Your coal feed can't be depended on to have the same density, the same calorific value or even the same lump size. PFISTER® rotor weighfeeders are gravimetric, meaning that the coal is weighed as it is dosed, so variations in size and density don't have the same impact on dosing accuracy.
It is also known as steam coal as it is pulverized and fed to boilers to generate steam. Coking CoaL Coking coal refers to coal with GCV greater 5700 Kcal/Kg on an ash-free but moist basis, that allows production of a coke suitable to support a blast furnace charge .
Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.
coal to the pulverizer is not a simple task since the coal properties constantly vary due to sizing differences and the adverse impact of moisture on heating value, flow characteristics, and density. The effects of moisture on coal has been studied for many years with research conducted by many institutes, who have published data
