METHOD OF OPERATION OF POWER AND HEAT GENERATION PLANT Russian patent published in 1997 - IPC

FIELD: heat-power engineering. SUBSTANCE: during operation of plant, chilled water from supply line is passed through built-in bundle of condenser for preheating; flow rate of steam fed to condenser for its preheating is regulated; flow rate of water and its temperature are also regulated. As soon as preset load has been attained, turbine is stopped, CND is opened and its bladed rotor is replaced with rotor whose disks of last stages have no blades, after which cylinder is closed, turbine is started and preset load is picked up; then pressure is measured in adjustable heating tap and temperature of direct line water is measured as well; then flow rate of steam to condenser is increased by fully opening the steam inlet of CND and preset pressure in heating tap is regulated through change of flow rate of line water and temperature of direct line water are regulated through change of flow rate of line water. EFFECT: enhanced efficiency. 1 dwg
