- Description
- Differences of peak temperatures, coal heating rates and residence times between Pulverised Coal Injection (PCI) into blast furnaces and a Drop Tube Furnace (DTF) may significantly influence the combustion performance of coals in the two rigs. This paper has conducted a comprehensive comparative study on the coal combustion performance of seven coals in a DTF and a PCI test rig where the coals are injected at the as-ground size distribution. The measured burnouts from both the DTF and the PCI rig produced linear trends as a function of coal rank as indicated by the Volatile Matter (VM) content. The range of burnout produced in the DTF tests is significantly greater than that in the PCI rig tests and consequently the DTF burnout data have a steeper slope, with differences in volatile matter extent the possible reason.
