详情描述
The main difference between power plant heat pumps and building heating heat pumps lies in:
Heat Source and Heat Sink: The heat source is the low-temperature waste heat from power plants (lower temperature), and the heat sink is a centralized heating network or industrial process (higher temperature requirement). The large temperature difference demands higher efficiency from the system.
Scale and Integration: The system is large-scale, often deeply integrated with power plant steam turbines and boiler systems, capable of recovering waste heat from turbine exhaust or boiler flue gas.
Functional Combination: Enhances power plant heating capacity during the heating season; allows for combined cooling (such as absorption chillers) during certain periods, achieving simultaneous supply of cooling, heating, and electricity.
Key Advantages:
Significantly enhance energy efficiency: Convert low-grade waste heat into high-grade thermal energy, significantly improving the primary energy utilization rate of power plants.
Deep Load Fluctuation Regulation and Flexibility: By adjusting the heat pump load, assist in grid load regulation, enhance the flexibility of power plant operation.
Energy conservation and emission reduction: Reducing fossil fuel consumption and carbon emissions is a key technology for the green transformation of power plants.
