Carbonization of Non-Coking Coal

Behera, Kishore Kumar and Behera, Sushil Kumar (2015) Carbonization of Non-Coking Coal. BTech thesis.



Since coking coal reserves all over the world is not sufficient to meet the demand of fuel used in iron making,DRI route of iron making is being adopted.Taking into account the current scenrio ,India produces around 20 MT per annum in which non-coking coal is used extensively.In this project work,studies on effect of different carbonisation temperatures(400,600,800,1000),chemical and physical properties(Proximate analysis,caking characteristics,porosity) of different coal samples,obtained from different mines in India were conducted for their effective use in sponge iron making.In the project work studies has been done on chars prepared from Jagannath,Lingaraj Mines,Ananta mines,Bhubaneswari and Talcher open field mines. Non-coking coals at four different Carbonisation temperatures were analysed for detremination of their physical and chemical properties.It was concluded that increase in carbonisation temperature,volatile matter and calorific value decreases where as fixed carbon content and ash content increases.It was also found out that Bhubaneswari mines coal has high fixed carbon content. Talcher mines coal has highest calorific value.This test examines which coal is best applicable for industrial applications like sponge iron making.Studies on different soaking rate as well as different soaking time was also investigated.
