kilns, industrial boilers, and coal-fired heating plants, are good candidates for co-firing as well. Coal versus Biomass One of the reasons biomass is a good candidate for co-firing with coal is that both biomass and coal are solid fuels. There-fore, equipment designed to burn coal should be able to easily use biomass as well—you would think.
