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 ...
Development of Waste Plastics Pulverization for Blast Furnace Injection circulation in the raceway, and as a result, gasification ... means separate injection equipment must be installed and reducing agents can only be used at designated tuy- ... that of pulverized coal. In the blast furnace.
safety interlocks for the coal injection plant. Keywords: Blast Furnacés Tuyeres; Straight Pipe; Hot Air Flow; Coal Injection 1. Introduction The aim of this work is to create a valid calculation me- thod to obtain a correct adjustment for the Delta P flow transmitters used in a special blast furnace equipment known as Straight Pipe Venturi (SPV).
The injection powder conveying pipe of the two groups connected to a main pipeline which reached to the blast furnace platform, and to inject before each blast furnace tuyere. 3.2 String tanks injection. Below the coal powder bin equipped 1 set of rotary feeding device, it is the core equipment used for the metering, control and injection.
Oct 21, 2018· Pulverized coal injection (PCI) is a well-established technology for hot metal (HM) production in a blast furnace (BF). It is practiced in most of the BFs and all the new BFs are normally built with PCI capability. The composition and properties of the coal used for injection can influence the operation, stability and productivity of the BF ...
In blast furnace ironmaking, efforts are made to decrease the coke consumption mainly by increasing the pulverized coal injection rate. This will cause changes in in-furnace reduction conditions, burden distribution and demands on raw material strength, etc. In order to maintain stable operation and minimize material losses
injection of granular coal into blast furnaces began in 1982 on the Queen Mary Blast Furnace at the Scunthorpe Works.('*2) The objective of the development work was to inject granular coal into the furnace and test the performance of the Simon-Macawber equipment with a wide
Modernization of existing blast furnaces and surrounding areas. Cast house floor design including water cooled and air cooled troughs, tilting runners, and fume collection system. Bell-less top and CRM rotary distributor. Lowprofile hydraulic mud guns and tap hole drills (including soaking bar technique). Pulverized coal injection.
In addition, the relative cost of coal would be significantly lower than the cost of coke it replaced. This lead to the decision late in 1991 to install pulverized coal injection (PCI) equipment for all of Inland`s blast furnaces.more » « less
