1988年,我国炼焦用洗精煤产量达7234万吨。全国焦炭产量为6108万吨,其中机焦4631万吨,土焦为1477万吨,土焦占全国焦炭总产量的24.2％,比例十分可观。国务院于1982年发布第五号节能指令,1986年颁发了《节约能源管理暂行条例》,1989年发布的《国务院关于产业政策要点的决定》,在这些文体中都明确提出严格限制土焦生产。但至今土焦产量仍不断增长。为了弄清这一问题,本文对土焦生产状况、存在问题、应采取对策进行阐述。一、土焦生产状况有炼焦煤资源的地方,就有土焦生产。土焦产量逐年增长见表1:
In 1988, China’s coking coal washing output reached 72.34 million tons. The national coke output is 61.08 million tons, of which 46.31 million tons are machine coke, 14.77 million tons are earth coke, and soil coke accounts for 24.2% of the total coke output in the country. The proportion is very impressive. The State Council issued the Fifth Energy-Saving Directive in 1982, the Provisional Regulations on Energy Conservation in 1986 and the Decision of the State Council on the Essentials of Industrial Policies issued in 1989, all of which expressly set forth strict restrictions on the production of soil coke. But so far the production of earth coke is still growing. In order to clarify this issue, this paper on the state of coke production, there are problems, should take countermeasures to elaborate. First, the state of coke production of coking coal resources, there is coke production. Coke production increased year by year in Table 1:
