　　Waste gas turns into green electricity! 180000 kW Huanneng brand mineral heat furnace gas generator set, with full cycle power generation efficiency, saving millions of costs annually

　　做冶金、礦熱爐生產(chǎn)的老板們，是不是都有同一個煩惱：礦熱爐生產(chǎn)過程中，會產(chǎn)生大量高爐煤氣、焦?fàn)t煤氣，以前大多是直接點燃排空，俗稱“點天燈”，不僅浪費寶貴的能源，還會污染環(huán)境，環(huán)保檢查過不了，每年還要花不少錢處理廢氣；而廠區(qū)生產(chǎn)又需要大量電力，外購電價居高不下，大大增加了生產(chǎn)成本。今天就給大家嘮個“變廢為寶”的硬核設(shè)備——礦熱爐煤氣發(fā)電機組，以能源動力總廠阿爾法電三廠180000kW（18萬kW）環(huán)能牌機組為例，用大白話+實操原理+實打?qū)嵉臄?shù)據(jù)，把它的循環(huán)發(fā)電邏輯講透，既環(huán)保又省電，助力企業(yè)降本增效，看完就知道它有多香。

　　Bosses in metallurgy and mineral heat furnace production all have the same problem: during the production process of mineral heat furnaces, a large amount of blast furnace gas and coke oven gas are generated. In the past, most of them were directly ignited and discharged, commonly known as "lighting sky lanterns". This not only wastes valuable energy but also pollutes the environment. Environmental inspections cannot be passed, and a considerable amount of money is spent every year to treat waste gas; However, the production in the factory requires a large amount of electricity, and the high external electricity prices greatly increase production costs. Today, we will talk about a hardcore equipment that can turn waste into treasure - the mineral heat furnace gas generator set. Taking the 180000 kW (180000 kW) environmental energy brand unit of Alpha Power Plant as an example, we will explain its cycle power generation logic in plain language, practical principles, and actual data. It is both environmentally friendly and energy-saving, helping enterprises reduce costs and increase efficiency. After reading it, you will know how delicious it is.

　　先給大家上一組硬數(shù)據(jù)，直觀感受環(huán)能牌機組的實力：這款18萬kW環(huán)能牌礦熱爐煤氣發(fā)電機組，專門適配冶金行業(yè)礦熱爐廢氣回收發(fā)電，每天可處理高爐煤氣、焦?fàn)t煤氣約48萬立方米，相當(dāng)于每小時處理2萬立方米廢氣，年發(fā)電量可達10.6億千瓦時，能滿足一座中型冶金廠區(qū)80%以上的用電需求，每年可節(jié)省外購電費超5億元，同時年減少二氧化碳排放85.4萬噸，既解決了廢氣污染難題，又實現(xiàn)了能源循環(huán)利用，妥妥的“環(huán)保+節(jié)能”雙標(biāo)桿，也契合環(huán)能牌機組“余熱余氣資源化利用”的核心定位。

　　First, let me give you a set of hard data to visually experience the strength of the Huaneng brand unit: this 180000 kW Huaneng brand mineral heat furnace gas generator set is specially adapted to the metallurgical industry's mineral heat furnace waste gas recovery and power generation. It can process about 480000 cubic meters of blast furnace gas and coke oven gas per day, equivalent to processing 20000 cubic meters of waste gas per hour. The annual power generation can reach 1.06 billion kilowatt hours, which can meet more than 80% of the electricity demand of a medium-sized metallurgical plant area. It can save over 500 million yuan in purchased electricity costs annually and reduce 854000 tons of carbon dioxide emissions annually. It not only solves the problem of waste gas pollution, but also achieves energy recycling, which is a perfect "environmental protection+energy conservation" dual benchmark and also fits the Huaneng brand unit's "waste heat and gas resources". The core positioning of "utilization".

　　很多老板好奇，環(huán)能牌礦熱爐煤氣發(fā)電機組到底是怎么工作的？其實原理并不復(fù)雜，核心就是“回收廢氣、循環(huán)發(fā)電”，全程閉環(huán)運行，不浪費一點能源，結(jié)合阿爾法電三廠的環(huán)能牌機組實操，給大家拆解明白，一看就懂——它和普通發(fā)電機組最大的區(qū)別，就是不用專門消耗燃料，而是“吃”礦熱爐產(chǎn)生的廢氣，比如鞍鋼的高爐煤氣，再搭配少量焦?fàn)t煤氣回?zé)瑢崿F(xiàn)“變廢為寶”，這也是環(huán)能牌機組在工業(yè)尾氣利用領(lǐng)域的核心優(yōu)勢。

