Title:
EFFICIENT AND FLEXIBLE HEAT SUPPLY AND POWER GENERATION SYSTEM CAPABLE OF ACHIEVING ENERGY CASCADE RECYCLING
Document Type and Number:
WIPO Patent Application WO/2023/029404
Kind Code:
A1
Abstract:
Disclosed in the present application is an efficient and flexible heat supply and power generation system capable of achieving energy cascade recycling. The system comprises an intermediate pressure cylinder, a low pressure cylinder, a condenser, a first heat exchanger and a first heat exchange tube, wherein steam at a steam discharge port of the intermediate pressure cylinder is divided into two paths, one path of steam entering the low pressure cylinder and the other path of steam entering the first heat exchanger for heat exchange and then entering the condenser; steam at a steam discharge port of the low pressure cylinder enters the condenser; the first heat exchange tube is arranged in the condenser; and heat-supply return water passes through the first heat exchange tube for heat exchange and then enters the first heat exchanger for heat exchange again to then form heat supply water. The technical effects achieved by the system are as follows: the heat-supply return water first passes through the first heat exchange tube to be preliminarily heated, and then enters the first heat exchanger to be heated again, and the heat supply water is formed after undergoing two instances of heating, such that the energy utilization rate is higher; and after some of the steam discharged from the intermediate pressure cylinder passes through the first heat exchanger, the temperature thereof is still high; therefore, by introducing said steam into the condenser to preliminarily heat the heat-supply return water, waste heat can be deeply utilized, thereby realizing energy-saving heat supply.
