　　余热锅炉作为今年会jnh十一大主题专长技术之一，在结构设计、强造循环、热力推算、节造系统、清灰设备等关键技术方面占有自主知识产权专利20 余项。可能有效解决积灰、结渣、侵蚀和磨损等难点问题，具备配套炉型多、利用领域广、靠得住性高、经济效益好蹬着点。

　　技术指标：最大蒸发量可达到164t/h；蒸汽压力最大6.0MPa；蒸汽温度最高420℃；可能实现强造循环、天然循环+ 强造循环。截至2015 年6 月，中国今年会jnh总承包有色冶炼余热锅炉49 台，设计并运行余热锅炉已达130 台，蕴含世界上首台蒸发量最大的富氧顶吹镍熔炼炉余热锅炉（规模为100 万t/a, 蒸发量160t/h）、首台蒸发量最大的铜闪快炉余热锅炉（规模40 万t/a, 蒸发量116t/h）、世界首台蒸发量最大的锌浸出渣熔炼炉余热锅炉（蒸发量164t/h，4.6MPa，260℃），创造了12 项国内有色冶金余热锅炉的总包首例，并刷新日本、美国、德国设计的余热锅炉8 项。先后为金川、白银、五矿、中金、大冶、江铜、云铜、云锡、吉镍、中色等公司提供优越产品，并将余热锅炉输出到印度、巴基斯坦、赞比亚、刚果（金）、刚果（布）、缅甸、越南、巴布亚新几内亚等10 余国度。　　有色余热锅炉项目曾获优良工程设计奖金质奖1 项，银质奖2 项，省部级优良工程设计一等奖4 项，省部级科技进取一等奖4 项。

Smelting Waste Heat Boiler（WHB）

Core technical equipment of China ENFI, with a number of patented technologies, by membrane wall, convection bank, steam drum, vibration device and other components, and is the key equipment of waste heat recovery of flue gas. Non-ferrous smelting waste heat boiler is to achieve safe production of heavy nonferrous metals smelting and energy saving key core equipment, complete flue gas cooling, dust, and waste heat recovery, create conditions for the subsequent dust collecting and sulfuric acid manufacture. Since 1960s,China ENFI as China representatives introduces WHB of reverberatory furnace,

fluidized bed furnace, roaster, flash furnace, QSL furnace and other furnace from, Japan, Finland, West German and other countries, and then self-developed WHB for smelting of lead, zinc, copper, nickel, tin and other non-ferrous metal. ENFI’s WHB ended China must reply on the WHB imported history, and can perfect match bottom blowing smelting furnace, ISA furnace, Ausmelt furnace, rotary kiln, boiling roaster, blast furnace, reverberatory furnace, electronic furnace, fuming furnace, sintering furnace, converter and other process smelting furnace. After unremitting efforts of several generations to explore, innovation and development, WHB of ENFI has reached domestic leading level, and entered the advanced international ranks.　　Technical indicators: maximum evaporation can reach 164t / h; maximum steam pressure is 6.0 MPa; highest steam temperature is 420 ℃ ; WHB can realize forced circulation, natural circulation + forced circulation.　　As of June 2015, China ENFI has completed 49 EPC projects of WHB, the design and operation of WHB has reached 130 sets, including the world's first evaporation largest WHB of top-blown oxygen-rich nickel-smelting furnace(capacity is 1,000,000t/a, evaporation is 160t/h), the world's first evaporation largest WHB of copper flash furnace (capacity is 400,000t/a, evaporation is 116t/h), the world's first evaporation largest WHB of zinc residue smelting furnace(evaporation is 164t/h, pressure is 4.6 Mpa and temperature is 260℃ ). China ENFI has created 12 first domestic EPC projects of WHB, and completes 8transformation WHB designs of Japan, USA and German. China ENFI supply excellent product to domestic company such as JNMC, BNMC, MINMETALS, China National Gold Group Corporation, DAYE NONFERROUS, Jiangxi Copper Corporation, CHINALCO, Yunnan Tin Company Limited, Jilin Jien Nickel Industry Co., Ltd, CNMC, etc. China ENFI also export WHB to about 10 countries including India, Pakistan, Zambia, The Democratic Republic of Congo, Republic of Congo, Myanmar, Vietnam, Papua New Guinea.

WHB project of ENFI is eligible for 1 gold award and 2 sliver awards of excellent engineering design, 4 first prizes of provincial and ministerial award of excellent engineering design, and 4 first prizes of provincial and ministerial award of scientific and technological progress.
