资料简介

美国能源部提议根据《2009年美国复苏与再投资法》(Recovery Act)向阿塞洛-米塔尔美国公司(ArcelorMittal USA, Inc.)的拟议项目提供财政援助。拟议中的项目将在安赛乐米塔尔位于印第安纳州芝加哥东部的印第安纳港钢铁厂建造和运营一个高炉煤气回收锅炉和配套基础设施。工厂占地约3400英亩。能源部提议的行动是向阿塞洛-米塔尔提供3150万美元的费用分摊安排。拟议项目的场址准备、设备安装和开办的总费用约为6 320万美元。目前，阿塞洛-米塔尔公司从印第安纳港生产的高炉煤气中，大约有22%是通过燃烧，然后通过一个排气口排放到大气中，这个过程被称为燃除。该公司使用剩下的78%的天然气为锅炉提供动力。这个拟议的项目将减少燃烧的废气量。这个提议的项目将利用废气来驱动一个新的80%效率的锅炉，每小时产生35万磅的蒸汽，然后用蒸汽来驱动现有的涡轮机发电。该锅炉将产生约38兆瓦的电力(每年333,000兆瓦时)，足以为30,000个家庭提供电力。

The U.S. Department of Energy (DOE or the Department) proposes to award a financial assistance grant under the American Recovery and Reinvestment Act of 2009 (Recovery Act) to ArcelorMittal USA, Inc. (ArcelorMittal) for its proposed project. The proposed project would construct and operate a blast furnace gas recovery boiler and supporting infrastructure at ArcelorMittal’s Indiana Harbor Steel Mill in East Chicago, Indiana. The mill occupies about 3,400 acres. DOE’s Proposed Action is to provide ArcelorMittal with a $31.5 million grant in a costsharing arrangement. The total cost of site preparation, equipment installation, and start-up of the proposed project would be about $63.2 million. At present, ArcelorMittal burns about 22 percent of the blast furnace gas from Indiana Harbor operations before releasing it to the atmosphere through an exhaust stack, a process called flaring. The company uses the remaining 78 percent of the gas to power boilers. The proposed project would result in a reduction of the amount of waste gas that is flared. The proposed project would use the waste gas to power a new 80-percent efficient boiler to produce 350,000 pounds of steam per hour, and then use the steam to drive existing turbines to generate electricity. The boiler would generate about 38 megawatts of electricity (333,000 megawatt-hours per year), enough to power 30,000 homes.
