XXXX Steel Limited is one of the largest steel companies in India. The wasted heat from the gas exhausted from No.2 (1670m³), No.3 (4019m³) and No.4 (4019m³) blast furnace hot blast stoves of this company are planned to be recovered according to the production requirements and energy saving and emission reduction requirements. The recovered heat will be used to heat the combustion air and gas. This can effectively reduce the temperature of exhaust gas, and improve the thermal efficiency of hot blast stove. By burning the preheated air introduced into the hot blast stove, the temperature in the hearth of hot blast stove can be improved, and the purpose of energy efficiency and temperature reducing can be achieved. 

Tianjin XXXX Co., Ltd. is a high-tech enterprise in Tianjin developed on the basis of technology. It is located in Ji County of Tianjin within the delta economic circle center of Beijing, Tianjin and Tangshan.

This enterprise was established in 1987. Its registered capital is 21.38 million Yuan. It has two production plants and one office area. Its floor area is 65,000m² and its building area is 31,000m². It has more than 600 employees, including 22 senior engineers and 52 engineers. This company sticks to the principle of scientific and technological innovation, promoting the transformation of achievements, finding out scientific measures of “Self-analysis to find the market, developing with targeted market, and concentrating efforts on promotion” to promote the enterprise development. Its main products are energy saving and environmental protection products. At the early of 1990, our enterprise introduced aerospace hi-tech – “Hot tube” from the Institute of Physics Chinese Academy of Sciences. Leading by this, our enterprise has developed and researched dozens of new energy saving equipments. In 1998, we introduced U.S. technology – production line of nickel-based brazing fin tube, and developed alloy brazing hot tube.

Science and technology brings the flourish of the enterprise. The output of energy saving products has doubled in successive years, and we rank among the first in domestic counterparts. Meanwhile we are awarded with a number of honors, including 3 achievements with the title of National New Products, 4 achievements with first, second and third prize of scientific and technological progress in Tianjin, and 6 national patents. In 2003, Tianjin Science and Technology Commission named our enterprise as the "high-tech enterprises"; in 2001, our company has achieved ISO9001: 2000 Quality System Certification; In April 2001, our company obtained the design and manufacturing license of pressure vessel.

On the basis of introducing in technologies, Tianjin XXXX Co., Ltd. has been paying attention to the development of new products. It has been updating and retrofitting its original products to improve their content of science and technology. Its products are sold throughout 28 provinces, municipalities and autonomous regions and exported to Indonesia, Singapore, Sudan, Mongolia and Vietnam.

XXXX钢铁有限公司是印度最大的钢铁公司之一，根据其生产和节能减排的需要，拟将公司的2#（1670m³）、3#和（4019m³）4#（4019m³）高炉热风炉的废热烟气进行余热回收，加热助燃空气和煤气，一方面可有效降低排烟温度，提高热风炉热效率；另一面预热后的空气进入热风炉炉内燃烧，可提高热风炉炉膛温度，达到节能降温的目的。

天津XXXX有限公司是一个靠科技发展起来的天津市高新技术企业。位于天津市蓟县，座落在京、津、唐三角经济圈中心。

公司于1987年建厂，注册资金2138万元。现有两个生产厂区和一个办公区，占地面积65000m²、建筑面积31000m²、注册资本2138万元。现有职工600余人，有高级工程师22人，工程师52人。公司坚持科技创新，促进成果转化，走出一条“分析自我找市场，瞄准市场搞开发，集中精力搞推广”的科技兴厂之路，生产的产品以节能、环保型为主。1990年初，我公司由中科院物理研究所引进宇航高新技术——“热管”，并以此为龙头，不断推陈出新，开发、研制出数十项新型节能设备。1998年又引进美国技术——镍基钎焊翅片管生产线，开发出合金钎焊热管。

科技换来企业兴，节能系列产品产值连年翻番，位于国内同行之首。同时也获得了诸多荣誉，其中三项成果获得国家级新产品称号，四项成果获天津市科技进步一、二、三等奖，取得了六项国家专利。2003年天津市科委命名为“高新技术企业”；2001年通过“ISO9001国际体系认证”； 2001年4月，取得压力容器设计、制造许可证。

天津XXXX有限公司在引进技术的基础上，重视新产品开发，对原有产品不断更新改进，提高其科技含量，产品畅销全国二十八个省、市、自治区，并出口到印度尼西亚、新加坡、苏丹、蒙古、越南等。
