燃煤發(fā)電機(jī)組，是將煤等化石燃料的化學(xué)能轉(zhuǎn)化為電能的機(jī)械設(shè)備。 燃煤發(fā)電機(jī)組工作原理:是將煤燃燒產(chǎn)生的熱能，通過發(fā)電動(dòng)力裝置(電廠鍋爐、汽輪機(jī)和發(fā)電機(jī)及其輔助裝置等)轉(zhuǎn)換成電能。燃煤發(fā)電歷史較悠久，也是較為重要的一種。

燃煤發(fā)電機(jī)組主要由燃燒系統(tǒng)(以鍋爐為核心)、汽水系統(tǒng)(主要由各類泵、給水加熱器、凝汽器、管道、水冷壁等組成)、電氣系統(tǒng)(以汽輪發(fā)電機(jī)、主變壓器等為主)、控制系統(tǒng)等組成。前二者產(chǎn)生高溫高壓蒸汽;電氣系統(tǒng)實(shí)現(xiàn)由熱能、機(jī)械能到電能的轉(zhuǎn)變;控制系統(tǒng)保證各系統(tǒng)安全、合理、經(jīng)濟(jì)運(yùn)行。燃煤發(fā)電作為一種傳統(tǒng)的發(fā)電方式也有其弊端和不足之處，如煤炭直接燃燒排放的SO2、NOX等酸性氣體不斷增長，使得我國的酸雨量增加，粉塵污染污染對(duì)人們的生活及植物的生長造成不良影響。因此要不斷地改進(jìn)燃煤發(fā)電的行程，利用各種技術(shù)提高發(fā)電效率，減小環(huán)境污染，如對(duì)煙塵采用脫硫除塵處理或改燒天然氣，氣輪機(jī)改用空氣冷卻。

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.
