ALL ABOUT BLAST FURNACE
Jul 16, 2017 · 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.
Pulverizer
The material to be pulverized is introduced into the center or side of the pulverizer (depending on the design). As the lower ring rotates, the balls to orbit between the upper and lower rings, and balls roll over the bed of coal on the lower ring. The pulverized material is carried out of the mill by the flow of air moving through it.
Pulverized coal burners
In burners of all three types, highdensity pulverized coal is injected through pipes (76 or 89 mm in diameter) with splitters at the end. Central and peripheral air passages have axial swirlers. Natural or coke gas is injected into burners via gas tubes .

Petcoke has become a competitive fuel, which has made it very popular in Process / Power boilers. Petroleum coke basically comes in two types named the fluid coke and delayed coke. Fluid coke is typically left with / contains about 5 % volatiles and because of its small particle size is not generally very suitable for combustion in AFBC boilers.
Kiln burners
The primary fuel is typically pulverized coal or coal+coke, with the option to burn natural gas or fuel oil. Either natural gas or fuel oil can be ignited directly by the integral ignition system. Typically, natural gas or fuel oil is be used to heat up the rotary kiln and then ignite the coal flame, but either may be used to fire the kiln up ...

Dec 30, 2004 · The current work investigates the performance of petroleum coke (PC) as a blended fuel under pulverizedfuel combustion conditions. Three fullscale combustion experiments were carried out: a pure Carboniferous, high volatile bituminous coal and two blends of this coal with different proportions of PC. The samples studied included feed fuels and .
Fluid and FlexiCoking | FSC 432: Petroleum Refining
Fluid coking can process heavier VDR and gives a higher distillate yield (and lower coke yield) than delayed coking. Figure shows a schematic diagram of flexicoking. A gasifier is added for conversion of some or all coke produced in the coker in .
What is meant by pulverized coal?
May 11, 2020 · A pulverized coalfired 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.
Rapid Pyrolysis of Pulverized Coal for the Preparation of ...
By rapid pyrolysis of pulverized coal in oxygen and steam atmosphere, powder activated coke (PAC) nanostructured carbon material was derived by one step. Then, nitrogen adsorption measurement, scanning electric measurement (SEM) and Fourier transform infrared spectroscopy (FTIR) test were conducted to analyse the detail characteristic of the obtained PACs.
Coke :Manufacturing from Coal
Non byproduct coke ovens burn the hydrocarbon off gasses produced by the coke making process to drive the carbonization process. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. Coke may be used to make fuel gases.
