Title:
SOLAR-COAL HYBRID STEAM TURBINE SYSTEM BASED ON CASCADE UTILIZATION OF ENERGY, AND POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/037027
Kind Code:
A1
Abstract:
A solar-coal hybrid steam turbine system based on cascade utilization of energy, and a power generation system. The solar-coal hybrid steam turbine system based on cascade utilization of energy comprises a first medium tank (6), a second medium tank (7), a solar thermal system (1), a first heat exchanger (2), a second heat exchanger (5), a steam generation device (3), a steam turbine (4), and a regenerative system (9), wherein the first heat exchanger has a first heat absorption side inlet (201), a first heat absorption side outlet (202), a first heat release side inlet (203) and a first heat release side outlet (204), the first heat release side inlet being connected to the first medium tank; the steam generation device has a first water inlet (31) and a first steam outlet (32); the steam turbine comprises a high-pressure cylinder (401) and an intermediate-pressure cylinder (402), the high-pressure cylinder having a high-pressure steam inlet (4011) and a high-pressure steam outlet (4012), the high-pressure steam inlet being connected to the first steam outlet, and the high-pressure steam outlet being connected to the first heat absorption side outlet; and the intermediate-pressure cylinder has an intermediate-pressure steam inlet (4021) and an intermediate-pressure steam outlet (4022), the intermediate-pressure steam inlet being connected to the first heat absorption side outlet. The steam turbine system and the power generation system have low usage cost, have low energy consumption, and are environmentally friendly.
