近几年我国土焦的产量超过1,000万吨,约占全国焦炭总产量的25～30％。土焦生产对解决我国钢铁、化肥等工业发展中能源不足问题起了积极的作用,这是必须肯定的。然而土焦生产与机焦生产相比,劳动生产率低,环境污染严重,重要的是浪费能源。不仅煤耗大,而且宝贵的化学产品不能回收。据实际调查和设计资料计算,用洗精煤炼土焦,每吨土焦比机焦多消耗和少回收的能源(折标准燃料)530公斤左右。使用原煤炼土焦所浪费的能源就更多了。若按1978年全国产土焦1,300万吨计算,全年浪费能源近700万吨。此外,由于土焦质量
In recent years, China’s coke production more than 10 million tons, accounting for about 25 to 30% of the country’s total coke production. Coke production to solve China’s iron and steel, fertilizer and other industrial problems in energy development played a positive role, which is to be affirmed. However, compared with machine coke production, the coke production has low labor productivity and serious environmental pollution. It is important to waste energy. Not only large coal consumption, but also valuable chemical products can not be recycled. According to the actual investigation and design data calculation, with coal washing coke, coke per ton of coke more than the consumption of light and less recycled energy (fuel) standard about 530 kg. The use of raw coal coke waste of energy is even more. If calculated according to the country’s 13 million tons of coke produced in 1978, nearly 7 million tons of energy were wasted throughout the year. In addition, due to the quality of soil coke
