Pulverized Coal Injection (PCI) using the dense-flow method. The Küttner developed and perfected dense-flow method offers several advantages over a lower-density system. Higher injection rates are achieved with simultaneously lower coke rates, which can optimize the fuel costs of the blast furnace.
Pulverised Coal injection into the blast furnace provides the operator with an option of reducing consumption of the more expensive variant of carbon – metallurgical coke. But metallurgical coke has other useful mechanical duties to perform in the furnace …
There are several configurations for commonly used pulverised coal furnaces, which can impact ash formation, but the primary advantage of pulverised coal combustion is the very fine nature of the fly ash produced. In general, pulverised coal combustion results in approximately 70–90% fly ash, and the remainder is coarser bottom ash or boiler ...

Pulverized Coal Injection (PCI) coal. Used in steelmaking, but it is not indispensable like met coal. It is a softer, non-coking coal which is pulverized and injected into the blast furnace to supply heat, which in return reduces energy use and emissions.
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.
At the tuyere inlet of blast, additional oxygen and pulverized coal are given by their inflow rates. The blast flow rate is fixed and pulverized coal and charcoal are iteratively calculated to reach the aimed pulverized coal and charcoal injection rates, which are specified at …
Injection of pulverized coal in the blast furnace (BF) was initially driven by high oil prices but now the use of pulverized coal injection (PCI) has become a standard practice in the operation of a BF since it satisfy the requirement of reducing raw material costs, pollution and also satisfy the need to extend the life of ageing coke ovens.

23/2/2018· Watch how a Pulverized coal feeding & handling system ensures proper air-fuel ratio and coal finesse consistency for better combustion. United Nations Development Programme, India partners with ...
pulverized coal injection Reliable, efficient and accurate injection of auxiliary reducing agents is vital for cost effective blast furnace operation. Paul Wurth is involved in the development and application of all forms of gaseous, liquid and solid reducing agents injection via the hot blast tuyeres.
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 for reactions in the blast furnace.
