In order to burn antracitic coal in Fujian Province for circulating fluid bed(CFB) boiler

an auxiliary ignition system of bituminous coal as well as a coal feeding mode of blending feed coal with returned materials has been adopted

and through enhancing temperature in dilute-phase rejion and allocation of high effective cyclone separater

so as to solve the problem of difficult ignition and difficoult burnaway for antractitic coal.Results of examining boiler performance show that the thermal efficiency of boiler to be 99.75%

reaching the designed value.
