焦化發(fā)電機組以焦化過程中產(chǎn)生的煤氣為燃料進行發(fā)電，既實現(xiàn)了能源的循環(huán)利用，又降低了污染物排放，其適用場景與焦化產(chǎn)業(yè)布局、能源需求特點密切相關(guān)，尤其在工業(yè)集中區(qū)、能源消耗大戶及環(huán)保要求嚴格的區(qū)域發(fā)揮著重要作用，成為銜接焦化生產(chǎn)與能源供應(yīng)的關(guān)鍵設(shè)備。

　　Coking power generation units use coal gas generated during the coking process as fuel for power generation, which not only achieves energy recycling but also reduces pollutant emissions. Their applicability is closely related to the layout of the coking industry and the characteristics of energy demand, especially in industrial concentration areas, energy consuming households, and areas with strict environmental protection requirements, playing an important role and becoming a key equipment connecting coking production and energy supply.

　　焦化廠區(qū)內(nèi)部是焦化發(fā)電機組的核心應(yīng)用場景，能實現(xiàn)能源的高效循環(huán)利用。焦化生產(chǎn)過程中會產(chǎn)生大量焦爐煤氣（主要成分為氫氣、甲烷、一氧化碳），過去部分企業(yè)將其直接燃燒排放，不僅浪費能源，還污染環(huán)境。在廠區(qū)內(nèi)配套發(fā)電機組，可將焦爐煤氣凈化處理后作為燃料驅(qū)動機組發(fā)電，滿足廠區(qū)自身用電需求（如焦爐加熱、水泵運轉(zhuǎn)、車間照明），剩余電力還可并入廠區(qū)電網(wǎng)供其他生產(chǎn)環(huán)節(jié)使用。這種 “產(chǎn)氣 - 發(fā)電 - 自用” 的模式，使焦爐煤氣利用率提升至 95% 以上，減少能源浪費的同時，降低企業(yè)外購電成本，單座中型焦化廠配套發(fā)電機組后，每年可節(jié)省電費數(shù)千萬元，且發(fā)電過程中產(chǎn)生的余熱可回收用于廠區(qū)供暖或工藝加熱，進一步提高能源綜合利用率。

　　The interior of the coking plant is the core application scenario of coking power generation units, which can achieve efficient recycling of energy. During the coking production process, a large amount of coke oven gas (mainly composed of hydrogen, methane, and carbon monoxide) is produced. In the past, some companies directly burned and emitted it, which not only wasted energy but also polluted the environment. Supporting generator sets within the factory area can purify and treat coke oven gas, which can be used as fuel to drive the unit for power generation, meeting the factory's own electricity needs (such as coke oven heating, water pump operation, workshop lighting). The remaining electricity can also be integrated into the factory's power grid for use in other production processes. This "gas production power generation self use" model increases the utilization rate of coke oven gas to over 95%, reduces energy waste, and lowers the cost of purchasing electricity for enterprises. After a single medium-sized coking plant is equipped with a generator set, it can save tens of millions of yuan in electricity bills every year, and the waste heat generated during the power generation process can be recovered for plant heating or process heating, further improving the comprehensive energy utilization rate.

　　工業(yè)園區(qū)內(nèi)的集中供電系統(tǒng)適合引入焦化發(fā)電機組，為區(qū)域工業(yè)生產(chǎn)提供穩(wěn)定電源。許多焦化廠位于綜合性工業(yè)園區(qū)內(nèi)，周邊聚集著鋼鐵、化工、建材等高耗能企業(yè)，這些企業(yè)對電力需求大且用電穩(wěn)定性要求高。將焦化發(fā)電機組與園區(qū)配電網(wǎng)連接，可作為園區(qū)的分布式電源，在電網(wǎng)供電緊張時補充電力缺口，在電價高峰時段替代外購電，降低園區(qū)整體用電成本。同時，焦化發(fā)電機組運行穩(wěn)定，發(fā)電負荷可根據(jù)園區(qū)用電需求靈活調(diào)整（負荷調(diào)節(jié)范圍通常為 50%-100%），能快速響應(yīng)用電波動，保障園區(qū)內(nèi)連續(xù)性生產(chǎn)設(shè)備（如煉鋼爐、反應(yīng)釜）的正常運行。此外，發(fā)電機組排放的尾氣經(jīng)處理后可作為部分化工企業(yè)的原料（如生產(chǎn)合成氨），形成 “發(fā)電 - 尾氣利用” 的產(chǎn)業(yè)鏈，提升園區(qū)資源循環(huán)水平。

　　The centralized power supply system in the industrial park is suitable for introducing coking generator units to provide stable power for regional industrial production. Many coking plants are located in comprehensive industrial parks, surrounded by high energy consuming enterprises such as steel, chemical, and building materials. These enterprises have a large demand for electricity and high requirements for electricity stability. Connecting the coking power generation unit to the distribution network of the park can serve as a distributed power source for the park, supplementing the power gap when the power grid is tight, replacing purchased electricity during peak electricity prices, and reducing the overall electricity cost of the park. At the same time, the coking power generation unit operates stably, and the power generation load can be flexibly adjusted according to the power demand of the park (the load adjustment range is usually 50% -100%), which can quickly respond to power fluctuations and ensure the normal operation of continuous production equipment (such as steelmaking furnaces and reactors) in the park. In addition, the exhaust gas emitted by the generator set can be treated and used as raw materials for some chemical enterprises (such as producing synthetic ammonia), forming an industrial chain of "power generation exhaust gas utilization" and improving the resource recycling level of the park.

