A pulverized coal-fired 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
An overwhelming majority of coal fired boilers utilize a pulverized coal firing system These systems utilize a pulverizer or mill to grind coal to a desired fineness and subsequently transport the coal to the burners using air as a transport medium Air utilized to transport coal to the burners ,

Fire and Explosion Prevention in Coal Pulverizing Systems
today, there normally exists a combustible coal/ air mixture in the burner lines and pulverizer equipment Hence there is the continual danger of fires and, under certain conditions, explosions Proper design and operation of the pulverized coal burners protects the pulverizing system from ignition from the furnace fire
The coal in the hopper is conveyed to the coal pulverizer by screw conveyor The coal pulverizer will crush the coal into pulverized coal In the coal burner, the pulverized coal mixes with air (High-speed air flow is generated by the draft fan on the coal burner), and is ignited by the oil burning igniter Ignition
B&W engineers designed the AireJet burner with an innovative burner structure — a burner built around a center jet of air, encircled by the fuel stream, and then wrapped in additional combustion air Pulverized coal-fired boiler applications; Much cleaner burning so it requires less excess air to minimize carbon monoxide (CO) and unburned carbon
Transportation of pulverized coal from the pulverizer to the burner • Provides the necessary heat requirement to facilitate evaporation of surface and inherent moisture in the coal • After coal and air is mixed at the pulverizerthe resulting mixture of air/coal is typically called dirty airflow • The use of air to transport coal to .
Coal-Fired Power Plant Burner Isolation Valve - TSA SALES
From the coal bin, the coal is fed into the coal pulverizer and dried using ~300° F air When coal is pulverized, the process grinds the coal into a fine dust which expands the coal’s surface area allowing the coal to ignite quicker and burn hotter and faster
linear flow of the pulverized coal and restraining the pulverized coal from mixing with the secondary air and scattering into the external circulating flow Just like the DF burner, the A-DF burner generates internal circulating flows by using air register vanes, realizing low-slagging firing while maintaining ignition stability and low NO x

Coal Drying Improves Performance and Reduces Emissions
coal is pulverized and dried Dryer coal is easier to pulverize, and less mill power is needed to achieve the same coal fineness Additionally, with less fuel moisture, more complete drying of coal can be achieved in the mill This results in increased mill exit temperature (the temperature of the coal and primary air mixture at mill exit .
The coal is slow-burning and difficult to ignite because of its high density, so few pulverized, coal-fired plants burn it Heating Value Anthracite burns the hottest among coal types (roughly 900 degrees or higher) and typically produces approximately 13,000 to 15,000 Btu per pound Waste coal discarded during anthracite mining, called culm .
