Abstract

See full text

A non-mechanical valve arrangement for use with circulating fluidized bed (CFB) boilers has a CFB reaction chamber and a bubbling fluidized bed (BFB) within an enclosure in the lower portion of the CFB reaction chamber, the BFB containing an in-bed heat exchanger (IBHX). Solids flowing from the BFB enclosure to the CFB reaction chamber may be controlled using one or more non-mechanical valves. Each non-mechanical valve is independently controlled using independently controlled fluidizing means. The non-mechanical valve has collectors to collect solids backsifting into the fluidizing means of the valve. Agglomerates are removed which could block the valve. Channel walls parallel to the direction of solids flow through the valve opening may be provided to reduce external interference with local fluidization to maintain the proper functionality of the non-mechanical valve.
