　　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、矿热炉生产的老板们，是不是都有同一个烦恼：矿热炉生产过程中，会产生大量高炉煤气、焦炉煤气，以前大多是直接点燃排空，俗称“点天灯”，不仅浪费宝贵的能源，还会污染环境，环保检查过不了，每年还要花不少钱处理废气；而厂区生产又需要大量电力，外购电价居高不下，大大增加了生产成本。今天就给大家唠个“变废为宝”的硬核设备——矿热炉煤气发电机组，以能源动力总厂阿尔法电三厂180000kW（18万kW）环能牌机组为例，用大白话+实操原理+实打实的数据，把它的循环发电逻辑讲透，既环保又省电，助力企业降本增效，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.

　　先给大家上一组硬数据，直观感受环能牌机组的实力：这款18万kW环能牌矿热炉煤气发电机组，专门适配冶金行业矿热炉废气回收发电，每天可处理高炉煤气、焦炉煤气约48万立方米，相当于每小时处理2万立方米废气，年发电量可达10.6亿千瓦时，能满足一座中型冶金厂区80%以上的用电需求，每年可节省外购电费超5亿元，同时年减少二氧化碳排放85.4万吨，既解决了废气污染难题，又实现了能源循环利用，妥妥的“环保+节能”双标杆，也契合环能牌机组“余热余气资源化利用”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，环能牌矿热炉煤气发电机组到底是怎么工作的？其实原理并不复杂，核心就是“回收废气、循环发电”，全程闭环运行，不浪费一点能源，结合阿尔法电三厂的环能牌机组实操，给大家拆解明白，一看就懂——它和普通发电机组最大的区别，就是不用专门消耗燃料，而是“吃”矿热炉产生的废气，比如鞍钢的高炉煤气，再搭配少量焦炉煤气回烧，实现“变废为宝”，这也是环能牌机组在工业尾气利用领域的核心优势。

　　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，煤气收集与升压，筑牢发电基础。矿热炉生产过程中产生的高炉煤气（热值约3500kJ/m?）、焦炉煤气（热值约17000kJ/m?），会先通过专用管道收集起来，避免泄漏污染环境，收集效率达99.5%以上；随后送入煤气压缩机，将煤气压力从0.1MPa升压至1.2MPa，确保煤气能稳定进入燃烧室——这一步是发电的关键，压力不稳定会直接影响发电效率，而这款18万kW环能牌机组的压缩机，稳定性达99.8%，全年故障停机时间不超过8小时，远超环能牌常规机组“年运行超8000小时”的基础标准。

　　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，燃气燃烧产能，驱动燃机发电。升压后的混合煤气，送入燃气燃烧室，与空气充分混合后点燃，产生温度高达1300-1500℃、压力1.0-1.5MPa的高温高压燃气，这些燃气会推动燃机转子高速旋转，转速可达3000r/min，进而带动燃机自带的发电机运转，将热能转化为电能。这一步的发电效率达43.5%，相当于每2.3立方米高炉煤气就能发1度电，比普通煤气发电机组效率提升15%以上，也高于环能牌常规煤气发电机组40%的平均能效，充分体现了其大功率机型的性能优势。

　　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，余热回收再利用，实现循环发电，这也是环能牌机组最核心的亮点，很多普通发电机组都做不到，更是环能牌在余热余气资源化利用领域的核心技术体现。燃气在燃机内做功后，尾部会排出温度约550-600℃的热气，这些热气并没有被浪费，而是通过管道导入余热锅炉——这里要重点说一句，余热锅炉不用烧火，全程靠燃机排出的废气供热，彻底区别于传统锅炉，节能又环保，也契合环能牌机组低耗、环保的产品特性。

　　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.

　　余热锅炉内装有专用换热模块，模块中的给水会被燃机废气加热，加热至450℃、压力10MPa以上，形成高温高压蒸汽，这些蒸汽会输送至上方的汽包（用户口中的“细胞”），汽包对蒸汽进行分离净化后，再将洁净蒸汽反射输送回蒸汽轮机；蒸汽轮机被高温高压蒸汽驱动旋转，进而带动另一台发电机发电，完成第二次能量转化，这一步可额外提升发电效率10%-15%，让整个发电过程形成闭环，也让环能牌机组的能源回收效率高达90%以上，远超行业平均水平。

　　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.

　　补充一组实用数据，方便老板们参考：这款18万kW环能牌矿热炉煤气发电机组，整机占地面积约800㎡，适配30MVA及以上矿热炉的废气处理需求，机组运行时噪声控制在75-85dB（A），符合工业厂区噪声标准，相较于环能牌常规机组≤75dB（A）的噪声标准，更适配大型冶金厂区的生产场景；每年可回收利用废气约1.75亿立方米，减少废气排放1.75亿立方米，相当于每年少烧50万吨标准煤，环保效益突出，排放达国六标准，可轻松通过环保验收，也彰显了环能牌机组的环保实力。

　　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.

　　从成本角度来说，环能牌机组的优势更明显：以前矿热炉废气“点天灯”，每年不仅浪费能源，还需投入约50万元废气处理费；而使用这款环能牌发电机组，每年可发电10.6亿千瓦时，按工业用电0.5元/度计算，年发电收益达5.3亿元，扣除机组运维成本（每年约800万元），每年可净省成本超5亿元，投资回报率极高，一般3-4年就能收回设备投资，相较于普通机组，环能牌机组因运维间隔≥1000小时，后期运维成本可额外节省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.

　　而且环能牌机组操作简单，采用全自动PLC控制系统，1人可监管多台机组，实现“无人干预、少人值守”，每年可节省人工成本约60万元；机组使用寿命可达20年，远超环能牌常规机组10年以上的使用寿命，每年运维成本仅占总投资的1.5%左右，后期维护省心，不用投入大量人力物力，也体现了环能牌机组稳定、耐用的产品特质。

　　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.
