METHOD FOR CONTROL OF DELIVERY WATER IN DUAL-PURPOSE TURBINE PLANTS

摘要

A method for control of temperature of delivery water in dual-purpose turbine plants is realized by passing delivery water through a system water heater of the lower stage, a system water heater of the upper stage and bypass line for cross-over of delivery water from return main to direct one, control of temperature of network water at outlet of the turbine plant with bypass of the system water heater of the upper stage with part of delivery water from outlet of the heater of lower stage. Control of temperature of delivery water at outlet of the turbine plant is performed with part of total flow rate of bypassed delivery water, depending on flow rate of fresh steam for turbine plant for given temperature of environmental air.
