Abstract
The utility model discloses an embedded device for a solar heat collection system and a power plant system. Normal temperature demineralized water in a demineralized water tank can be pumped in a solar heat collector through a first pump, heated by solar energy, and input in a hot water tank. Hot water in the hot water tank is pumped in a deaerator through a relay pump, and simultaneously steam drain in a drain tank is pumped in the deaerator through a drain pump. Steam in a steam turbine is sent to a steam inlet of the deaerator to heat up the water entered the deaerator so as to achieve a required temperature and complete deoxygenization. Water being deoxidized is output from a water outlet of the deaerator, and enters in a boiler steam bag after being heated by a heater. Steam burned by a boiler is sent to the steam turbine to drive a blade to generate electricity. Normal temperature deoxygenated water is heated through the solar heat collector, therefore less steam can enter a following deaerator, more steam can be supplied to the steam turbine to generate electricity, generating cost is lowered, and energy conservation and environment protection can be achieved while stable power supply is guaranteed.
