　　Gas generator set: 180000 units of gas co firing combined cycle, solving the pain point of low efficiency power generation caused by industrial exhaust gas

　　在鋼鐵行業(yè)能源循環(huán)利用體系中，高爐煤氣、焦?fàn)t煤氣作為產(chǎn)量龐大的工業(yè)副產(chǎn)尾氣，長(zhǎng)期存在粗放燃燒、能源利用率低、碳排放偏高的行業(yè)痛點(diǎn)，大量可燃尾氣未能實(shí)現(xiàn)高效轉(zhuǎn)化，既浪費(fèi)資源又加重環(huán)保壓力。而能源動(dòng)力總廠二發(fā)電分廠的**18萬(wàn)燃?xì)廨啓C(jī)組**，作為大功率聯(lián)合循環(huán)燃?xì)獍l(fā)電機(jī)組的標(biāo)桿設(shè)備，徹底顛覆傳統(tǒng)煤氣發(fā)電模式，以高爐煤氣為主、焦?fàn)t煤氣混燒的燃料結(jié)構(gòu)，搭配燃機(jī)+余熱鍋爐+蒸汽輪機(jī)聯(lián)動(dòng)工藝，實(shí)現(xiàn)工業(yè)尾氣能源“吃干榨凈”，發(fā)電效率遠(yuǎn)超常規(guī)機(jī)組，成為重工業(yè)煤氣高效利用、節(jié)能降碳的核心裝備。

　　In the energy recycling system of the steel industry, blast furnace gas and coke oven gas, as industrial by-products with large output, have long been industry pain points such as extensive combustion, low energy utilization rate, and high carbon emissions. A large amount of combustible tail gas has not been efficiently converted, which not only wastes resources but also increases environmental pressure. The 180000 yuan gas turbine unit of the Second Power Generation Branch of the Energy and Power Plant, as a benchmark equipment for high-power combined cycle gas generator units, completely subverts the traditional gas power generation mode. It uses blast furnace gas as the main fuel and coke oven gas mixed combustion fuel structure, combined with gas turbine+waste heat boiler+steam turbine linkage process, to achieve the "dry extraction" of industrial exhaust gas energy, with power generation efficiency far exceeding conventional units, becoming the core equipment for efficient utilization, energy conservation and carbon reduction of heavy industry gas.

　　全流程發(fā)電原理：聯(lián)合循環(huán)高效轉(zhuǎn)化，無(wú)能源浪費(fèi)

　　Principle of full process power generation: efficient conversion of combined cycle, no energy waste

　　整套燃?xì)獍l(fā)電機(jī)組發(fā)電流程環(huán)環(huán)相扣，遵循“煤氣升壓-燃機(jī)做功-余熱回收-蒸汽補(bǔ)功”的聯(lián)合循環(huán)邏輯，每一步都實(shí)現(xiàn)能源高效轉(zhuǎn)化，無(wú)多余熱量損耗。首先，將高爐煤氣作為主力燃料，按需摻入少量高熱值焦?fàn)t煤氣優(yōu)化燃料結(jié)構(gòu)，通過(guò)專(zhuān)用煤氣壓縮機(jī)完成升壓處理，保障氣體輸送壓力穩(wěn)定，滿(mǎn)足燃?xì)廨啓C(jī)燃燒工況要求；隨后，升壓后的混合煤氣進(jìn)入燃?xì)廨啓C(jī)燃燒室充分燃燒，產(chǎn)生高溫高壓氣流，直接驅(qū)動(dòng)燃?xì)廨啓C(jī)高速旋轉(zhuǎn)，同步帶動(dòng)燃機(jī)側(cè)發(fā)電機(jī)完成第一輪發(fā)電，這也是機(jī)組核心發(fā)電環(huán)節(jié)。

　　The entire power generation process of the gas generator set is interconnected, following the combined cycle logic of "gas boosting - gas turbine power generation - waste heat recovery - steam power replenishment", achieving efficient energy conversion at each step without excess heat loss. Firstly, blast furnace gas is used as the main fuel, and a small amount of high calorific value coke oven gas is added as needed to optimize the fuel structure. The pressure is increased through a dedicated gas compressor to ensure stable gas delivery pressure and meet the requirements of gas turbine combustion conditions; Subsequently, the boosted mixed gas enters the combustion chamber of the gas turbine for full combustion, generating high-temperature and high-pressure airflow, which directly drives the gas turbine to rotate at high speed and synchronously drives the generator on the gas turbine side to complete the first round of power generation, which is also the core power generation link of the unit.

　　燃機(jī)做功后排出的高溫尾氣，并非直接排放，而是輸送至配套余熱鍋爐，利用尾氣余熱加熱鍋爐內(nèi)部給水，余熱鍋爐無(wú)額外明火燃燒，純靠尾氣余熱換熱，將冷水逐步加熱形成高壓蒸汽，匯集至頂部汽包穩(wěn)壓儲(chǔ)能；最后，汽包輸出的高壓蒸汽回送至蒸汽輪機(jī)，推動(dòng)蒸汽輪機(jī)運(yùn)轉(zhuǎn)，帶動(dòng)蒸汽側(cè)發(fā)電機(jī)完成第二輪發(fā)電，通過(guò)燃?xì)庋h(huán)、蒸汽循環(huán)雙重做功，實(shí)現(xiàn)聯(lián)合循環(huán)高效發(fā)電，大幅提升整體能源利用率。

　　The high-temperature exhaust gas discharged from the gas turbine after doing work is not directly discharged, but is transported to the supporting waste heat boiler, which uses the waste heat of the exhaust gas to heat the internal water supply of the boiler. The waste heat boiler does not have additional open flame combustion, and relies solely on the heat exchange of the exhaust gas waste heat to gradually heat the cold water into high-pressure steam, which is collected in the top steam drum for stable energy storage; Finally, the high-pressure steam output from the steam drum is sent back to the steam turbine, which drives the steam turbine to operate and drives the steam side generator to complete the second round of power generation. Through the dual work of the gas cycle and steam cycle, efficient combined cycle power generation is achieved, greatly improving the overall energy utilization efficiency.
