AI Technical Summary
Coal-fired power units face problems such as insufficient peak capacity, insufficient high-parameter steam supply capacity, thermal-electric decoupling affecting safety, and excessively high pressure and temperature of heating return water in high-parameter industrial steam supply, leading to reduced heating economy and equipment damage.
The system adopts a coupled architecture of molten salt energy storage technology and steam thermal storage system. By combining molten salt energy storage unit, steam thermal storage unit, external steam supply unit and high-parameter heating return water unit, the boiler and steam turbine generator set are decoupled. A smart heating control platform is configured for collaborative monitoring and optimized scheduling.
It achieves stable output of high-parameter industrial steam supply capacity of coal-fired units during deep peak shaving, maximizes the recovery of heating return water working fluid and heat, improves heating economy, and enhances energy utilization efficiency and equipment life through hydraulic turbine and high-temperature iron removal device.
