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 noncoking 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.
and in the furnaces, however, limit the types of coal that can be used and the maximum delivery rates to the furnaces, however. The blast furnace area has access to both high and lowpurity oxygen, but 8 Coinjection Of Natural Gas and Pulverized Coal in the Blast Furnace at High Levels: Field Test Results at USS/Gary, Gas
Also by producing less coke, more time would be available for repair and rebuilding of existing batteries. Coal injection started at Taranto blast furnaces Nos. 4, 2, 5 and 1 in September, October, November, 1991 and January, 1992 respectively. A central grinding and injection station supplies coal to the blast furnaces.
A threedimensional multiphase CFD model using an Eulerian approach is developed to simulate the process of pulverized coal injection into a blast furnace. The model provides the detailed fields of fluid flow velocity, temperatures, and compositions, as well as coal mass distributions during the devolatilization and combustion of the coal.
Pulverizers: Williams Roller Mills pulverize or granulate and air classify chemicals, minerals, coal, limestone, phosphate rock, pigments, tobacco, clay, and barytes. Roller mills are also capable of drying with the addition of a heater. Williams Direct Fired Mills pulverize coal and petroleum coke fuel for direct firing into boilers and kilns.
ROGESA was founded in 1981 and currently produces up to million tons of hot metal each year. The company continues to invest in the future with an eye to optimizing environmental protections with the relining of one blast furnace in 2016, the expansion of the coal pulverizing plant with a third coal pulverizer and the construction of a ...
May 10, 2013· Pulverized coal injection in a blast furnace. Pulverized Coal Injection (PCI) is a process that involves injecting large volumes of fine coal particles into the raceway of a blast furnace (BF). This provides not only a supplemental carbon source but also speeds up the production of liquid iron besides reducing the need for metallurgical coke ...
Blast Furnace Injection at ArcelorMittal. Granular Coal Injection Preparation System Two (2) Williams DF90 Roller Mill Systems with patented inert gas drying reduce 2" x 0 high volatile bituminous coal with % moisture, to minus 4 mesh at 60 TPH or 70% minus 200 mesh while simultaneously drying the coal to less than .5% moisture in a safe, inert atmosphere.
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 chemistry, fuel rates and furnace .

Nov 10, 2000· 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. The capacity of the furnace to consume these particles by solution loss is probably one ...
Pulverized Coal Injection (PCI) into the blast furnace through tuyeres together with oxygen enrichment affect coke properties and blast furnace operation. Using coke sampler at tuyere level, coke samples were collected and analysed at various coal injection rates .
Coal Pulverizer Maintenance Improves Boiler Combustion. Dec 1, 2015 Optimized coal pulverizer performance is a prerequisite for ensuring the best furnace combustion efficacy. Here are some solutions for overcoming commonly identified combustion problems. Coal pulverizers are the heart of a pulverized coalfueled boiler.
1. the process of firing a blast furnace with pulverized coal which comprises the steps of preparing a mixture of pulverized coal and carrier air in a pulverizing zone at a pressure sufficiently high to overcome the combined static pressure within said furnace and the pressure drop through the entire conveying system between said pulverizing zone and said furnace, maintaining said prepared ...
