COMBINED HEAT POWER PLANT WITH OPEN DISTRICT HEATING SYSTEM

摘要

FIELD: heating.SUBSTANCE: combined heat power plant with open district heating system comprising cogeneration steam turbine, turbine with industrial and heat extractions, and raw water heating unit, additionally has raw water heating system in the turbine condenser with industrial and heat extractions, containing recirculation regulator, recirculation valve with input and two output branch lines, recirculation line with pipelines and recirculation pump. Output of the turbine condenser with industrial and heat extractions is connected with pipeline of heated raw water via the first output branch of recirculation valve with unit of raw water heating, and via it the second output branch is connected with the recirculation pipeline of cold raw water and with output of this condenser.EFFECT: invention increases electric power and economical efficiency of the combined heat power plant with increased power generation at heat consumption.1 dwg
