Description
Technical Field

[0002] The energy-saving exhaust system in a thermal power plant is an important piece of equipment for efficiently utilizing energy and reducing emissions. It mainly consists of an exhaust pipe, a heat exchanger, and a steam generator. During operation, the high-temperature, high-pressure exhaust gas generated by the boiler enters the heat exchanger through the exhaust pipe, transferring heat to cold water to produce high-temperature steam. The steam then enters the steam generator, where it is further pressurized and heated to drive a steam turbine to generate electricity. Any unused exhaust gas is treated and discharged in compliance with standards. This system improves energy efficiency and reduces environmental pollution through heat recovery, achieving the dual benefits of energy conservation and environmental protection.

The interfaces of the existing exhaust system cannot be replaced, and if the interfaces are corroded and damaged over a long period of time, the entire system must be replaced, resulting in a serious waste of materials.
