pipe lance for a commercial furnace. Yeh et al.5) performed CFD studies of pulverized coal and blast furnace top gas (BFG) injection and found that coal burnout decreased with increasing BFG injection because the BFG consumed oxy-gen, reducing the amount of oxygen available to react with the coal. They also noted swirling of the blast air caused by

Pulverized Coal Injection in a Blast Furnace IspatGuru

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 pipe.

Influence of conveyance methods for pulverised coal

2018-9-26  Pulverised coal injection (PCI) is a widely adopted industry practice for reducing blast furnace coke rates. The conditions under which pulverised coal (PC) is injected and combusted, including the co-injection of natural gas (NG), can lead to complex combustion phenomena inside the blast furnace, which must be understood to provide improved furnace performance.

Understanding Blast Furnace Ironmaking with Pulverized The injection of the pulverized coal into the BF results into (i) increase in the productivity of the BF, i.e. the amount of hot metal (HM) produced per day by the BF, (ii) reduce the consumption of the more expensive coking coals by replacing coke with cheaper soft coking or thermal coals, (iii) assist in maintaining furnace stability

Design and start-up of Gary Works' pulverized coal

2021-1-2  A pulverized coal injection system began operation at the Gary works' blast furnaces on Feb. 1, 1993. This system is capable of processing more than 3500 tons of coal/day to eventually supply the furnaces at a 400 lb/NTHM rate. The start-up was aggressive with coal levels exceeding 200 lb/NTHM within two to five weeks on the furnaces.
