Abstract
This invention relates to fluidized bed furnaces. There is an increasing interest in furnaces in which the fuel is burned in a bed that is maintained in a fluent condition by combustion air supplied to the bed, and a fluid to be heated is passed through heat exchange tubes disposed within the bed. Interest has so far centered on the use of water as the fluid but this presents problems, especially at start-up and shut-down when it can be particularly difficult to ensure that the heat exchange tubes do not become dry and overheated.