　　鋼鐵聯(lián)合企業(yè)是焦化發(fā)電機組的重要應(yīng)用對象，能實現(xiàn)多產(chǎn)業(yè)協(xié)同增效。鋼鐵生產(chǎn)中，焦化環(huán)節(jié)為高爐煉鐵提供焦炭，而煉鐵、煉鋼過程需要大量電力。在鋼鐵聯(lián)合企業(yè)內(nèi)，焦化發(fā)電機組產(chǎn)生的電力可直接供應(yīng)給煉鐵廠、煉鋼廠，減少企業(yè)對外部電網(wǎng)的依賴，尤其在電網(wǎng)故障或限電時，可作為應(yīng)急電源保障關(guān)鍵生產(chǎn)環(huán)節(jié)不中斷。同時，鋼鐵企業(yè)對焦爐煤氣的需求量大且穩(wěn)定，能保證發(fā)電機組滿負荷運行，提高發(fā)電效率（滿負荷時發(fā)電效率可達 35% 以上）。此外，發(fā)電機組的余熱可用于鋼鐵廠的熱水供應(yīng)、蒸汽生產(chǎn)，滿足軋鋼等工序的熱力需求，形成 “焦化 - 發(fā)電 - 鋼鐵” 的能源閉環(huán)，大幅降低企業(yè)綜合能耗。

　　Steel joint ventures are important application objects of coking power generation units, which can achieve multi industry synergy and efficiency improvement. In steel production, the coking process provides coke for blast furnace ironmaking, while the ironmaking and steelmaking processes require a large amount of electricity. In steel joint ventures, the electricity generated by coking power generation units can be directly supplied to ironworks and steelmaking plants, reducing the company's dependence on external power grids. Especially in the event of power grid failures or restrictions, it can serve as an emergency power source to ensure that key production processes are not interrupted. At the same time, steel companies have a large and stable demand for coke oven gas, which can ensure the full load operation of generator sets and improve power generation efficiency (the power generation efficiency can reach over 35% at full load). In addition, the waste heat from the generator set can be used for hot water supply and steam production in the steel plant, meeting the thermal needs of processes such as steel rolling, forming an energy loop of "coking power generation steel", and significantly reducing the comprehensive energy consumption of the enterprise.

　　高耗能工業(yè)園區(qū)的熱電聯(lián)產(chǎn)項目中，焦化發(fā)電機組能兼顧電力與熱力供應(yīng)。在化工、建材等產(chǎn)業(yè)集中的高耗能園區(qū)，企業(yè)不僅需要電力，還需大量蒸汽用于生產(chǎn)（如化工反應(yīng)加熱、建材烘干）。焦化發(fā)電機組可采用熱電聯(lián)產(chǎn)模式，在發(fā)電的同時，通過余熱鍋爐回收煙氣中的熱量產(chǎn)生蒸汽，蒸汽通過園區(qū)熱力管網(wǎng)輸送至各企業(yè)，滿足其熱力需求。這種模式下，能源利用率可達 70% 以上，遠高于單純發(fā)電的效率，且能減少園區(qū)內(nèi)分散鍋爐的數(shù)量，降低污染物排放總量。對于北方地區(qū)的工業(yè)園區(qū)，冬季還可利用余熱為園區(qū)內(nèi)企業(yè)及周邊生活區(qū)供暖，實現(xiàn) “電、熱、暖” 三聯(lián)供，提升能源綜合利用價值。

　　In the cogeneration project of high energy consuming industrial parks, coking generator units can balance the supply of electricity and heat. In high energy consuming industrial parks with concentrated chemical and building materials industries, enterprises not only require electricity, but also a large amount of steam for production (such as chemical reaction heating and building material drying). Coking power generation units can adopt a combined heat and power generation mode. While generating electricity, the heat in the flue gas is recovered through a waste heat boiler to produce steam. The steam is transported to various enterprises through the park's thermal pipeline network to meet their thermal needs. In this mode, the energy utilization rate can reach over 70%, which is much higher than the efficiency of simple power generation, and can reduce the number of scattered boilers in the park and lower the total amount of pollutant emissions. For industrial parks in northern regions, waste heat can also be used to provide heating for enterprises and surrounding living areas in the park during winter, realizing the "electricity, heat, and heating" triple supply and enhancing the comprehensive utilization value of energy.
