Pulverized Coal Fired Steam Boilers

21/09/2015Pulverized Coal Fired Steam Boilers 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 pulverized fuel is to use the whole volume of the furnace for the

Pulverized coal

In the coal burner, the pulverized coal mixes with air (High-speed airflow is generated by the draft fan on the coal burner), and is ignited by the oil-burning igniter. After it passes through the turbine (one to three-stage), the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.

Coal normally is available to power plants in large lumps ranging from 2 mm to 50 mm size. Coal is commercially

Fire and Explosion Prevention in Coal Pulverizing Systems

Proper design and operation of the pulverized coal burners protects the pulverizing system from ignition from the furnace fire. The coal/ air mixture enters the furnace through a burner nozzle at velocities in excess of the flame speed. Thus, the flame front is held stable at a distance away from the end of the nozzle where the coal/ air mixture velocity has slowed and is equal to the
