STEAM-TURBINE PLANT Russian patent published in 2000 - IPC

FIELD: power engineering and other industries using steam turbines. SUBSTANCE: steam-turbine plant has turbine- generator set, regenerative water heating system incorporating low-pressure heater, deaerator, and high-pressure heater, boiler with air heater, and modified air-condensing unit with rotation drive communicating through pipe connections with air heater, as well as probable secondary heat loads (hothouses, fish farms, and the like). Air-condensing unit has two impellers and two centrifugal air blowers mounted on common hollow shaft to form annular space between non-bladed sides; shaft has holes to provide communication between shaft hollow and annular space; hollow shaft communicates with turbine outlet and annular space, with regenerative water heating system; air outlet pipes of centrifugal air blower impellers communicate with inlet of boiler air heater and with other heat loads. In addition, annular space walls bear circular bosses. Exhaust air recovery makes it possible to reduce pollution of natural water reservoirs thereby raising plant efficiency. EFFECT: improved environmental friendliness and reduced cost of plant. 2 cl, 1 dwg
