Abstract

resumo patente de invenção: "combustão de biomassa". a presente invenção refere-se a um meio e um método para, pelo menos, injetar partículas mitigantes na região de combustão (bola de fogo) de uma caldeira de biomassa (1). as partículas mitigantes atenuam os problemas de aglomeração de escória, incrustação e corrosão causados pelas cinzas de biomassa ao, pelo menos, capturar as cinzas de biomassa. as partículas mitigantes capturam as cinzas de biomassa ao formar um vínculo físico com as cinzas de biomassa tal que elas aderem à superfície das partículas mitigantes. ao injetar as partículas mitigantes na região de combustão, a oportunidade de capturar as cinzas de biomassa é otimizada.patent summary: "biomass combustion". The present invention relates to a means and method for at least injecting mitigating particles into the combustion (fireball) region of a biomass boiler (1). Mitigating particles alleviate the slag agglomeration, scale and corrosion problems caused by biomass ash by at least capturing biomass ash. Mitigating particles capture the biomass ashes by forming a physical bond with the biomass ashes such that they adhere to the surface of the mitigating particles. By injecting the mitigating particles into the combustion region, the opportunity to capture the biomass ash is optimized.
