coke,charcoal etc. Answer: Primary Fuels are the natural Fuel. … Fuel which we get from natural resources are primary fuels while artificial fuels are Secondary fuels .
Is Coke a secondary fuel?
One of the important secondary fuels is coke. Coke is an important raw material in the blast furnace iron-making. It is a source of chemical and thermal energy in the blast furnace.
Is Coke used as fuel?
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. Coke from coal is grey, hard, and porous and has a heating value of 24.8 million Btu per ton.
Why Coke is not used as a fuel?
The term means a product similar to coal and mined the same way. Coal is cheaper and that is why it is used more often. … Coke is cleaner and other methods should be looked into before coal and oil run out.
What is difference between coke and coal?
What is the difference between coal and coke fuel? Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner.
What is secondary fuel?
Secondary fuels are fuels that are derived from some primary fuel or fuels through chemical or physical processes. These are fuels that are not found as a natural resource. … This means that secondary fuels are often an intermediate form of energy between the primary energy and the energy services.
What is the purest form of coke?
The purest form of Cocaine is a white, pearly product. The powder form of cocaine is a salt, which is typically cocaine hydrochloride.

What is hard coke?
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. … The carbon monoxide produced by its combustion reduces iron oxide (hematite) in the production of the iron product.
Is Coke a fossil fuel?
Coal gas, coke and producer gas are the byproducts of coal and are not fossil fuels, except natural gas which is a fossil fuel.
How is coke obtained from coal?
Metallurgical coke is produced by destructive distillation of coal in coke ovens. Prepared coal is “coked”, or heated in an oxygen-free atmosphere until all volatile components in the coal evaporate. The material remaining is called coke.
Can steel be made without Coke?
Now, nearly all new steel globally is produced using iron oxide and coking coal. … While an increasing amount of steel is being recycled, there is currently no technology to make steel at scale without using coal.
How did old coke ovens work?
In a process known as “coking,” coal was shoveled into beehive-shaped coke ovens insulated with a layer of dirt and then ignited. After laborers sealed the doors with brick and mud, the coal was left burning under low-oxygen conditions for two or three days and could reach temperatures of nearly 2000C (or 3600F).
What is green petroleum coke?
Green petroleum coke is obtained from processing liquid fractions in Delayed Coking Units (UCR). It is a material with high fixed carbon content comprising hydrocarbons and low levels of inorganic compounds.
How does a coke oven battery work?
A coke battery is made up of multiple ovens. Coal is crushed and blended prior to being charged in a coke oven. A larry car charges the individual oven with the blended coal. In the coke oven, the coal is heated to 1,800°F for up to 18 hours.
