AI Technical Summary

Technical Problem

The heat exchange method of the thermal storage system requires high equipment heat resistance and the heat exchange process is difficult to control because the gas temperature is too high when the heat is first released.

Method used

A combined system of heat storage mechanism, heat exchange circulation path and boiler is adopted. The low temperature heat exchange medium exchanges heat with the heat storage mechanism to form a high temperature heat exchange medium, and exchanges heat with the boiler to generate high temperature and high pressure steam. The controller adjusts the flow rate and the temperature sensor controls the valve opening to achieve stable heat exchange control.

Benefits of technology

This technology enables the boiler to stably produce high-pressure, high-temperature steam, reduces the heat resistance requirements of the equipment, and improves the control precision of the heat exchange process.

Abstract

The present disclosure relates to a heat storage and release system and a heat storage and release method, which comprises a heat storage mechanism, a heat exchange circulation flow path, a boiler and a controller; the heat storage mechanism is used for receiving and storing heat, the heat exchange circulation flow path is used for storing heat exchange medium, the low-temperature heat exchange medium in the heat exchange circulation flow path exchanges heat with the heat storage mechanism to form high-temperature heat exchange medium, and the high-temperature heat exchange medium exchanges heat with the boiler to heat the water in the boiler to form high-temperature and high-pressure steam. Thus, the water in the boiler is heated circularly through the heat exchange circulation flow path, the valve opening of the first flow control valve or the second flow control valve is controlled according to the data of the first temperature sensor by the controller, the power of the driver is controlled according to the data in the second flowmeter, and the valve opening of the pressure regulating valve is adjusted according to the data of the pressure sensor, so that the heat exchange amount between the heat exchange circulation flow path and the boiler can be conveniently controlled, and the boiler can generate stable hot steam in temperature and pressure.
