METHOD FOR DISTRIBUTION OF HEAT LOAD BETWEEN HEATERS OF NETWORK WATER IN CO-GENERATION TURBINE PLANTS

摘要

A method for distribution of heat load between heaters of network water in dual-purpose turbine plants is realized by passing delivery water in sequence through system water heaters of the lower and upper stages, grid valve control of pressure in lower stage of low pressure cylinder and steam consumption in system water heater of upper stage with gate between the upper takeoff of medium pressure cylinder and system water heater of the upper stage. Steam flow rate in heaters of the lower and upper stages are controlled till achieving optimal distribution of heat load between system water heaters.
