What minimum coal particle size is necessary for micronized coal to work What happens in the closed spaced convection passes of a gas/oil fired boiler when burning coal This paper details combustion research undertaken by Old Ben Coal Company and performed by Riley Stoker Research Center to answer these questions. Furnace heat flux / temperature profiles are investigated and compared to No.6 oil firing. Ash deposition and aerodynamics are investigated. A unique observation of the effect of excess O{sub 2} on heat flux is also described as a result of this testing. Finally, conclusions are drawn regarding the use of micronized coal as a substitute fuel for gas/oil designed boilers.
