Oct 04 2018 · Coal explosibility affects the safety during the injection of coal in the BF Reactivity – The reactivity of coal refers to reacting ability of coal with carbon dioxide CO2 or water vapour H2O under certain conditions After pulverized coal injection in the BFe part of the unburned coal char reacts with CO2 while ascending with the gasGet Price
Pulverised coal injection PCI is a well established technology It is practised in most if not all countries with cokebased BFs and new BFs are nearly always fitted with PCI capability Waste plastics injection WPI is less Injection of coal and waste plastics in blast furnaces 5 commonly carried out with only a few ironmaking plants inGet Price
PCI plant Coal injection system Reduced pollution Coal grinding and injection systems are nonpolluting 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 blastGet Price
The most common heat transfer method for coalfired boilers is the watertube method in which the hot combustion gases contact the outside of the heat transfer tubes while the boiler water and steam are contained within the tubes Coalfired watertube boilers include pulverized coal cyclone stoker fluidized bed and handfed unitsGet Price
May 10 2013 · Fig 1 Typical flow sheet of pulverized coal injection in blast furnace The process of coal injection The PCI process is based on the simple concept of carrying the finely ground pulverized dried coal by a conveying gas normally nitrogen to the BF where it is distributed to different tuyeres and injected through a lance in the blow pipeGet Price
