METHOD FOR REGULATING TEMPERATURE OF HEATING SYSTEM WATER IN POWER-AND-HEAT SUPPLY TURBOPLANT Russian patent published in 2003 - IPC

FIELD: heat power engineering. SUBSTANCE: according to invention, in process of temperature regulation of heating system water of power-and-heat supply turboplant after peak heater connected to turbine chamber by steam supply pipeline with regulator installed in pipeline, steam is fed to regulator from two or more turbine chambers, steam pressure in said chambers is measured and, basing of pressure measurements, steam saturation temperature in each chamber is calculated, absolute difference of steam saturation temperature and preset heating temperature of heating system water is determined and then steam is supplied to regulator from chamber in which said difference is minimum, and at full opening of regulator afterheating of heating system water is carried out by acting onto steam distributing members of turbine high pressure part. EFFECT: increased economy of power-and-heat supply turboplant when regulating temperature of heating system water after peak heater. 2 dwg
