The boiler is a CFB boiler of high temperature & high pressure parameter, single drum, natural circulation, outdoor arrangement, steel structure suspension and HT insulated vortex cyclone separator.The steel structure has three sections, one for furnace, one for cyclone separator and reinjection system, and another for back-end pass.The furnace is of whole water-cooling membrane wall structure, 6 SH steam panels and 6 water-cooling panels are arranged at the upper furnace along width direction, the water-cooling air distributor and air plenum are arranged at the furnace bottom and 4 ignition oil burners are arranged on the bed with 4 ignition oil burners under the bed.

2 HT insulated cyclone separators lie between the furnace outlet and back-end pass. The rejector under the cyclone separator injects the separated materials back to the furnace.In the back-end pass, HT superheater, LT superheater, economizer and air preheater are arranged in turns. The membrane enclosure wall superheater is adopted for the back-end pass from turning chamber to LT superheater. Two stage water injection attemperator is arranged in superheater system.The air is supplied in two stages. The primary air enters the furnace through the air distributor and water cooling air chamber at the bottom, and the secondary air enters the furnace through two layers at the front and rear wall.Front wall coal feeding mode is adopted, 4 coal feeding holes are arranged at lower of front water cooling wall along width direction. 3 slag-off holes are arranged at air distributor, and slag-off holes at outboard are arranged with water cooling rotary drum slag cooler.HT insulated cyclone separator and slag leakage prevention type inter opposite flow column nozzle button are adopted according to characteristics of Indonesia fuel. HT insulated cyclone separators can capture thin particles in air which can highly increase separating efficiency; and inter opposite flow column nozzle have functions of antiwear and slag leakage prevention. Both above make sure that boiler can be long-term operated reliable.