　　Many bosses are curious about how the Huanneng brand mineral heat furnace gas generator set works? In fact, the principle is not complicated. The core is "recycling waste gas and circulating power generation", which operates in a closed loop throughout the process without wasting any energy. Combined with the practical operation of the Alpha Power Plant's environmental energy brand unit, it can be disassembled and understood at a glance. The biggest difference between it and ordinary power generation units is that it does not specifically consume fuel, but "eats" the waste gas generated by mineral thermal furnaces, such as Ansteel's blast furnace gas, and then burns it back with a small amount of coke oven gas to achieve "turning waste into treasure". This is also the core advantage of environmental energy brand units in the field of industrial exhaust gas utilization.

　　第一步，煤氣收集與升壓，筑牢發(fā)電基礎(chǔ)。礦熱爐生產(chǎn)過程中產(chǎn)生的高爐煤氣（熱值約3500kJ/m?）、焦?fàn)t煤氣（熱值約17000kJ/m?），會先通過專用管道收集起來，避免泄漏污染環(huán)境，收集效率達99.5%以上；隨后送入煤氣壓縮機，將煤氣壓力從0.1MPa升壓至1.2MPa，確保煤氣能穩(wěn)定進入燃燒室——這一步是發(fā)電的關(guān)鍵，壓力不穩(wěn)定會直接影響發(fā)電效率，而這款18萬kW環(huán)能牌機組的壓縮機，穩(wěn)定性達99.8%，全年故障停機時間不超過8小時，遠超環(huán)能牌常規(guī)機組“年運行超8000小時”的基礎(chǔ)標(biāo)準(zhǔn)。

　　The first step is to collect and boost the gas, laying a solid foundation for power generation. The blast furnace gas (with a calorific value of about 3500kJ/m ?) and coke oven gas (with a calorific value of about 17000kJ/m ?) generated during the production process of the ore blast furnace will be collected through dedicated pipelines to avoid leakage and environmental pollution, with a collection efficiency of over 99.5%; Then it is sent to the gas compressor to increase the gas pressure from 0.1MPa to 1.2MPa, ensuring that the gas can enter the combustion chamber stably - this step is the key to power generation. Unstable pressure will directly affect power generation efficiency. The compressor of this 180000 kW Huanneng brand unit has a stability of 99.8%, and the annual shutdown time for faults does not exceed 8 hours, far exceeding the basic standard of "over 8000 hours of annual operation" for Huanneng brand conventional units.

　　第二步，燃氣燃燒產(chǎn)能，驅(qū)動燃機發(fā)電。升壓后的混合煤氣，送入燃氣燃燒室，與空氣充分混合后點燃，產(chǎn)生溫度高達1300-1500℃、壓力1.0-1.5MPa的高溫高壓燃氣，這些燃氣會推動燃機轉(zhuǎn)子高速旋轉(zhuǎn)，轉(zhuǎn)速可達3000r/min，進而帶動燃機自帶的發(fā)電機運轉(zhuǎn)，將熱能轉(zhuǎn)化為電能。這一步的發(fā)電效率達43.5%，相當(dāng)于每2.3立方米高爐煤氣就能發(fā)1度電，比普通煤氣發(fā)電機組效率提升15%以上，也高于環(huán)能牌常規(guī)煤氣發(fā)電機組40%的平均能效，充分體現(xiàn)了其大功率機型的性能優(yōu)勢。

　　The second step is to increase the production capacity of gas combustion and drive the gas turbine to generate electricity. The pressurized mixed gas is sent into the gas combustion chamber, fully mixed with air, and ignited to produce high-temperature and high-pressure gas with a temperature of up to 1300-1500 ℃ and a pressure of 1.0-1.5MPa. These gases will drive the high-speed rotation of the gas turbine rotor, with a speed of up to 3000r/min, and then drive the built-in generator of the gas turbine to convert thermal energy into electrical energy. The power generation efficiency of this step reaches 43.5%, equivalent to generating 1 kWh of electricity for every 2.3 cubic meters of blast furnace gas, which is more than 15% higher than the efficiency of ordinary gas generators and also higher than the average energy efficiency of 40% of conventional gas generators from Huanneng brand, fully reflecting the performance advantages of its high-power models.

