煤气发电机组的主要燃料为焦炉煤气。

　　The main fuel for gas generators is coke oven gas.

　　焦炉煤气的主要成分以及热值

　　The main components and calorific value of coke oven gas

　　焦炉煤气是煤在炼焦炉中高温干馏生产焦炭时产生的副产品。每生产1吨焦炭，大约会产生300-400立方米的焦炉煤气。

　　Coke oven gas is a byproduct produced during the high-temperature dry distillation of coal in a coking furnace to produce coke. For every ton of coke produced, approximately 300-400 cubic meters of coke oven gas are produced.

　　焦炉煤气的主要成分包含氢气（H?）、甲烷（CH?） 和一氧化碳（CO） 等可燃成分。由于焦炉煤气成分复杂，尤其是焦炉煤气里面还含有大量焦油、萘、硫化氢（H?S）、氨（NH?） 等杂质，所以不能直接用于发电，否则会严重损害设备。

　　The main components of coke oven gas include combustible components such as hydrogen (H?), methane (CH?), and carbon monoxide (CO). Due to the complex composition of coke oven gas, especially the large amount of impurities such as tar, naphthalene, hydrogen sulfide (H2S), ammonia (NH?), etc. contained in coke oven gas, it cannot be directly used for power generation, otherwise it will seriously damage the equipment.

　　要利用焦炉煤气发电，必须先将焦炉煤气进行深度净化处理才行，对于焦炉煤气中的焦油和萘，通常采用电捕法（高压静电吸附）等方式去除，防止它们冷凝附着在管道和设备内部，造成堵塞和腐蚀。

　　To generate electricity using coke oven gas, it is necessary to first undergo deep purification treatment. Tar and naphthalene in coke oven gas are usually removed using methods such as electrostatic adsorption to prevent them from condensing and adhering to pipelines and equipment, causing blockage and corrosion.

　　对于焦炉煤气中的硫化氢和氨，通常采用湿法脱硫（碱性溶液化学反应）和酸洗法（硫酸中和反应）等技术脱除，以减轻设备腐蚀并减少燃烧时二氧化硫等污染物的排放。

　　For the removal of hydrogen sulfide and ammonia in coke oven gas, wet desulfurization (alkaline solution chemical reaction) and acid washing (sulfuric acid neutralization reaction) technologies are usually used to reduce equipment corrosion and emissions of pollutants such as sulfur dioxide during combustion.

　　焦炉煤气经过净化后的洁净焦炉煤气，便可以作为燃料进行发电。

　　After purification, clean coke oven gas can be used as fuel for power generation.

　　焦炉煤气热值是决定发电机组输出功率和效率的关键参数。热值越低，产生同等电力所需的煤气量就越大。焦炉煤气的低位热值的标准范围大约在：

　　The calorific value of coke oven gas is a key parameter that determines the output power and efficiency of power generation units. The lower the calorific value, the greater the amount of gas required to generate the same amount of electricity. The standard range for the low calorific value of coke oven gas is approximately:

　　3,800 - 4,200 kcal/Nm?

　　3,800 - 4,200 kcal/Nm?

　　（或 16 - 18 MJ/Nm?）

　　(Or 16-18 MJ/Nm?)? ）

　　注：Nm? 指标准立方米，是在0°C、1标准大气压下的气体体积单位。

　　Note: Nm "refers to the standard cubic meter, which is a unit of gas volume at 0 ° C and 1 standard atmospheric pressure.

　　焦炉煤气的热值并非固定不变，它主要由其化学成分构成决定。如下图所示，焦炉煤气是一种多组分混合气体，其中既包含氢气、甲烷等高热值可燃成分，也含有大量不可燃的惰性成分，这种独特的组成决定了其最终的热值水平。

　　The calorific value of coke oven gas is not fixed and is mainly determined by its chemical composition. As shown in the figure below, coke oven gas is a multi-component mixture gas that contains both high calorific value combustible components such as hydrogen and methane, as well as a large amount of non combustible inert components. This unique composition determines its final calorific value level.

　　总之，焦炉煤气热值主要得益于氢气和甲烷的含量，但被高比例的不可燃惰性气体所稀释。在利用其发电或作为燃料时，必须充分考虑其热值特点，并针对其成分波动性进行相应的设备设计和运行调控。

　　In short, the calorific value of coke oven gas is mainly due to the content of hydrogen and methane, but it is diluted by a high proportion of non combustible inert gases. When using it for power generation or as fuel, its calorific value characteristics must be fully considered, and corresponding equipment design and operation regulation must be carried out based on its component fluctuations.
