目前,我国年产原煤六亿多吨,大部分未经洗选加工就直接供应用户使用,矸石多,灰分高,品种、规格不对路,热效率低,造成很大浪费。为了节约能源,减少矸石运输,防止环境污染,并提高工业产品质量,必须积极发展煤炭洗选加工,合理使用煤炭,逐步由主要燃用原煤改为主要燃用加工商品煤。为此,特发布如下指令:一、逐步做到按用户需要供应加工商品煤。全国统配煤矿要从一九八三年开始,到一九九○年底止,根据煤炭洗选加工和运输等条件,分期分批实现如下要求:1.冶金焦炭用煤。一般要全部使用洗精煤,未经洗选的煤不得炼焦。洗精煤含硫要在1.5%以下,主焦煤、肥煤的洗精煤灰分要在12%以下,气煤的洗精煤灰分要在10%
At present, China has an annual output of more than 600 million tons of raw coal, most of which are directly supplied to customers for use without washing and processing. There are many gangue and ash with high ash content, varieties and specifications, and the heat efficiency is low, resulting in great waste. In order to save energy, reduce the transportation of waste rock, prevent environmental pollution and improve the quality of industrial products, coal washing and processing must be actively developed, coal should be rationally used, and the main burning coal should be gradually changed to the main burning coal for processing and processing. To this end, issued the following special instructions: First, and gradually do according to user needs supply of processed coal products. The coal mines nationwide should start from 1983 and by the end of 1990, meet the following requirements in batches and in batches according to the conditions of coal washing, processing and transportation: 1. Coal for metallurgical coke. Generally use all clean coal, coal can not be uncoiled coking. Clean coal sulfur content should be below 1.5%, the main coking coal, fat coal washing coal ash content should be below 12%, coal gas coal ash in 10%