　　第三步，余熱回收再利用，實現(xiàn)循環(huán)發(fā)電，這也是環(huán)能牌機組最核心的亮點，很多普通發(fā)電機組都做不到，更是環(huán)能牌在余熱余氣資源化利用領(lǐng)域的核心技術(shù)體現(xiàn)。燃氣在燃機內(nèi)做功后，尾部會排出溫度約550-600℃的熱氣，這些熱氣并沒有被浪費，而是通過管道導(dǎo)入余熱鍋爐——這里要重點說一句，余熱鍋爐不用燒火，全程靠燃機排出的廢氣供熱，徹底區(qū)別于傳統(tǒng)鍋爐，節(jié)能又環(huán)保，也契合環(huán)能牌機組低耗、環(huán)保的產(chǎn)品特性。

　　The third step is to recover and reuse waste heat to achieve circular power generation, which is also the core highlight of Huanneng brand units. Many ordinary generator units cannot achieve this, and it is also the core technology embodiment of Huanneng brand in the field of waste heat and gas resource utilization. After the gas does work in the gas turbine, the tail will discharge hot gas with a temperature of about 550-600 ℃. These hot gases are not wasted, but are introduced into the waste heat boiler through pipelines. Here, it should be emphasized that the waste heat boiler does not need to ignite, and relies on the exhaust gas discharged from the gas turbine to provide heat throughout the process. It is completely different from traditional boilers, energy-saving and environmentally friendly, and also in line with the low consumption and environmentally friendly product characteristics of the Huanneng brand unit.

　　余熱鍋爐內(nèi)裝有專用換熱模塊，模塊中的給水會被燃機廢氣加熱，加熱至450℃、壓力10MPa以上，形成高溫高壓蒸汽，這些蒸汽會輸送至上方的汽包（用戶口中的“細胞”），汽包對蒸汽進行分離凈化后，再將潔凈蒸汽反射輸送回蒸汽輪機；蒸汽輪機被高溫高壓蒸汽驅(qū)動旋轉(zhuǎn)，進而帶動另一臺發(fā)電機發(fā)電，完成第二次能量轉(zhuǎn)化，這一步可額外提升發(fā)電效率10%-15%，讓整個發(fā)電過程形成閉環(huán)，也讓環(huán)能牌機組的能源回收效率高達90%以上，遠超行業(yè)平均水平。

　　The waste heat boiler is equipped with a dedicated heat exchange module, and the feedwater in the module will be heated by the exhaust gas of the gas turbine to 450 ℃ and a pressure of over 10MPa, forming high-temperature and high-pressure steam. These steam will be transported to the upper steam drum (the "cells" in the user's household), which separates and purifies the steam, and then reflects and transports the clean steam back to the steam turbine; The steam turbine is driven to rotate by high-temperature and high-pressure steam, which in turn drives another generator to generate electricity and complete the second energy conversion. This step can increase the power generation efficiency by an additional 10% -15%, forming a closed loop in the entire power generation process. It also enables the energy recovery efficiency of Huanneng brand units to reach over 90%, far exceeding the industry average level.

　　補充一組實用數(shù)據(jù)，方便老板們參考：這款18萬kW環(huán)能牌礦熱爐煤氣發(fā)電機組，整機占地面積約800㎡，適配30MVA及以上礦熱爐的廢氣處理需求，機組運行時噪聲控制在75-85dB（A），符合工業(yè)廠區(qū)噪聲標(biāo)準(zhǔn)，相較于環(huán)能牌常規(guī)機組≤75dB（A）的噪聲標(biāo)準(zhǔn)，更適配大型冶金廠區(qū)的生產(chǎn)場景；每年可回收利用廢氣約1.75億立方米，減少廢氣排放1.75億立方米，相當(dāng)于每年少燒50萬噸標(biāo)準(zhǔn)煤，環(huán)保效益突出，排放達國六標(biāo)準(zhǔn)，可輕松通過環(huán)保驗收，也彰顯了環(huán)能牌機組的環(huán)保實力。

　　Add a set of practical data for the convenience of bosses to refer to: This 180000 kW Huaneng brand mineral heat furnace gas generator set covers an area of about 800 square meters and is suitable for the exhaust gas treatment needs of mineral heat furnaces of 30MVA and above. The noise control of the unit during operation is between 75-85dB (A), which meets the noise standard of industrial plants. Compared with the noise standard of Huaneng brand conventional units ≤ 75dB (A), it is more suitable for production scenarios in large metallurgical plants; Approximately 175 million cubic meters of waste gas can be recycled annually, reducing emissions by 175 million cubic meters, which is equivalent to burning 500000 tons of standard coal less per year. The environmental benefits are outstanding, with emissions meeting the National VI standard. It can easily pass environmental inspections and also demonstrates the environmental strength of the Huanneng brand units.

