STEAM POWER PLANT WITH ADDITIONAL STEAM TURBINES Russian patent published in 2005 - IPC

FIELD: heat supply systems.

SUBSTANCE: proposed steam power plant with additional steam turbines includes power-and-heating plant with open power and heat supply system, gas-turbine plant with recovery boiler and make-up water heating and deaerating unit including at least two additional steam turbines with contact condensers which are placed in softened make up water line. Output of power and heating plant unit is connected by pipeline with input of contact condensers of additional steam turbines of make up water heating and deaerating unit. Output of steam recovery boiler unit of gas-turbine plant unit is connected by steam line with input of additional steam turbines. Input of steam recovery is connected by feed water pipeline with make up water heating and deaerating unit. Output of make up water heating and deaerating unit is connected by make up deaerated water pipeline with system heaters of power and heating plant unit and by feed water pipeline, with input of recovery boiler of gas-turbine plant.

EFFECT: facilitated deaeration and reduced cost of make up water deaeration system of heat supply system increased power and economy of power and heating plant.
