TURBINE PLANT FOR LOW-POTENTIAL STEAM SOURCES Russian patent published in 2012 - IPC F01K7/20 F28B11/00 F01K13/02 

FIELD: machine building.

SUBSTANCE: turbine plant for low-potential steam sources includes steam turbine (1) with control system (3) and vacuum system (8). Vacuum system (8) includes the following components: exhaust pipe (2), condenser (4), non-condensable gas removal device (5) and condensate pump (6). On one of vacuum system components, i.e. exhaust pipe, condenser or non-condensable gas removal device, there installed is control valve (7) that is interconnected with atmosphere and opens air supply from atmosphere to condenser. Valve is controlled via impulse line (9) from steam turbine control system.

EFFECT: simpler control of steam turbine capacity.
