1、 Relevant technologies for the application of coke oven gas power generation

焦爐煤氣是在隔絕空氣條件下高溫焦化製取焦炭的副產品。每噸川得煤氣300-350m3， 中國鋼鐵工業的快速發展加大了對焦炭的需求。國內鋼鐵工業直保持快速增長的態勢，粗鋼產量平均以每年7.59%的速度上升。鋼鐵行業的高速增長，直接結果就是焦炭需求持續大幅度增加，煤礦及鋼鐵行業副產煤氣(焦爐

Coke oven gas is a byproduct of high-temperature coking to produce coke under isolated air conditions. The rapid development of China's steel industry has increased the demand for coke by 300-350m3 per ton of Chuande gas. The domestic steel industry has maintained a rapid growth trend, with crude steel production increasing at an average annual rate of 7.59%. The rapid growth of the steel industry has directly resulted in a sustained and significant increase in demand for coke, as well as the by-product gas (coke oven) in the coal and steel industries

煤氣、高爐煤氣、轉爐煤氣)回收利用潛力很大。合理、、無汙染地利用焦爐煤氣發電和供熱，能達到節能、增效和環保的多重效果，是焦化廠多餘焦化煤氣的利用方式。

There is great potential for the recycling and utilization of gas, blast furnace gas, and converter gas. The rational, efficient, and pollution-free use of coke oven gas for power generation and heating can achieve multiple effects of energy conservation, efficiency enhancement, and environmental protection. It is the best way to utilize excess coke oven gas in coking plants.

1、燃氣發電技術應用形式

●利用燃氣內燃機好色先生在线观看發電。主要應用在單機功率3000kW以下的中小型發電設備，其優點是:

Utilize gas internal combustion engine generator sets to generate electricity. Mainly used in small and medium-sized power generation equipment with a single machine power below 3000kW, its advantages are:

①發電效率高。通常在32-40%，若增加熱電冷聯供係統，熱電效率可達80%以上。

① High power generation efficiency. Usually between 32% and 40%, if a cogeneration system is added, the thermoelectric efficiency can reach over 80%.

②造價相對較低。由於內燃機技術成熟，零件的精密度要求相對較低，單位千瓦造價低於燃氣輪機。

② The cost is relatively low. Due to the mature technology of internal combustion engines, the precision requirements for parts are relatively low, and the cost per kilowatt is lower than that of gas turbines.

③使用場合靈活。根據不同場合用戶的需要，可方便的並機或並網，構成總輸出功率達上萬千瓦的電站或

③ Flexible usage scenarioses. According to the needs of users in different occasions, it can be conveniently connected or connected to the grid, forming a power station with a total output power of tens of thousands of kilowatts

熱電冷聯供機組。機組群還可根據實際負載的需要，靈活方便地調節發電輸出。

A cogeneration unit of heat, electricity, and cooling. The unit group can also flexibly and conveniently adjust the power generation output according to the actual load needs.

④可以使用多種低熱值燃氣，應用範圍廣。

④ Multiple types of low calorific value gas can be used, with a wide range of applications.

⑤調峰性能更好，啟停方便快捷。

⑤ Peak shaving performance is the best, with convenient and fast start and stop.

⑥維修簡單，安裝方便。設備體積小，重量輕，大修周期長、維修簡單。缺點主要是單機功率較小，不能適用於大規模的發電的需要。

⑥ Easy maintenance and easy installation. The equipment has small size, light weight, long overhaul cycle, and simple maintenance. The main drawback is that the single machine power is small and cannot be suitable for large-scale power generation needs.

總之，燃氣內燃機發電技術成熟，工藝穩定，投資小，見效快，運行維護相對簡單，適用於多種行業。

In short, the gas internal combustion engine power generation technology is mature, the process is stable, the investment is small, the efficiency is fast, the operation and maintenance are relatively simple, and it is suitable for various industries.

2、焦爐煤氣發電對燃氣好色先生在线观看的特殊技術要求

2. Special technical requirements for gas generator sets for coke oven gas power generation

焦爐煤氣組分中含氫氣47-60% (體積)、甲烷23-27%、-氧化碳6-8%等。焦爐煤氣的發熱值約為

The composition of coke oven gas contains 47% -60% hydrogen (volume), 23% -27% methane, and 6% -8% carbon oxide. The heating value of coke oven gas is approximately

15-16.8MJ/Nm3，可用來發電。但一般的燃氣機一 天然 氣或煤層氣發動機不能直接用於焦爐煤氣,燃氣機

15-16.8MJ/Nm3, can be used for power generation. But ordinary gas engines such as natural gas or coalbed methane engines cannot be directly used for coke oven gas

必須進行適用焦爐煤氣特性的改造，解決焦爐煤氣含氫比例高、爆炸極限範圍寬(4.1-74.2%)， 其氣體組份和濃度動態變化大，混合氣的空燃比動態變化大，燃燒速度快而帶來的屐轉速和輸出功率不穩定，波動大問題。

It is necessary to carry out modifications that are suitable for the characteristics of coke oven gas, in order to solve the problems of high hydrogen content and wide explosion limit range (4.1-74.2%) of coke oven gas, large dynamic changes in gas composition and concentration, large dynamic changes in air fuel ratio of mixed gas, and unstable and fluctuating speed and output power caused by fast combustion speed.
