Pulverized Coal Processing Plant

Pulverized coal (PC) combustion is presently the system of choice for coal-fired power-generating plants. In PC combustion, the coal is dried and is ground to a specified fineness, with a maximum particle size of 250–300 μm, depending on the reactivity of the coal.

Pulverized coal power plants are broken down into four categories, with operating temperatures and pressures as a function of the steam temperature and pressure: • Subcritical pulverized coal (SubCPC) plants, below the critical point of water (540°C and 170–220 bar), have an operating efficiency <38%. •

Pulverized Coal Injection Pulverized Coal Injection (PCI) is a process that involves blowing large volumes of fine coal granules into the BF. This provides a supplemental carbon source to speed up the production of metallic iron, reducing the need for coke production. As a result energy use and emissions can be reduced.

In conventional coal-fired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C. This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a temperature of 540 o C.

Process Control Abstract: A pulverized coal processing system for produc-ing coal powder used in aluminum alloy smelting process was introduced. The explosibility of the coal used in the system was measured, and the hazards of the process were analyzed. Explosion prevention and protection methods ap-

Adjusted for the entire pulverized coal fired utility industry, there is almost one explosion event each day. Even though a small percentage are of the containment breaking type, the other events have the potential of being true explosions. In addition, there is a wide range of explosion frequencies from plant to plant.
