oxygen enriched blast

The high temperature melting furnaces with coke bed, oxygen enriched blast and two row tuyeres for smelting reduction were developed in west countries. With these furnaces the solid municipal waste could be treated for recycling, re using and innocuous disposal.

先进国家利用熔融还原技术开发了高温焚烧炉，这种带有焦炭床、富氧和双排风口的高温炉，可以达到对固体废弃物进行无害化和资源化的处理。

The oxy-coal technique of blast furnace means the blast furnace operates with ultra-high PCI and more than 40% oxygen enriched blast.

高炉氧煤炼铁是指高炉鼓风富氧超过40%以上的超量喷煤技术。

Practice of injection of pulverized coal with oxygen enriched blast on No2 BF at Shijiazhuang Iron& Steel Works

石钢2号高炉富氧喷煤实践

It shows that ① with a metallization degree of burden more than 40 per cent, blast furnace can ′ t be operated with oxygen enriched blast.

结果表明：1炉料金属化率达到40%后，高炉不能富氧操作；
