COAL PULVERIZING SYSTEM . Figure 1 shows a typical mill system schematic including fuel bunker, feeder, mill, primary air system and relevant dampers. Raw coal is fed from the feeder at a controlled feed rate, to meet boiler steam demand. In the meantime, hot primary air of 300°F to 700°F, depending on coal moisture content, is
Each mill system consists of a separate exhauster, control damper, cold and hot temper ing air dampers, gravimetric coal feeder, Combustion Engineering mill, riffle dis tributors, and DB Riley SLS 140 internal dynamic classifier. (See Figures 1 and 2). The aircoal mixture passes upward into the dynamic classifier with its ...
A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

Dry coal that is allowed to remain in the pulverizer system can spontaneously ignite. Raw coal to the pulverizer must be uninterrupted and controllable. Precise feeder control and minimal stoppages above and below the feeder are crucial. Hot smoldering or burner raw fuel anywhere in the pulverizer system is considered serious.
Aug 18, 2020· The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction. Principle of Coal Feeder: Coal that has been crushed with a Crusher will be transported by belt conveyor to Coal Yard for stock and Coal Bunkers.
2. High mill coal spillage 3. Low pulverized fuel fineness 4. Mill fire 5. Low capacity of mill . Raw Coal Feeders . The purpose of a RC feeder in the coal pulverizing circuit is to feed the raw coal from the bunker into the pulverizer in controlled and varied quantities corresponding to the boiler load demand.
Jul 31, 2011· Pulverizers prepare raw fuel by grinding it to a desired fineness and mixing it with the just the right amount of air before sending the mixture to boiler burners for combustion. In Part I of ...
The system should be designed to resist the passage of air and gas from the pulverizer through the coal feeder into the coal bunker. To withstand pulverizeroperating pressures and to resist percolation of hot air/gas, a vertical or cylindrical column of fuel at least the size of three coalpipe diameters should be provided between the coal ...
Feb 08, 2018· Pulverized coal is the most widely used fuel in the steel sector. Watch how its selection, pulverization and quality check using a bomb calorimeter is key to an energy efficient system.
