采用捣固炼焦技术制备冶金焦

由于新的炼焦工艺一捣固炼焦的广泛使用，使得我国的煤炭资源更能够被充分利用，尤其是大同地区优质、低灰、低硫、高挥发分、弱黏结性或不黏结性的煤，用大同地区的煤作配煤炼焦，不仅提高了该地区煤的使用价值，在一定程度上降低钢铁生产成本，而且缓减了我国煤炭资源肾张的压力。本文采用捣固炼焦技术，配合一定比例的大同弱黏结性煤进行炼焦试验，取得成功，并拟建一座年产100万t的冶金焦的焦化厂。介绍了焦炉在生产过程中烟气排放污染的前期控制概况及高压氨水泵应用变频器改造中存在的问题和解决方案，以及改造后无烟装煤效果和节能效果。

The Stamp Charged Coking Technique for the Production of Metallurgical Coke

A widely use of new coking technique, stamp charged coking which can use some proportion the coal of high quality, low ash and sulfur, high volatile and light sticky or no-sticky in Da Tong area not only raises the value of local coal but also decreases the cost of the steel production and alleviate the stress of shortage of coal resource. The paper is a successful a coking test by use some light sticky coal in Da Tong area. The test result will be put into use in a coking plant with production of 1 million per year.
