1/12/2008 · Again, one has to be aware of the difference between FBC and grate-firing if the same method was used in grate-firing boilers. Coal ash could also be used as a kind of additives. It was found that during co-firing of straw and coal there seemed to be a significant capture of K from the straw, by the coal ash, which was observed in different utility boilers.

Direct co-firing is a simple approach and the most common and least expensive method of co-firing biomass with coal in a boiler, usually a PC boiler. As shown in Fig. 4.1, in direct co-firing technology biomass is fed directly into the furnace after either being milled together with the base fuel ( Fig. 4.12A ) or being milled separately ( Fig. 4.12B ) The fuel mixture is then burned in the
