MAIN ELECTRICAL AND HEATING LINE WITH OPEN THERMAL SYSTEM Russian patent published in 2005 - IPC

FIELD: power engineering.

SUBSTANCE: system has boiler, steam turbine, electric generator, deaerator and feeding pump, and additionally has steam-gas turbine plant block with low pressure burning chamber, steam-gas mixture heat utilization block and block for using separated water. Block for utilization of heat of steam-gas mixture has utilization boiler with steam generator of high pressure and additional low-pressure steam generator. Block for using separated water via low pressure nutritious water pipeline is connected to input of 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 via steam-gas mixture pipeline to output of steam-gas turbine plant. Low-pressure steam generator of utilization boiler is connected via low-pressure steam pipeline to additional combustion chamber of gas-steam turbine plant. Block for using separated water via pipelines for low-pressure nutritious water, irrigation water and separated water is connected to steam-gas mixture heat utilization block, and via softened heated and deaerated nutritious water pipeline - to base heat and electricity 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.
