1 Mixed gas has gained a lot of popularity over the past decade or so. It’s usually a mixture of coke oven gas and liquefied petroleum gas. Mixed gas tends to be more energy efficient and thereby cost efficient in the long run. MIXED GAS

2 There are many types of coal that are used as fuel in rotary kilns for calcination. The main types are: bituminous coal lignite and slime. There are also various factors that are considered while burning coal as fuel. These can be regulated to make sure that coal is less polluting . COAL

3 COKE OVEN GAS Nowadays a majority of furnace fuels such as blast furnace gas release furnace gas ferroalloy furnace gas and so on are made up predominantly of coke oven gas. While compared to other fuels coke oven gas is clean cheaper and much easier to transport and store. That’s why it has become one of the most used fuels in recent times.

4 OIL Oil or just petroleum was once a preferred way of burning the furnaces at calcination kilns. Now however the demand has died down mostly because it’s expensive and very polluting. Some plants prefer to use a combination of coal and petroleum. It’s called Pulverised Petroleum and is used only in very specific types of rotary kilns.
