TVA along with MicroFuel Corporation, Research-Cottrell Research and Development, and Duke/Fluor Daniel have been selected for the Department of Energy's (DOE's) Clean Coal Technology IV program to demonstrate Micronized Coal Reburn technology for control of nitrogen oxide (NO{sub x}) emissions on a 175 MWe wallfired steam generator at its Shawnee Fossil Plant. This retrofit demonstration is expected to decease NO{sub x} emissions by 50 to 60 percent. Up to 30 percent of the total fuel fired in the furnace will be micronized coal injected in the upper furnace crating a fuel-rich reburn zone. Overfire air will be injected at high velocity for good furnace gas mixing above the reburn zone to ensure complete combustion. This paper will focus on Micronized Coal Reburn technology and the plans for a full-scale demonstration at Shawnee.
