摘要： A system includes a standpipe for receiving a flow of solids therethrough, the standpipe having at least one inlet configured to receive a gas for decreasing a solids-to-gas ratio of the flow, a sealpot having an inlet fluidly coupled to the standpipe and an outlet fluidly coupled to a riser, the sealpot being configured to fluidize the solids received from the standpipe and to transport the solids to the riser, and a drain device fluidly coupled to an outlet in the standpipe, the outlet being located upstream from the inlet of the sealpot. The drain device is configured to remove the excess gas from the flow of solids within the standpipe to increase the solids-to-gas ratio of the flow prior to the solids entering the sealpot.

摘要： An external bed type double-fluidized bed system for preventing boiler contamination includes a fluidized bed combustion furnace, a cyclone separator, a coal ash distributor and a fluidized bed pyrolysis furnace. The fluidized bed combustion furnace is connected with the coal ash distributor, the coal ash distributor is connected with the coal ash inlet on a side wall of the fluidized bed combustion furnace through a return feeder with which the coal ash outlet of the fluidized bed pyrolysis furnace is also connected through an external bed, and the return feeder is connected with the fluidized bed combustion furnace. A fuel coal is pyrolyzed in the fluidized bed pyrolysis furnace at a temperature to volatize alkali chlorides into a pyrolysis gas, thereby reducing the content of the alkali chlorides contained in the coal in the fluidized bed combustion furnace and relieving the contamination to a convective heat-absorbing surface.

摘要： A rotary bottom ash regenerating (RBAR) system [100] comprises a cylindrical body [110] that receives ash [17] containing reactant particles [10] that are partially reacted limestone compounds having unreacted cores [13] from a furnace. Sensors [140] sense physical parameters within the cylindrical body [110]. A controller [170] receives the output of the sensors [140] and information indicating the amount of unreacted core [13] and causes a fluid actuator [135] to spray a proper amount of regeneration fluid regulator [135] from a plurality of spray nozzles [131] to different locations within the cylindrical body [110] to regulate the temperature and to cause the reactant particles [10] to have a require content of regeneration fluid. This causes the reactant particles [10] to be regenerated and reused. This results in a lower limestone costs and less overheating of ash handling systems.
