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、石油伴生气发电机组是:以石油伴生气为燃料的发电机组。石油伴生气的主要可燃成份为CH4、C2H6、C3H8、C4H10等，以甲烷CH4为主要成份其含量一般在80%左右石油伴生气产自油井，因此，石油伴生气发电机组主要用于有石油伴生气的油田。

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、发生炉煤气发电机组:是以发生炉煤气为燃料的发电机组。发生炉煤气是炭和水蒸气在少氧的炉膛中经氧化还原反应所得发生炉煤气的主要可燃成份为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%左右一般在发生炉煤气中含有大量的硫、苯、奈、焦油、水份和一定的灰份硫、苯、奈、焦油、水份和灰份对燃气发动机运行极为不利，发生炉煤气进入燃气发电机组前，必须进行预处理。

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、液化石油气发电机组:是以液化石油气为燃料的发电机组。液化石油气的主要成份为丙烷C3H8和丁烷C4H10液化石油气主要产自轻烃回收企业由于液化石油气便于储运因此液化石油气发电机组可广泛地用于气源价格较便宜的地区。

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、高炉煤气发电机组利用炼钢厂和炼铁厂的焦化气、高炉煤气和转炉煤气经过除尘、脱硫和脱焦油处理净化处理后通入燃气发电机组燃烧做功发电。

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.
