燃煤发电机组，是将煤等化石燃料的化学能转化为电能的机械设备。 燃煤发电机组工作原理:是将煤燃烧产生的热能，通过发电动力装置(电厂锅炉、汽轮机和发电机及其辅助装置等)转换成电能。燃煤发电历史较悠久，也是较为重要的一种。
燃煤发电机组主要由燃烧系统(以锅炉为核心)、汽水系统(主要由各类泵、给水加热器、凝汽器、管道、水冷壁等组成)、电气系统(以汽轮发电机、主变压器等为主)、控制系统等组成。前二者产生高温高压蒸汽;电气系统实现由热能、机械能到电能的转变;控制系统保证各系统安全、合理、经济运行。燃煤发电作为一种传统的发电方式也有其弊端和不足之处，如煤炭直接燃烧排放的SO2、NOX等酸性气体不断增长，使得我国的酸雨量增加，粉尘污染污染对人们的生活及植物的生长造成不良影响。因此要不断地改进燃煤发电的行程，利用各种技术提高发电效率，减小环境污染，如对烟尘采用脱硫除尘处理或改烧天然气，气轮机改用空气冷却。

Coal fired power generation units are mechanical equipment that convert the chemical energy of fossil fuels such as coal into electrical energy. The working principle of coal-fired power generation units is to convert the thermal energy generated by coal combustion into electrical energy through power generation equipment (such as power plant boilers, steam turbines, generators, and their auxiliary devices). Coal fired power generation has a long history and is also an important type.
Coal fired power generation units are mainly composed of combustion systems (with boilers as the core), steam water systems (mainly composed of various pumps, feedwater heaters, condensers, pipelines, water-cooled walls, etc.), electrical systems (mainly consisting of steam turbine generators, main transformers, etc.), control systems, etc. The first two generate high-temperature and high-pressure steam; The electrical system realizes the transformation from thermal energy, mechanical energy to electrical energy; The control system ensures the safe, reasonable, and economical operation of all systems. Coal fired power generation, as a traditional power generation method, also has its drawbacks and shortcomings. For example, the continuous increase in acidic gases such as SO2 and NOX emitted from direct coal combustion has led to an increase in 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 stroke of coal-fired power generation, use various technologies to improve power generation efficiency, and reduce environmental pollution, such as using desulfurization and dust removal treatment for smoke and dust or switching to natural gas combustion, and using air cooling for gas turbines.
Characteristics of coal-fired power generation units:
1. The generator set is powered by a diesel engine and matched with a well-known brand generator.
