Pulverized Coal Injection. Pulverized Coal Injection(PCI)was the earliest known form of injection into the tuyeres of a Blast Furnace,but it was not until the early sixties of the last century that PCI has been implemented successful y for hot metal production.Trials in several countries at this time had proved that the technology for pneumatic transport and injection of coal was available,but ...
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.

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.
Pulverized coal injection is an essential instrument for modern blast furnace ironmaking. The benefits of reducing coke consumption and increasing production are recognized by the industry. The Danieli Corus system is based on straight-forward physical principles to achieve equal coal to-gas ratios in front of the individual tuyeres.
facilities, injection equipment, etc.) in common. This means separate injection equipment must be installed and reducing agents can only be used at designated tuy-eres. To increase recycling, the gasification behavior of waste plastics should desirably be as similar to that of pulverized coal as possible. It is also necessary to pul-
Pulverized coal injection is a method for improving the performance of a blast furnace. Background. Iron is a metal which has fundamentally affected the way of life of human beings ever since the Iron Age. It is relatively abundant and can easily be extracted and modified due to its useful material properties, all of which results in low prices.
Producing electricity in coal power plants can take place in a number of ways with varying degrees of efficiency. In conventional coal-fired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C.
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 …

The Committee of Pulverized Coal Combustion and In-Furnace Reaction in BF was set up in 1993 as a cooperative research of the Japan Society for the Promotion of Science (JSPS) and the Iron and Steel Institute (ISIJ) to evaluate research initiative into this problem.
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.
of operating issues in the coal preparation system and in the furnaces, however, limit the types of coal that can be used and the maximum delivery rates to the furnaces, however.

A pulverized coal injection system consists of a pulverizing mill, a filtering system, storage tanks, and a blast furnace. Coal comes in through a bunker and is pulverized in a pulverizing mill. The pulverized coal is carried by hot air into a storage tank for drying, and the hot air is emitted to the atmosphere through a bag filter.
