在能源利用的復雜版圖中，焦化行業長期面臨著如何高效處理生產過程中產生的大量副產煤氣的難題。焦化發電機組的出現，宛如一把鑰匙，開啟了焦化企業能源綜合利用的新大門，為行業帶來了顯著的經濟效益與環境效益。?

In the complex landscape of energy utilization, the coking industry has long faced the challenge of how to efficiently handle the large amount of by-product gas generated during the production process. The emergence of coking power generation units is like a key, opening a new door for comprehensive energy utilization in coking enterprises and bringing significant economic and environmental benefits to the industry. ?

工作原理：能量轉化的精密運作?

Working principle: Precise operation of energy conversion

焦化發電機組的核心工作基于內燃機原理，將焦化過程中產生的煤氣作為燃料，實現從化學能到電能的轉換。在焦化生產中，煤炭經過高溫干餾，產生大量的煤氣，其主要成分包含氫氣、甲烷、一氧化碳等可燃氣體。這些煤氣被收集并輸送至發電機組的內燃機系統。?

The core work of coking power generation units is based on the principle of internal combustion engines, which use the gas generated during the coking process as fuel to achieve the conversion from chemical energy to electrical energy. In coking production, coal undergoes high-temperature carbonization to produce a large amount of gas, whose main components include hydrogen, methane, carbon monoxide and other combustible gases. These gases are collected and transported to the internal combustion engine system of the generator set. ?

在內燃機的燃燒室內，煤氣與適量的空氣充分混合。當混合氣體被壓縮到一定程度后，火花塞點火引發劇烈燃燒。燃燒釋放出的巨大能量推動活塞往復運動，通過連桿帶動曲軸旋轉，從而將煤氣的化學能轉化為機械能。曲軸的持續轉動進而驅動發電機運轉，發電機內部的電磁感應裝置在旋轉過程中產生電流，實現了從機械能到電能的高效轉換。?

In the combustion chamber of an internal combustion engine, gas is thoroughly mixed with an appropriate amount of air. When the mixed gas is compressed to a certain extent, the spark plug ignites and triggers intense combustion. The enormous energy released by combustion drives the piston to reciprocate, and through the connecting rod, drives the crankshaft to rotate, thereby converting the chemical energy of coal gas into mechanical energy. The continuous rotation of the crankshaft drives the operation of the generator, and the electromagnetic induction device inside the generator generates current during the rotation process, achieving efficient conversion from mechanical energy to electrical energy. ?

為了確保燃燒過程的高效與穩定，焦化發電機組配備了先進的控制系統。該系統實時監測煤氣的流量、壓力、成分以及內燃機的運行參數，如溫度、轉速等。通過對這些數據的精確分析，控制系統能夠自動調節煤氣與空氣的混合比例、點火時機等關鍵參數，使內燃機始終保持在最佳工作狀態，提高能源轉換效率。?

In order to ensure the efficiency and stability of the combustion process, the coking generator unit is equipped with an advanced control system. The system monitors the flow rate, pressure, composition of gas in real-time, as well as the operating parameters of the internal combustion engine, such as temperature, speed, etc. Through precise analysis of these data, the control system can automatically adjust key parameters such as the mixing ratio of gas and air, ignition timing, etc., to keep the internal combustion engine in the optimal working state and improve energy conversion efficiency. ?

煤氣預處理系統?

Gas pretreatment system

煤氣預處理系統是焦化發電機組的重要前端環節。由于從焦化爐產生的煤氣中含有焦油、粉塵、硫化氫等雜質，這些雜質若直接進入發電機組，會對內燃機造成嚴重損害，影響設備壽命和發電效率。因此，煤氣預處理系統通過一系列工藝，如冷凝、過濾、脫硫等，對煤氣進行凈化處理。?

The gas pretreatment system is an important front-end link of coking power generation units. Due to the presence of impurities such as tar, dust, and hydrogen sulfide in the gas produced from coking furnaces, if these impurities directly enter the generator set, they can cause serious damage to the internal combustion engine, affecting equipment life and power generation efficiency. Therefore, the gas pretreatment system purifies the gas through a series of processes such as condensation, filtration, desulfurization, etc. ?

在冷凝環節，利用冷卻裝置將煤氣溫度降低，使其中的焦油等重質成分凝結成液態，通過分離器將其與煤氣分離。隨后，煤氣經過多級過濾裝置，去除其中的粉塵顆粒，確保煤氣的清潔度。脫硫工藝則采用化學或物理方法，脫除煤氣中的硫化氫等含硫化合物，減少燃燒過程中二氧化硫等有害氣體的排放，既保護了設備，又符合環保要求。

In the condensation process, a cooling device is used to lower the temperature of the gas, causing heavy components such as tar to condense into liquid form, which is separated from the gas through a separator. Subsequently, the gas passes through a multi-stage filtration device to remove dust particles and ensure the cleanliness of the gas. The desulfurization process uses chemical or physical methods to remove sulfur-containing compounds such as hydrogen sulfide from coal gas, reducing the emission of harmful gases such as sulfur dioxide during combustion, which not only protects equipment but also meets environmental protection requirements.

內燃機?

Internal combustion engine

內燃機是焦化發電機組的核心動力源。針對煤氣的特性，內燃機在設計上進行了專門優化。其燃燒室結構經過精心設計，以確保煤氣與空氣能夠充分混合并實現高效燃燒。同時，內燃機的活塞、連桿、曲軸等關鍵部件采用高強度、耐高溫材料制造，以承受燃燒過程中的高溫高壓沖擊，保證設備的長期穩定運行。?

Internal combustion engine is the core power source of coking generator set. The internal combustion engine has been specially optimized in design based on the characteristics of gas. The combustion chamber structure is carefully designed to ensure that the gas and air can be fully mixed and achieve efficient combustion. At the same time, key components such as pistons, connecting rods, and crankshafts of internal combustion engines are made of high-strength and high-temperature resistant materials to withstand the high temperature and high pressure impacts during combustion, ensuring the long-term stable operation of the equipment. ?

為了適應不同工況下的發電需求，內燃機還配備了先進的調速裝置。該裝置能夠根據發電機負載的變化，自動調節內燃機的轉速，確保發電機輸出電壓和頻率的穩定。此外，內燃機的潤滑系統和冷卻系統也至關重要。潤滑系統為各運動部件提供充足的潤滑油，減少摩擦損耗；冷卻系統則通過循環冷卻液帶走燃燒產生的熱量，維持內燃機的正常工作溫度。

In order to meet the power generation needs under different working conditions, internal combustion engines are also equipped with advanced speed control devices. This device can automatically adjust the speed of the internal combustion engine according to changes in the generator load, ensuring the stability of the generator output voltage and frequency. In addition, the lubrication and cooling systems of internal combustion engines are also crucial. The lubrication system provides sufficient lubricating oil for various moving parts, reducing friction losses; The cooling system uses circulating coolant to remove the heat generated by combustion and maintain the normal operating temperature of the internal combustion engine.
