    摘要: A method of feeding at least one of light, fine, volatile and moist fuel into a furnace of a circulating fluidized bed boiler. Fuel is introduced into the furnace and is combusted in the presence of a fluidized bed material to form flue gases. The fluidized bed material is circulated both inside the furnace in an internal circulation in which bed material returns along walls of the furnace down to the bottom of the furnace, and outside the furnace in an external circulation that includes at least a solids separator arranged in flow communication with the furnace. Bed material is separated from the flue gases in the separator. The flue gases are removed from the separator for further treatment. The separated bed material is returned to the furnace. Circulating bed material from at least the internal circulation flowing down along the furnace walls to a return flow is collected, and the return flow is introduced in a consolidated form into communication with the fuel being introduced in the furnace, so that the bed material return flow and the fuel flow are mixed together and flow downwards in the furnace. This increases the residence time of the fuel in the furnace.

    摘要: Gas with entrained particles, such as high temperature and pressure gas from a pressurized circulating fluidized bed reactor, is filtered using a vessel having a gas inlet, cleaned gas outlet, and filtered particles outlet. A pulse of cleaning gas is periodically or intermittently directed to the filters to dislodge particles which have been filtered and collected on the filters. Shrouds, having tubular, parallelepiped, zig-zag, or honeycomb configurations, are provided surrounding relevant portions of the filters to prevent dislodged particles from being entrained in gas passing to other filters, and instead directing the dislodged particles toward the vessel particles outlet. The shroud walls may have openings in them which allow gas to be filtered to pass through them, but prevent dislodged particles from passing through the openings. The filters may be mounted in hollow tubular or parallelepiped ducts in such a way that the ducts have smooth outer walls, and the shrouds may be substantially concentric with the ducts. When individual cleaning gas pulsing devices are associated with filters, the shrouds may include separate impingement and material collecting portions.

    摘要: A nozzle arrangement for a fluidized bed gasifier or combustor. The nozzle arrangement includes a nozzle piece attached to a nozzle tube for forming one entity with the nozzle tube, which nozzle piece includes a nozzle chamber and a horizontally extending nozzle channel ending to a blow opening of the nozzle. The nozzle chamber and nozzle channel are limited from above by a lid. The nozzle arrangement further includes a protecting cover attached outside the lid for minimizing cooling of the outer surface of the nozzle piece due to fluidizing gas blown through the nozzle into the fluidized bed gasifier or combustor.
