燃煤發(fā)電機組原理特點介紹
燃煤發(fā)電機組,是將煤等化石燃料的化學能轉化為電能的機械設備。 燃煤發(fā)電機組工作原理:是將煤燃燒產生的熱能,通過發(fā)電動力裝置(電廠鍋爐汽輪機和發(fā)電機及其輔助裝置等)轉換成電能。燃煤發(fā)電歷史較悠久,也是較為重要的一種。
Coal fired power generation units are mechanical equipment that converts 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 devices (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.
燃煤發(fā)電機組主要由燃燒系統(以鍋爐為核心)汽水系統(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(以汽輪發(fā)電機主變壓器等為主)控制系統等組成。前二者產生高溫高壓蒸汽;
The coal-fired power generation unit mainly consists of a combustion system (with the boiler as the core), a steam water system (mainly composed of various pumps, feed water heaters, condenser pipes, water-cooled walls, etc.), an electrical system (mainly composed of the main transformer of the steam turbine generator, etc.), and a control system. The first two generate high-temperature and high-pressure steam;
電氣系統實現由熱能機械能到電能的轉變;控制系統保證各系統安全合理經濟運行。燃煤發(fā)電作為一種傳統的發(fā)電方式也有其弊端和不足之處,如煤炭直接燃燒排放的SO2NOX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。因此要不斷地改進燃煤發(fā)電的行程,利用各種技術提高發(fā)電效率,減小環(huán)境污染,如對煙塵采用脫硫除塵處理或改燒天然氣,氣輪機改用空氣冷卻。
The electrical system realizes the transformation from thermal mechanical energy to 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 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 schedule 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 burning natural gas, and using air cooling for gas turbines.
