| Abstract: | Making use of the oxygen-film enrichment technology,an experimental study on combustion-supporting technology,by local oxygen enrichment,has been conducted on a 150t/h pulverized coal fired boiler.Test results show,that the technology effectively solves problems of coking and high temperature corrosion in furnaces,reduces the combustible content in both slag and fly ash,raises the boiler's thermal efficiency,lowers NO_x emission and improves combustion stability during low load operation without oil injection. |
