焦化厂有两套发电逻辑——焦炉煤气发电和干熄焦余热发电。技术路线完全不同，选型也各有一本账。

The coking plant has two sets of power generation logic - coke oven gas power generation and dry quenching coke waste heat power generation. The technical routes are completely different, and each has its own account for selection.

焦炉煤气发电——把“废气”变“电力”

Coke oven gas power generation - turning "waste gas" into "electricity"

炼焦过程产生的焦炉煤气，含有大量荒煤气显热资源。通过焦炉煤气锅炉产生蒸汽，驱动汽轮榴莲视频在线观看污发电。这条路线用的是蒸汽轮机发电系统，燃料不是煤气直接烧内燃机，而是“煤气烧锅炉→蒸汽推汽机→发电”。

The coke oven gas produced during the coking process contains a large amount of raw gas sensible heat resources. Steam is generated through a coke oven gas boiler to drive a steam turbine generator set for power generation. This route uses a steam turbine power generation system, and the fuel is not directly burned by gas to the internal combustion engine, but rather "gas burning boiler → steam pushing turbine → power generation".

干熄焦余热发电——把“红焦显热”变“电力”

Dry quenching waste heat power generation - turning "red coke sensible heat" into "electricity"

干熄焦过程用氮气冷却红焦，热氮气进入余热锅炉产生蒸汽，驱动汽轮榴莲视频在线观看污发电。干熄焦余热锅炉内部设置多级受热面，回收红焦显热。

The dry quenching process uses nitrogen to cool the red coke, and the hot nitrogen enters the waste heat boiler to generate steam, which drives the steam turbine generator set to generate electricity. Multiple heating surfaces are installed inside the dry quenching waste heat boiler to recover the sensible heat from the red coke.

两套系统可以“耦合”——效率更高

Two systems can be 'coupled' - higher efficiency

行业前沿技术是将焦炉煤气锅炉和干熄焦余热锅炉热力系统集成：干熄焦余热锅炉的高温段过热器兼做焦炉煤气锅炉蒸汽在高压缸做功后的再热器，不增设明显换热面就实现了蒸汽再热，不仅提高整套发电系统热效率，还改善了汽轮机末级叶片的工作条件。唐山港陆钢铁焦电相结合项目采用第三代环保快捷焦电联产技术，每吨焦炭发电量达1200度，发电效率比第二代技术提高20%，月发电1.4亿度。

The cutting-edge technology in the industry is to integrate the thermal systems of coke oven gas boilers and dry quenching waste heat boilers: the high-temperature section superheater of the dry quenching waste heat boiler also serves as the reheater for the steam of the coke oven gas boiler after the high-pressure cylinder works, achieving steam reheating without adding any heat exchange surface. This not only improves the thermal efficiency of the entire power generation system, but also improves the working conditions of the last stage blades of the steam turbine. The Tangshan Port Land Steel Coking Power Integration Project adopts the third-generation environmentally friendly and efficient coking power co production technology, with a power generation capacity of 1200 kWh per ton of coke, a 20% increase in power generation efficiency compared to the second-generation technology, and a monthly power generation of 140 million kWh.

焦化厂怎么选？

How to choose a coking plant?

焦炉煤气资源富余 → 焦炉煤气发电系统

Excess coke oven gas resources → Coke oven gas power generation system

干熄焦装置已配套 → 干熄焦余热发电系统

The dry quenching device has been equipped → dry quenching waste heat power generation system

大型焦化厂 → 两套系统耦合，把荒煤气显热、红焦显热、废烟气显热“三大部分余热”全回收，实现能量非常大化利用

Large coking plant → coupling two systems to fully recover the three major waste heat components of raw gas sensible heat, red coke sensible heat, and waste gas sensible heat, achieving maximum energy utilization
