Abstract. Coal can be burned in a number of ways. Depending on the characteristics of the coal and the particular boiler application, the designer may chose pulverized coal (PC) firing, cyclone firing, stoker, or fluidized bed firing methods. Whatever method is applied, raw coal should be prepared before being fed into the furnace.

Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".
