鍋爐的分類方法很多，可以按鍋爐的用途分，也可以按鍋爐（lú）的（de）結構、燃料（liào）種類分（fèn），還可以按水（shuǐ）循環形式、壓力分類。

　　1、按鍋爐（lú）用途分類

　　鍋爐可以作為熱能動（dòng）力鍋爐和供熱鍋爐（lú）。動力鍋爐包括電站鍋爐、船舶鍋爐和機車鍋爐等，相（xiàng）應用於（yú）發（fā）電、船（chuán）舶動力和機車動力。供熱鍋爐包括蒸（zhēng）汽鍋爐、熱水鍋爐、熱管鍋爐、熱（rè）風爐和載熱體加熱（rè）爐（lú）等，相應地得（dé）到蒸汽、熱水。熱風和載熱體等。

　　2、按鍋爐本體結構分類

　　按鍋爐結構分，主要分為火管鍋爐和水管鍋爐。火管鍋爐包括（kuò）立式鍋爐和臥式鍋爐，水管鍋爐包括橫水管鍋爐和豎水管（guǎn）鍋（guō）爐（lú）。

　　3、按鍋爐用燃料種類分類

　　按鍋爐用燃料種類分類為燃煤鍋爐、燃油鍋爐（lú）和燃氣鍋爐以及燃煤鍋爐的升級技術，油氣爐的替代產品---煤粉鍋爐，煤氣（qì）雙用鍋爐等。燃煤鍋爐按燃燒方式可以分為層燃鍋爐、室燃鍋爐和沸騰（téng）鍋爐。最新燃料為醇（chún）基燃料鍋爐，他將大大減少燃煤鍋爐對大氣環境的汙染。

　　Boiler classification many ways, according to the use of boiler points, you can also press the boiler structure, fuel types of points, but also by water cycle form, pressure classification.

　　1, according to the use of boiler classification

　　The boiler can be used as a thermal power boiler and a heating boiler. Power boilers include power plant boilers, ship boilers and locomotive boilers, etc., corresponding to power generation, marine power and locomotive power. Heating boilers include steam boilers, hot water boilers, heat pipe boilers, hot air furnaces, and heating medium heating furnaces, and accordingly steam and hot water are obtained. Hot air and heat carrier.

　　2, according to the boiler body structure classification

　　According to the boiler structure, divided into fire tube boiler and water tube boiler. Fire tube boilers include vertical boilers and horizontal boilers. Water boilers include horizontal and vertical water pipe boilers.

　　3, according to the type of boiler fuel classification

　　According to the types of fuel used for boilers, they are classified as upgrading technologies for coal-fired boilers, oil-fired boilers and gas-fired boilers and coal-fired boilers, and alternative products for oil and gas furnaces, such as pulverized coal boilers and gas dual-use boilers. Coal-fired boilers can be divided into stratum-fired boilers, room-fired boilers and boiling boilers according to the combustion method. The latest fuel for the alcohol-based fuel boiler, he will greatly reduce the coal-fired boilers on the air pollution.
