1. Natural gas generator set: it is a generator set with natural gas as fuel. The main combustible component of natural gas is methane CH4  methane concentration is generally 70% - 97%. Natural gas is mainly produced from natural gas wells or process tail gas of oil associated gas after light hydrocarbon recovery. Natural gas generator sets are mainly used in gas fields with natural gas resources, light hydrocarbon recovery enterprises and enterprises that can obtain natural gas use rights along natural gas pipelines.

2、石油伴生氣發電機組是:以石油伴生氣為燃料的發電機組。石油伴生氣的主要可燃成份為CH4、C2H6、C3H8、C4H10等，以甲烷CH4為主要成份其含量一般在80%左右石油伴生氣產自油井，因此，石油伴生氣發電機組主要用于有石油伴生氣的油田。

2. Oil associated gas generator set is a generator set with oil associated gas as fuel. The main combustible components of petroleum associated gas are CH4, C2H6, C3H8 and C4H10. Methane CH4 is the main component  its content is generally about 80%. Petroleum associated gas is produced from oil wells. Therefore, petroleum associated gas generator sets are mainly used in oil fields with petroleum associated gas.

3、發生爐煤氣發電機組:是以發生爐煤氣為燃料的發電機組。發生爐煤氣是炭和水蒸氣在少氧的爐膛中經氧化還原反應所得發生爐煤氣的主要可燃成份為CO、H2另外有少量的甲烷CH4等，其中CO含量一般在25%-35%左右，H2含量一般在6%-10%左右CH4含量一般在2%-6%左右CnHm含量一般在0.5%-3%左右一般在發生爐煤氣中含有大量的硫、苯、奈、焦油、水份和一定的灰份硫、苯、奈、焦油、水份和灰份對燃氣發動機運行極為不利，發生爐煤氣進入燃氣發電機組前，必須進行預處理。

3. Producer gas generator set: it is a generator set with producer gas as fuel. The producer gas is obtained by the oxidation-reduction reaction of carbon and water vapor in the furnace with less oxygen. The main combustible components of the producer gas are co, H2  and a small amount of methane CH4. The content of CO is generally about 25% - 35%, the content of H2 is generally about 6% - 10%, the content of CH4 is generally about 2% - 6%, and the content of CnHm is generally about 0.5% - 3%. Generally, the producer gas contains a large amount of sulfur, benzene Nai, tar, water and certain ash  sulfur, benzene, Nai, tar, water and ash are extremely unfavorable to the operation of gas engine. Pretreatment must be carried out before generator gas enters gas generator unit.

4、液化石油氣發電機組:是以液化石油氣為燃料的發電機組。液化石油氣的主要成份為丙烷C3H8和丁烷C4H10液化石油氣主要產自輕烴回收企業由于液化石油氣便于儲運因此液化石油氣發電機組可廣泛地用于氣源價格較便宜的地區。

4. LPG generator set: it is a generator set with LPG as fuel. The main components of liquefied petroleum gas are propane C3H8 and butane C4H10  liquefied petroleum gas is mainly produced by light hydrocarbon recovery enterprises. Because liquefied petroleum gas is convenient for storage and transportation  therefore  liquefied petroleum gas generator set can be widely used in areas with cheaper gas source prices.

5、高爐煤氣發電機組利用煉鋼廠和煉鐵廠的焦化氣、高爐煤氣和轉爐煤氣經過除塵、脫硫和脫焦油處理凈化處理后通入燃氣發電機組燃燒做功發電。

5. The blast furnace gas generator set uses the coking gas, blast furnace gas and converter gas from the steelmaking plant and ironmaking plant. After dust removal, desulfurization and tar removal treatment, they are connected to the gas generator set for combustion and power generation.
