Description

Technical Field

[0002] A thermal power plant refers to a thermal power plant that uses steam extraction or exhaust from steam turbines to provide heat to users while generating electricity. Its main working principle is to use the hot water generated by the thermal power plant for heating after reheating. It usually uses wastewater to generate electricity. However, during power generation, it is necessary to add acidic and alkaline solutions to the wastewater for purification, which requires the use of a dosing device.
