An ammonia-water mixed working fluid power cycle power generation system and coordinated control method

Abstract

The invention discloses an ammonia water mixed work medium power cycle power generating system and a coordinative control method. A first heat source adjusting valve and a second heat source adjustingvalve are correspondingly connected with a heat source pump or industrial waste heat; geothermal water or the industrial waste heat is injected back after passing through the first heat source adjusting valve; the second heat source adjusting valve is connected with a heat source end of an evaporator; the geothermal water or the industrial waste heat is injected back after passing through the heat source end of the evaporator, and a heat source side passageway is formed; after the evaporator passes through a separator, a path of the evaporator is connected with an inlet of a mixer through a pressure measuring transmitter, an adjusting valve and a turbine, and the other path of the evaporator is connected with the inlet of the mixer through a high-temperature heat regenerator and a throttling valve; and after passing through a low-temperature heat regenerator and a condenser, an outlet of the mixer is connected with an inlet of a work medium pump, and an outlet of the work medium pumpis connected with the evaporator through the low-temperature heat regenerator and the high-temperature heat regenerator, so that a work medium side circulation passageway is formed. According to the ammonia water mixed work medium power cycle power generating system and the coordinative control method, the production cost and the running cost of the system can be lowered easily, popularizing of the ammonia water mixed work medium circulation system adopting waste heat or renewable energy facilitates energy conservation and emission reduction, and the energy utilizing rate is increased.

Description
