is connected to low-pressure steam generator of utilization boiler and via irrigation water pipeline is connected to irrigation device of steam-gas mixture heat utilization block. Input of high-pressure steam generator of utilization boiler is connected by steam-gas mixture pipeline to output of steam-gas turbine plant. Low-pressure steam generator of utilization boiler is connected via low-pressure steam generator to additional combustion chamber of steam-gas turbine plant. Block for using separated water via pipelines for low-pressure nutritious water, irrigation water and separated water is connected to block for utilization of steam-gas mixture heat and via pipelines for cooled down and heated network water - to base main line. High-pressure steam generator is connected via high-pressure nutritious water pipeline and high-pressure steam pipeline to base main line.

EFFECT: higher efficiency.
