Pulverized coal (pulverized fuelpf) has been fired in rotary cement kilns (see Kilns) and boiler furnaces (see Boilers).The latter are basically boxes lined with tubes in which water is evaporated and contain a water/steam mixture. The coal is pulverized to a fine powder, usually so that 70% is less than about 75 μm in size, before being carried by part of the combustion air stream to the
Lazard does not explicitly define their ranges with and without CCS thus, the high end of their pulverized coal and IGCC ranges and the low end of their IGCCCCS range are assumed to be the middle of the full reported range.All sources have been normalized to the same dollar year. Costs vary due to differences in system design (e.g., coal rank), methodology, and plant cost definitions.
