Fluidized bed method and apparatus for producing a combustible gas
A combustible gas producer plant is described in which a finely divided inert particulate material fluidized bed is divided into a first, combustible-gas producing section and a second, heating section, to both of which sections fuel is fed. Heat transfer, by bed material migration, from the second to the first section sustains the reaction in the first section leading to the production of combustible gas. A diaphragm water wall divides and surrounds the volumes above bed sections and is part of a boiler generating steam used (optionally with added oxygen) to fluidize the first bed section. The steam is also used to fluidize the bed material at the boundary of the bed sections and prevent in-bed gas migration across that boundary. The second section of the bed is fluidized with air or an air/inert gas mixture. Fluidization is effected with sparge tubes and the plant may include evaporator, superheater and economizer sections for the boiler.
