Waste biomass from production process co-firing …

Fluidised bed combustion is an efficient and low pollution combustion technology used in power and steam generation processes. As wide fuel adaptability, the use of a FBC furnace allows the combustion of many forms of solid fuels. Therefore biomass co-firing through the FBC boilers can substitute for up to 30% of the coal used in the boiler.
