to depend on coal quality. PCI rates of 200 kg/t HM are just like that practicable, earning you a little fortune of 180 kg coke/tHM plus the carbon footprint involved. What is more, stateoftheart technology by Küttner enables you to markedly increase PCI rates and benefit from lower raw material costs and higher productivity.

Most coal mills are designed around achieving 100% throughput at 50 to 52 HGI and grinding low HGI coals can lead to problems with regard to their capacity to deliver suitable PF to maintain full boiler output. In Queensland, one power station has successfully undertaken trials of low HGI coal (HGI = 29). The mills installed were Babcock and ...

Pulverized coal injection was developed in the 19th century, but was not implemented industrially until the 1970s. Rises in the cost of coke due to increased global demand and thus more competition for the resource have made this method attractive to the ironproducing industries and increased its value. The PCI method is based on the simple ...

2006, the main area for increased PCI consumption is still thought to be in Asia, particularly China and India (Boyle, 2006). The construction of new BFs and Asian steel producers utilising PCI coal at higher consumption rates will drive the demand for PCI coal. New BFs will be preferred over scrapbased minimills wherever steel demand is large,
