RECYCLING CARBON POWER PLANT Russian patent published in 2021 - IPC F01K25/10 

FIELD: energy.

SUBSTANCE: invention relates to energy. The utilization carbon dioxide power plant contains a utilization heat exchanger 1, consisting of two heat exchange sections - the main and bypass heaters (MH 2 and BH 3) of high pressure carbon dioxide (СО₂ h.p.), located in the utilization heat exchanger 1 in the specified sequence along the heating coolant, high-temperature recuperator (HTR) 4, low-temperature recuperator (LTR) 5, high-temperature turbine 6, low-temperature turbine 7, СО₂ cooler 8 and compressor 9. Compressor 9 is communicated at the inlet by СО₂ l.p. with the outlet of the cooler 8 for CO₂ l.p., at the outlet for СО₂ h.p.- with СО₂ h.p. inlets BH 3 and LTR 5 through a control switchgear - a three-way valve 10, placed together with its electric actuator inside a sealed circuit in the high-pressure CO₂ h.p. path. in front of the inputs of НТР 5 and BH 3 for СО₂ h.p. and made with the possibility of adjusting the distribution of the flow rate of СО₂ h.p. between the inputs НТР 5 and BH 3 according to the condition of maintaining the temperatures of СО₂ h.p. at the outputs of HTR 4 and BH 3 at the same level. HTR 4 at the outlet for high pressure СО₂ h.p. also communicated with the inlet of low-temperature turbine 7 for MH СО₂ h.p., and BH3 at the outlet for MH СО₂ communicated with the input of MH 2 for high pressure СО₂.

EFFECT: invention allows increasing efficiency and capacity of the utilization power plant.
