　　The main fuel for gas generators is coke oven gas.

　　焦?fàn)t煤氣的主要成分以及熱值

　　The main components and calorific value of coke oven gas

　　焦?fàn)t煤氣是煤在煉焦?fàn)t中高溫干餾生產(chǎn)焦炭時(shí)產(chǎn)生的副產(chǎn)品。每生產(chǎn)1噸焦炭，大約會(huì)產(chǎn)生300-400立方米的焦?fàn)t煤氣。

　　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?fàn)t煤氣的主要成分包含氫氣（H?）、甲烷（CH?） 和一氧化碳（CO） 等可燃成分。由于焦?fàn)t煤氣成分復(fù)雜，尤其是焦?fàn)t煤氣里面還含有大量焦油、萘、硫化氫（H?S）、氨（NH?） 等雜質(zhì)，所以不能直接用于發(fā)電，否則會(huì)嚴(yán)重?fù)p害設(shè)備。

　　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?fàn)t煤氣發(fā)電，必須先將焦?fàn)t煤氣進(jìn)行深度凈化處理才行，對(duì)于焦?fàn)t煤氣中的焦油和萘，通常采用電捕法（高壓靜電吸附）等方式去除，防止它們冷凝附著在管道和設(shè)備內(nèi)部，造成堵塞和腐蝕。

　　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.

　　對(duì)于焦?fàn)t煤氣中的硫化氫和氨，通常采用濕法脫硫（堿性溶液化學(xué)反應(yīng)）和酸洗法（硫酸中和反應(yīng)）等技術(shù)脫除，以減輕設(shè)備腐蝕并減少燃燒時(shí)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?fàn)t煤氣經(jīng)過(guò)凈化后的潔凈焦?fàn)t煤氣，便可以作為燃料進(jìn)行發(fā)電。

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

　　焦?fàn)t煤氣熱值是決定發(fā)電機(jī)組輸出功率和效率的關(guān)鍵參數(shù)。熱值越低，產(chǎn)生同等電力所需的煤氣量就越大。焦?fàn)t煤氣的低位熱值的標(biāo)準(zhǔn)范圍大約在：

　　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?

　?。ɑ?16 - 18 MJ/Nm?）

　　(Or 16-18 MJ/Nm?)? ）

　　注：Nm? 指標(biāo)準(zhǔn)立方米，是在0°C、1標(biāo)準(zhǔn)大氣壓下的氣體體積單位。

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

　　焦?fàn)t煤氣的熱值并非固定不變，它主要由其化學(xué)成分構(gòu)成決定。如下圖所示，焦?fàn)t煤氣是一種多組分混合氣體，其中既包含氫氣、甲烷等高熱值可燃成分，也含有大量不可燃的惰性成分，這種獨(dú)特的組成決定了其最終的熱值水平。

　　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.

　　The main components and calorific value of coke oven gas

　　總之，焦?fàn)t煤氣熱值主要得益于氫氣和甲烷的含量，但被高比例的不可燃惰性氣體所稀釋。在利用其發(fā)電或作為燃料時(shí)，必須充分考慮其熱值特點(diǎn)，并針對(duì)其成分波動(dòng)性進(jìn)行相應(yīng)的設(shè)備設(shè)計(jì)和運(yùn)行調(diào)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.
