| Abstract: | In order to increase boileroutput and utilize local coal more efficiently,a 10 t/h BFB boiler burning Fujiananthracite was retrofitted with several special techniques,in terms of underbed feeding ofrecycling fly ash,vortexing secondary air injection,continuous bottom ash removal andadding immersed tube surface. The boiler performances before and after the retrofittingwere measured and compared.The retrofitting was completely successful.The technique usedand experiences obtained in the retrofitting can be widely applied in industrial BFBboilers. |
