About Pulverized Coal Injection (PCI): PCI is a process which involves injecting large volumes of fine coal particles into the raceway of the blast furnace (BF). It is an essential instrument for modern blast furnace ironmaking. PCI provides auxiliary fuel for partial coke replacement and has proven both economically and environmentally favourable.

a pulverizer so that the coal emerging from the pulverizer will consist of 70 to 80% particulate that will pass through a 200mesh screen sieve (that is, particles with a diameter of 74 km or less). High temperature air from the clinker cooler is often used to dry the coal and convey it from the pulverizer to the burning pipe in the kiln.

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.

How Do You Pulverize Coal? Coal is crushed to desired fineness between spheres or cylindrical rollers. After that, air from the boiler is heated to around 330°C (650°F). The raw coal is then fed into the pulverizer where it is ground into fine coal particles. What are the Advantages of Pulverized Coal?

causes less feeder hopper bridging and plugging problems. Coal feeders provide coal to the coal pulverizers (mills) where the 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 ...

The pulverizing process is carried out on an ondemand basis by devices called pulverizers (or mills), which are the key element of the PF system. The purpose of the pulverizers is the size reduction of incoming coal from a typical top size of between 50 and 75 mm down to a size distribution that measures around 70% (<75 μm).
