世界煤焦生产消费及贸易状况

在未来10年内,高质量的炼焦煤仍不能满足供应,供需紧张状况仍将继续下去。要采取步骤减少对炼焦煤和焦炭的依赖。高炉喷吹煤粉技术将有所发展;预计到2000年,焦比将降到330kg/thm。到2000年,煤炭需求增长率为1.4%(即4132Mt),产量可达4160Mt。北美、拉美和亚洲国家煤炭产量将有所增长。澳大利亚和美国将继续成为主要煤炭出口国。

THE SITUATION OF WORLD COAL AND COKE PRODUCTION,CONSUMPTION AND COAL TRADE

In the coming 10 years,the high quality coking coal will continue to curtail coal usage unless absolutely necessary.This will promote research into steel making without or with reduced amounts of co- als.Further technical advances of the pulverized coal injection in the bla- st furnace will be progressed in the future.The coke rates obtained by using PCI have been as low as 330 kg/thm in regular operation in 2000.In annual terms the growth of coal demand equates to 1.4% p.a.(4132 Mt). Coal production globally will be adequate to meet all normal demand con- ditions.It is therefore expected to increase to 4160 Mt in 2000.These countries in North and Latin America and Asia,hard coal production wi- ll increase throughout the period.Australia and United States of America are expected to expand rapidly for the coal export market.
