FINEX的优势是用贮量丰富的普通煤种代替焦煤,但流态化反应器的还原效率不如竖炉,其金属化率只有80%~85%,增加了熔融气化炉的还原负担,使得每吨生铁耗用的煤量要比高炉高得多。目前,先进的大型高炉燃料比约500kg/t,而FINEX约850kg/t(也有报导是1050kg/t),还有500Nm3/t的氧气消耗。如高炉工艺考虑焦化、烧结、球团等铁前工序的全流程
FINEX has the advantage of replacing the coking coal with ordinary coal, which is rich in reserves. However, the reduction efficiency of the fluidized reactor is not as good as that of the shaft furnace, and its metallization rate is only 80% -85%, increasing the reduction burden of the melting gasifier, The amount of coal consumed per ton of pig iron is much higher than the blast furnace. Currently, the advanced large-scale blast furnace fuel ratio is about 500 kg / t, while FINEX is about 850 kg / t (also reported as 1050 kg / t), with an oxygen consumption of 500 Nm3 / t. Such as blast furnace process consider coking, sintering, pellets and other iron processes before the entire process
