Pulverized 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.
In order to reduce the cost of running blast furnaces (BFs), injected pulverized coal is used rather than coke to fire BFs. As a result of this, unburned fine materials are blown with the gas into the bosh and dead man areas with possible detrimental effects on gas flow and permeability of the coke column.
Mathematical modelling of pulverized coal furnaces Resumen The aim of this paper is to set and numerically solve a system of equations that models the processes that occur into a pulverized coal furnace. A simple combustion model consisting of six chemical reactions including vaporization and volatilization is introduced.

Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions.
There is also known a furnace for pulverized fuels, named after its inventor Burg furnace. The chamber f the Burg tiring system also forms a whirl-current furnace, however, with inlets for secondary air distributed equally over the entire circumference through which the air enters in the direction of the rotation of the burning mixture.

Pulverized coal (pulverized fuel-pf) has been fired in rotary cement kilns (see Kilns) and boiler furnaces (see Boilers). The latter are basically boxes lined with tubes in which water is evaporated and contain a water/steam mixture.
Pulverized Coal Injection (PCI) System for Blast Furnaces. In the past, reactions within the blast furnace were stimulated by injecting heavy oil, as auxiliary fuel, along with the blasts and oxygen. The heavy oil was replaced by pulverized coal after the oil crisis. This made it possible to use cheap coal, such as non-coking coal.
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.