　　從成本角度來說，環(huán)能牌機組的優(yōu)勢更明顯：以前礦熱爐廢氣“點天燈”，每年不僅浪費能源，還需投入約50萬元廢氣處理費；而使用這款環(huán)能牌發(fā)電機組，每年可發(fā)電10.6億千瓦時，按工業(yè)用電0.5元/度計算，年發(fā)電收益達5.3億元，扣除機組運維成本（每年約800萬元），每年可凈省成本超5億元，投資回報率極高，一般3-4年就能收回設(shè)備投資，相較于普通機組，環(huán)能牌機組因運維間隔≥1000小時，后期運維成本可額外節(jié)省10%以上。

　　From a cost perspective, the advantages of the Huanneng brand unit are more obvious: in the past, the waste gas from the ore blast furnace was "lit up", which not only wasted energy but also required an investment of about 500000 yuan in waste gas treatment fees every year; By using this Huanneng brand generator set, it can generate 1.06 billion kilowatt hours of electricity annually. Calculated at an industrial electricity consumption of 0.5 yuan/kWh, the annual power generation revenue reaches 530 million yuan. After deducting the unit operation and maintenance costs (about 8 million yuan per year), the net cost savings can exceed 500 million yuan per year. The investment return rate is extremely high, and the equipment investment can generally be recovered in 3-4 years. Compared with ordinary units, Huanneng brand units can save more than 10% of later operation and maintenance costs due to operation and maintenance intervals of ≥ 1000 hours.

　　而且環(huán)能牌機組操作簡單，采用全自動PLC控制系統(tǒng)，1人可監(jiān)管多臺機組，實現(xiàn)“無人干預(yù)、少人值守”，每年可節(jié)省人工成本約60萬元；機組使用壽命可達20年，遠超環(huán)能牌常規(guī)機組10年以上的使用壽命，每年運維成本僅占總投資的1.5%左右，后期維護省心，不用投入大量人力物力，也體現(xiàn)了環(huán)能牌機組穩(wěn)定、耐用的產(chǎn)品特質(zhì)。

　　Moreover, the Huanneng brand unit is easy to operate and adopts a fully automatic PLC control system. One person can supervise multiple units, achieving "unmanned intervention and few people on duty", which can save labor costs of about 600000 yuan per year; The service life of the unit can reach 20 years, far exceeding the service life of conventional units of Huanneng brand by more than 10 years. The annual operation and maintenance cost only accounts for about 1.5% of the total investment. The later maintenance is worry free and does not require a lot of manpower and material resources, which also reflects the stable and durable product characteristics of Huanneng brand units.

　　總結(jié)來說，礦熱爐煤氣發(fā)電機組，尤其是環(huán)能牌18萬kW大功率機型，是冶金、礦熱爐企業(yè)的“節(jié)能神器”“環(huán)保救星”，也是環(huán)能牌在余熱余氣資源化利用領(lǐng)域的標(biāo)桿產(chǎn)品。它以礦熱爐廢氣為原料，通過“煤氣升壓→燃機發(fā)電→余熱回收→蒸汽輪機再發(fā)電”的閉環(huán)流程，實現(xiàn)廢氣變綠電，既解決了廢氣污染難題，又能自給自足供電，大幅降低外購電費，助力企業(yè)降本增效、綠色發(fā)展。不管你是大型冶金廠區(qū)，還是中型礦熱爐生產(chǎn)企業(yè)，這款環(huán)能牌礦熱爐煤氣發(fā)電機組，都能完美適配你的需求，依托其穩(wěn)定、高效、環(huán)保的優(yōu)勢，讓“環(huán)保包袱”變成“價值引擎”。

　　In summary, the coal gas generator set of the blast furnace, especially the 180000 kW high-power model of the Huaneng brand, is the "energy-saving artifact" and "environmental savior" of metallurgical and blast furnace enterprises, and also the benchmark product of Huaneng brand in the field of waste heat and gas resource utilization. It uses the waste gas from the ore blast furnace as raw material, and through the closed-loop process of "gas boosting → gas turbine power generation → waste heat recovery → steam turbine power generation", it realizes the transformation of waste gas into green electricity, which not only solves the problem of waste gas pollution, but also provides self-sufficient power supply, greatly reducing external electricity costs and helping enterprises reduce costs, increase efficiency, and promote green development.
