焦化發電機組的安裝有利于帶動區域經濟發展，變輸煤為輸電，實現多能互補轉化。200萬噸/年循環經濟綜合利用煤焦化項目以精煤為原料，通過焦爐煤氣深加工循環利用、焦炭余熱回收循環利用、焦爐煙氣余熱綜合循環利用、焦化廢水處理中水回用、煤氣中硫及脫硫廢液循環再利用，提高煤炭資源利用率，實現資源精深加工目的。

The installation of coking power generation units is conducive to driving regional economic development, transforming coal transportation into power transmission, and achieving multi energy complementary conversion. The 2 million tons/year circular economy comprehensive utilization coal coking project uses clean coal as raw material, and through deep processing and recycling of coke oven gas, recovery and recycling of coke waste heat, comprehensive recycling of coke oven flue gas waste heat, reuse of coking wastewater treatment water, and recycling of sulfur and desulfurization waste liquid in gas, improves the utilization rate of coal resources and achieves the goal of deep processing of resources.

1.焦化發電機組工作原理：

1. Working principle of coking generator set:

（1）壓縮式氣化工藝（簡稱壓氣化）：

(1) Compression gasification process (referred to as compressed gasification):

壓氣化是利用焦爐排出的煤氣加熱汽輪機凝汽器中的飽和蒸汽而獲得能量的方法。

Pressure gasification is a method of obtaining energy by heating saturated steam in the condenser of a steam turbine using gas discharged from a coke oven.

（2）直接燃燒式氣化工藝（簡稱直燃法）：

(2) Direct combustion gasification process (referred to as direct combustion method):

直燃法是采用煤粉作原料的燃氣發生技術，其基本原理是在一定的壓力下將燃料噴入爐膛內進行氧化反應生成可燃氣體和助燃空氣的燃燒過程。

Direct combustion method is a gas generation technology that uses coal powder as raw material. Its basic principle is to inject fuel into the furnace under a certain pressure for oxidation reaction to generate combustible gas and combustion supporting air.

（3）間接燃燒式氣化工藝（簡稱半干法）：

(3) Indirect combustion gasification process (referred to as semi dry method):

半干法的特點是利用部分煤氣與空氣進行化學反應產生可燃氣的過程稱為半干法轉化過程。

The characteristic of the semi dry process is that it utilizes a chemical reaction between some coal gas and air to produce combustible gas, which is called the semi dry conversion process.

2.焦化發電機組可能會遇到進水的問題。溫馨提示，焦化發電機組進水后是不能繼續使用的，因為水是無法被壓縮的，油水混合進入到汽缸后，發動機依然還牌調整運轉期間，做功的過程中不能對水進行壓縮，從而導致活塞卡死，汽缸磨損情況會變得加劇，如果焦化發電機組中有水，除了會導致焦化發電機組發電機組運轉緩慢且不穩定之外，甚至還可能造成曲軸彎曲等，對焦化發電機組發電機組的正常運行帶來非常嚴重的影響。

2. Coking power generation units may encounter water ingress issues. Kind reminder, once the coking generator unit is filled with water, it cannot continue to be used because water cannot be compressed. After the oil-water mixture enters the cylinder, the engine still needs to be adjusted during operation. During the process of doing work, the water cannot be compressed, which can cause the piston to get stuck and the cylinder wear to worsen. If there is water in the coking generator unit, in addition to causing slow and unstable operation, it may even cause crankshaft bending, which has a very serious impact on the normal operation of the coking generator unit.

解決方法：　一般發生焦化發電機組發電機組焦化發電機組進水后，要盡快把電瓶負極線拆下來，以免焦化發電機組發電機的控制系統因時水而發生短路，同時按正確步驟更換燃油濾清器，如果焦化發電機組進水不是很多，可以先讓焦化發電機組靜置一段時間，讓水慢慢沉淀下去，等到水和焦化發電機組成分層后，再將水排凈即可，而如果是進水的量比較大，則應將原有的變質焦化發電機組全部更換，否則可能會造成機組運行冒白煙或運行無力。

Solution: Generally, when water enters the coking generator set, the negative electrode wire of the battery should be removed as soon as possible to prevent the control system of the coking generator set from short circuiting due to water ingress. At the same time, the fuel filter should be replaced according to the correct steps. If there is not a lot of water ingress into the coking generator set, it can be left to settle for a period of time. After the water and coking generator form a layer, the water can be drained completely. If the amount of water ingress is relatively large, all the original deteriorated coking generator sets should be replaced, otherwise it may cause white smoke or weak operation of the unit.
