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.
As one of the world’s leading coal pulverizer manufacturers, Williams has the most advanced direct fired coal and pet coke pulverizing system in the field today. Design features of our coal pulverizer emphasize improved system reliability, constant product size control, and reduced energy requirements.
2. Central or Bin System: The crushed coal is fed to the drier from the raw coal bunker by gravity. The drying of coal is effected either by using hot gases, preheated air or bled steam. The dried coal is fed to the pulverizer with the help of feeder. The pulverized coal is carried from the pulverizer mill with the help of air and it is separated in the cyclone separator.
For purposes of the discussion that follows, the coal-fired power generation systems referred to above are considered to consist of essentially the following major operating components: a coal feeder, apparatus for pulverizing coal, a distribution system for distributing the coal after the pulverization thereof, a furnace in which the coal is
Section 100 is made up of the following key areas: Coal Handling; Coal Pulverizing and Drying; High-Pressure Solids Feeding (Petrocarb); Coal Gasification; Slag Handling; Char Separation, Char Cooling, and Recycle Gas System; Gas Cooling and Superheated Steam Production; and a Gasifier Start-Up System. The coal handling system unloads raw coal from rail cars and crushes and transports it to
