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.
beneficial effects on the Blast Furnace process. Pulverized Coal Injection Raw coal is screened and processed to remove tramp materials and is stored in raw coal bins. Raw coal is pulverized and dried and then pneumatically conveyed to filters in a once–through system. The pulverized coal is then deposited in a single reservoir and stored under inert conditions. From the reservoir, the ...

The injection of pulverized coal is the most common method to reduce coke consumption and increase the rentability of your iron production in the blast furnace. Küttner as technological and market leader is offering all‐in‐one solutions spanning from raw coal mixture to injection devices.
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 ...
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.
2015-04-08· Complete working process, working flow of pulverized coal burner for asphalt plant or other heating system.
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.
Pulverized coal injection process should include the raw coal storage and transportation systems, milling systems, coal handling systems, injection systems, gas systems and coal metering system, the latest design of pulverized coal injection system also includes the entire spray coal system computer control center.

Pulverized Coal Injection - Claudius Peters. Advantages of Pulverized Coal Injection 3, manufacture and commissioning of materials handling and processing systems for the gypsum,, PCI plant Coal,
Pulverised coal injection – optimising the blast furnace process The injection of reduction agents via tuyeres in blast furnace operation is now common practice worldwide (see Figure 1). The benefits of reduced coke consumption and increased production due to the removal of nitrogen from the blast with increasing oxygen enrichment have been recognised by the industry[1, 2]. In choosing an ...
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.
The BFGCI process uses granular coal, which is cheaper to produce than the pulverized coal required by many other blast furnace coal injection technologies. The BFGCI technology has
