iron and steel enterprises is a high energy-consuming enterprises, the existing two three steel oven, four blast furnaces, five converter, three rolling lines, the normal day production needs of nearly 5,000 tons of coal, coke need to outsource part of the supplement. Coke oven, blast furnace, converter distributed out of incomplete combustion of gas, have been released into the atmosphere around, polluting the environment. But now it is “fortune” as the three steel new economic growth point.

three steel concepts, consider that the business of “three wastes” waste gas, waste water, waste residues, only misplaced resources are treasures waiting to be tapped. The development of treasures, first from the coke oven emissions change “fortune” Start.

three steel lower heating value will be the introduction of coke oven blast furnace gas, coke oven coke as a fuel, replacement of a high calorific value of coke oven gas. The success of this technology, so that the same one 65-hole coke oven gas produced, not only to meet the demand for civilian workers, but also to meet the annual output of 2 million tons of steel three steel needs of all of the steel rolling plant furnace and a variety of furnace, kiln using the term gas, all of the chimneys are no longer black smoke, just rolling the system would save more than 30,000 tons per year of heating coal.

2004 Nian 3 Steel added 1 million tons of steel project put into operation, increasing a coke oven, a large 1000 cubic meters of blast furnace, a major converter of 100 tons last year’s steel production of 300 million tons, production increases, gas volume will be greatly divergent增加. 3 Steel seize the opportunity to invest 90 million yuan to build a new coal chemical recovery system, shortage of coking gas to purify recycled 2 a day coke-oven gas transported 950,000 cubic meters. Through the deep processing of coal-chemical system, the annual recycled 42,000 tons of tar, ammonium sulfate, 10,000 tons, benzene more than 6000 tons, and annual output value of more than 6500 million yuan, profit 30 million yuan, becoming three steel new profit growth point.

for the increase in emissions, three steel under different heat value of gas recovery and utilization of all-round form the whole plant gas pipe network. Add a coke oven, one-year increase more than 100 million cubic meters of gas heating value, so also ripe for the use of gas power generation. 3 Steel completed and put into a net condensation of two 15MW turbine-generator unit, the excess power to reach more than 60 million kilowatt hours. Last year, the use of blast furnace of the TRT TRT commissioning, Japan and generating increased more than 10 million kilowatt hours. At present, only nine sets three steel gas boiler, five blast furnace fan, five steel rolling production lines, all the six lime kiln gasification, Japan and generating capacity to reach more than 70 million kilowatt hours, equivalent to three 3 million tons annual production of steel steel outer purchase electricity with an annual output of 2 million metric tons in 2003 outsourcing power equivalent to rely on gas recovery to save up 1 million tons of steel’s electricity consumption.

循环经济：排气改变“财富”

钢铁企业是一个高耗能企业，现有的两个三钢焦炉，高炉四，五转换器，三轧线，正常日产近5000吨煤的需求，焦炭需要的部分外包补充。焦炉，高炉，分发了不xx燃烧的气体进行转换器，已被释放到大气层周围，污染环境。但现在是“财富如三钢”的新的经济增长点。

三钢的概念，认为对“三废”废气，废水，废渣，企业只有放错地方的资源财富可挖。宝藏的发展，首先从焦炉排放量的变化“财富”开始。

三钢的热值较低的将是引进的焦炭焦炉高炉煤气，焦炭作为燃料炉焦炭，高发热量的焦炭焦炉煤气替代。这项技术的成功，使同样的一个65洞的焦炉煤气生产，不仅要满足民工的需求，而且也满足了200.0万钢三钢钢的所有需要，年产轧钢厂加热炉炉和各种窑炉使用术语气体，所有的烟囱不再冒黑烟，只是滚动系统将节省超过每年30,000吨的取暖煤。

2004念3钢增加了1万钢铁项目投产吨，增长1焦炉，大型1000高炉，100吨去年的300万吨，产量增加，气体体积钢铁生产的主要换算立方米将大大不同增加。 3钢抓住机遇，投入900万元，建设一个新的煤化工回收系统，焦化煤气净化回收短缺每天2焦炉煤气输送九十五点零零万立方米。通过煤炭深加工，化工系统，年回收焦油4.2万吨，硫酸铵，1万吨，苯超过6000吨，超过65.0亿元，利润3000.00万元，年产值，成为三钢新利润增长点。

的排放量增加，三钢根据气体回收和全面形成全厂煤气管网的利用率不同的热值。新增焦炉，一年升幅超过1.00亿的天然气热值立方米，因此，也为天然气发电的使用时机已经成熟。 3钢建成并投入了2台15MW发电机组的净缩合汽轮发电机组，日发电量达到6000多万千瓦时。去年，爆破的泰爱泰党泰爱泰党熔炉使用调试，日本和生成增加超过10万千瓦时。目前，只有9套三钢煤气锅炉，高炉风机5，5轧钢生产线，所有6个石灰窑气化，日本和发电能力将达到70多万千瓦时，相当于3个3万吨生产钢钢外购买电力的200万吨，2003年年产外包权力相等于在煤气回收来挽救了1万钢的电力消耗吨。06.1.28
