    (54) METHOD AND APPARATUS FOR OPTIMISING OPERATION PARAMETERS OF A BIOMASS BOILER


    (57) The present invention relates to a method for optimizing operation parameters of a biomass boiler, wherein said biomass boiler burns a plurality of biomass fuels to release heat and generate ash, said method comprising: providing fuel information of the biomass fuels and a target boiler load; generating a series of design operation parameters of the biomass boiler; calculating, based on the fuel information of the biomass fuels and the target boiler load, unburned carbon content in said ash for the design operation parameters; and identifying optimized operation parameters among the series of design operation parameters which correspond to the minimise unburnt carbon content. The present invention enables efficient adjustment of biomass boiler operation to adapt to the adjustment of biomass fuel mixture.
