摘要:鋼鐵行業排放的廢物種類繁多，例如：高爐渣、鋼渣、含鐵塵泥等。據有關專家介紹，目前我國高爐渣的年產生量在1億噸以上，利用率一般在65%~85%左右，鋼渣的年產量在6500萬噸左右，平均利用率僅為26%。截止2006年，我國鋼渣已超過了1億噸的積存量。多種廢渣的堆積、丟棄不僅占用大量的土地資源，而且還嚴重污染環境，對人類造成居住環境的惡劣影響。為了提高廢渣的利用率和再利用價值，近年來國內外的生產企業十分注重廢渣再利用技術的研究，積極探索利用量大、附加值高的廢渣利用新途徑以促進經濟社會與環境協調發展。

　　　本課題通過對冶金固體廢棄物和燃煤固硫劑的種類、性質的介紹，表明將冶金固體廢棄物處理利用是有必要的。所以本文對煤燃燒過程中傳統的鈣基固硫劑性質及脫硫過程機理進行綜合分析，提出一種新型的含有冶金渣的燃煤固硫劑。研究結果表明，冶金渣是可以成為燃煤過程中經濟而有效的固硫劑。

ABSTRACT:Blast furnace slag, steel slag is waste iron and steel industry. According to experts, the current blast furnace slag in China annual yield at 1 tons, the utilization rate of steel slag is about 70%~85%, the annual production of about 57000000 tons, the average utilization rate was only 25%. As of 2006, the accumulated amount of our country has more than 1 tonnes of steel slag. Accumulation of two kinds of waste not only take up a lot of land resources, but also pollute the environment seriously. In order to improve the utilization of waste and recycling value, in recent years, domestic production enterprises paid great attention to waste recycling technology research, and actively explore the use of a large quantity, high added value of the residue with new ways to promote the coordinated development of economy, society and environment.

　　　In this paper, by type of metallurgical solid wastes and coal sulphur-fixing agent in nature, shows that the metallurgical solid waste treatment and utilization is necessary. Therefore this paper on the mechanism of calcium based traditional sulfur fixation agent properties and desulfurization process in coal combustion process analysis, puts forward a kind of new metallurgical slag containing sulfur agent. The results show that, the metallurgical slag can be economically and effectively during coal combustion sulfur fixing agent.
