Pulverized coal injection (PCI) is a recognized method of controlling costs in iron making. The blast furnace is a complex system, so the replacement of coke with pulverized coal is not as simple as increasing the injection rates, especially when one considers iron …
Pulverized Coal Injection. The injection of pulverized coal into a blast furnace has become the most important secondary fuel for iron making. The advantages of pulverized coal injection are obvious: Replacement of 30 to 40 (up to 50) percent of the coke charge; Substitution of existing oil or natural gas injection; Reduction of fuel costs
Coal injection system. Reduced pollution Coal grinding and injection systems are non-polluting systems. Injecting pulverized coal into a blast furnace reduces the overall pollution made by coke production. Increased productivity Installation of a coal injection system can increase productivity through improved operation of the blast furnace.
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.
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.
