Structure of coal-fired generator set

Coal-fired generator sets are mainly composed of combustion system (boiler as the core) and steam-water system (mainly composed of various pumps, water heaters, condensers, pipes, water walls, etc.). ), electrical system (mainly turbine generator, main transformer, etc. ), control system, etc. The first two generate high-temperature and high-pressure steam; The electrical system realizes the conversion of thermal energy and mechanical energy into electrical energy; The control system ensures the safe, reasonable and economical operation of each system. As a traditional power generation method, coal-fired power generation also has its drawbacks and shortcomings. For example, the acid gases such as SO2 and NOX emitted by direct combustion of coal are increasing, which increases the amount of acid rain in China, and dust pollution has a negative impact on people's lives and plant growth. Therefore, it is necessary to continuously improve the journey of coal-fired power generation, use various technologies to improve power generation efficiency and reduce environmental pollution, such as desulfurization and dust removal of smoke and dust, burning natural gas instead, air cooling of gas turbines, etc.
