中国是世界第一大铁合金生产大国，铁合金产品较为齐全，其中的矿热炉产品主要有：电石、工业硅、硅铁合金、硅锰合金、铬铁、镍铁、钛渣等。在这之间产量最高的又有硅锰铁（1000万吨）、高碳铬铁（580万吨）、硅铁（580万吨）等。各类铁合金企业也依托于每年总体3000万吨以上的产量应运而生，众所周知，此一类型企业属于高能耗企业，因此在近些年国家提出“双碳”目标之后，严控单位能耗、淘汰落后产能、减少工业尾气排放、妥善利用工业尾气发电机组创造效益成为了最为主要的发展方向。

　　China is the world's largest producer of ferroalloys, with a relatively complete range of ferroalloy products. Among them, the main products of the submerged arc furnace include: calcium carbide, industrial silicon, ferrosilicon alloy, silicon manganese alloy, chromium iron, nickel iron, titanium slag, etc. Among them, the highest production includes silicon manganese iron (10 million tons), high carbon chromium iron (5.8 million tons), and silicon iron (5.8 million tons). Various types of ferroalloy enterprises have also emerged based on an annual output of over 30 million tons. As is well known, this type of enterprise belongs to high-energy consumption enterprises. Therefore, after the country proposed the "dual carbon" target in recent years, strict control of unit energy consumption, elimination of outdated production capacity, reduction of industrial exhaust emissions, and proper utilization of industrial exhaust power generation units to create benefits have become the most important development direction.

　　可又该如何去做、去实现呢？我们都清楚，在工业生产中由于产品和工艺特点，会产生各种可燃气体，其中矿热炉尾气就属于比较典型的工业尾气，同样它也是大量的可燃尾气，只要通过工业尾气发电机组利用好这些尾气，就能够实现变废为宝的奇迹，也可以帮助企业在创造效益的同时节能减排。

　　But how should we do it and achieve it? We all know that various combustible gases are generated in industrial production due to the characteristics of products and processes, among which the tail gas of mineral thermal furnaces is a typical industrial tail gas. It is also a large amount of combustible tail gas. As long as these tail gases are well utilized by industrial tail gas generators, the miracle of turning waste into treasure can be achieved, and it can also help enterprises save energy and reduce emissions while creating benefits.

　　既然想要去更好的利用工业尾气为我们自身服务乃至于创造应有价值，那么首先就需要弄清楚它的产生、结构、“产量”等源头问题，其主要由CO和H?构成，是在生产过程中伴随产出的，按照漏风率8%估算，基本上可以达到一吨硅锰合金产气量960~1100Nm?左右，影响此类工业尾气质量的因素是电炉的密封状况，产量如此巨大的矿热炉工业尾气，一旦合理利用，将会通过工业尾气发电机组创造出比较可观的效益。而其利用方法主要有蒸汽锅炉发电、内燃机发电、制甲醇、乙醇，烧石灰窑等。

　　Since we want to better utilize industrial exhaust gas to serve ourselves and create value, we first need to understand its generation, structure, "output" and other source issues. It is mainly composed of CO and H?, which are produced during the production process. According to an estimated air leakage rate of 8%, the gas production of one ton of silicon manganese alloy can basically reach about 960-1100 Nm?. The factor affecting the quality of such industrial exhaust gas is the sealing condition of the electric furnace. With such a huge output of mineral thermal furnace industrial exhaust gas, once properly utilized, it will create considerable benefits through industrial exhaust gas generator sets. And its utilization methods mainly include steam boiler power generation, internal combustion engine power generation, methanol and ethanol production, lime kiln firing, etc.

　　近年来，随着在内燃机发电技术的引领和市场的推动下，矿热炉工业尾气发电机组得到了大量的推广应用以及用户的高度认可，也为苦苦寻找更优工业尾气解决方案的客户雪中送炭，尤其是在能耗双控政策大背景下，降低了企业能耗、为企业创造了可观的收益，实现了节能减排，提高了铁合金企业的盈利能力。

　　In recent years, with the leadership of internal combustion engine power generation technology and the promotion of the market, the industrial exhaust gas generator set of the ore blast furnace has been widely promoted and highly recognized by users. It has also provided timely assistance to customers who are struggling to find better industrial exhaust gas solutions, especially in the context of the energy consumption dual control policy, which has reduced enterprise energy consumption, created considerable profits for enterprises, achieved energy conservation and emission reduction, and improved the profitability of ferroalloy enterprises.

　　环能工业尾气发电机组，具有灵活、适应性强、建站周期短等特点，主要采用12V190机型，该机型成熟、可靠、市场占有率高。应用了多项科美自主核心技术，包括双路进气双增压、单缸控制、缸内混合、自动控制等技术，彻底解决了传统预混进气结构内燃机由于氢气导致的回火，可靠性差，运行成本高等问题，成功实现了工业尾气内燃机发电的市场化运行。

　　The environmental energy industrial exhaust gas generator set has the characteristics of flexibility, strong adaptability, and short construction period. It mainly adopts the 12V190 model, which is mature, reliable, and has a high market share. Multiple independent core technologies from Kemei have been applied, including dual intake and dual boost, single cylinder control, in cylinder mixing, automatic control, etc., completely solving the problems of backfire, poor reliability, and high operating costs caused by hydrogen gas in traditional premixed intake structure internal combustion engines. The market-oriented operation of industrial exhaust internal combustion engine power generation has been successfully achieved.

　　如生产中耗电量大概在4000kW?h/t的硅锰合金，在这一过程里可产生尾气1100Nm3/t，除去厂内矿石烧结、预热等用气外，可用于发电的尾气在600~700Nm3/t这一区间内，若采用科美工业尾气发电机组进行能源的二次利用，按照一方气发一度电计算，可发电600~700kW?h，相当于帮助企业每年减少15~20%的能耗！

　　If the production of silicon manganese alloy consumes approximately 4000 kW · h/t of electricity, it can generate 1100 Nm3/t of tail gas during this process. In addition to the gas used for ore sintering and preheating in the factory, the tail gas that can be used for power generation is in the range of 600~700 Nm3/t. If the Kemei Industrial tail gas generator set is used for secondary energy utilization, according to the calculation of one cubic meter of gas generating one kilowatt hour of electricity, it can generate 600~700 kW · h of electricity, which is equivalent to helping the enterprise reduce energy consumption by 15~20% annually!

　　由此可见，巧妙使用工业尾气进行发电，不仅能够满足日渐提高的环保要求，还具有广阔的市场前景，而一直深耕于此的科美人，将一如既往的通过技术引领市场，转化废气变现为效益，为企业提供更优质的工业尾气发电机组，助力铁合金企业的发展，致力行业的节能减排，为铁合金行业的稳定、有序、向好，矿热炉尾气的利用做出应有的贡献。

　　From this, it can be seen that cleverly using industrial exhaust gas for power generation not only meets the increasingly high environmental requirements, but also has broad market prospects. Kemei, who has been deeply rooted in this, will continue to lead the market through technology, convert exhaust gas into benefits, provide higher quality industrial exhaust gas generator sets for enterprises, help the development of ferroalloy enterprises, and strive for energy conservation and emission reduction in the industry, making due contributions to the stability, orderliness, and improvement of the ferroalloy industry, as well as the utilization of blast furnace exhaust gas.
