Abstract

A fluid-bed furnace has at least one combustion chamber housing a bed of incombustible particulate material to be fluidised when burning fuel fed thereto. Bed fluidisation is by forced release in the incombustible material of combustion promoting gas, normally air, from a plenum chamber (38) arrangement externally of the bed proper at a side or end thereof to save overall height. Furnace exhaust gas is returned to the bed for additional fluidising and heating purposes and release (53) within the bed of such returned exhaust gas is at a position higher than normal combustion promoting gas. Other features include an auxiliary burner within the combustion chamber to consume fine fuel material lifted from the bed in operation; insulation of at least the normal combustion promoting gas plenum chamber externally by incombustible bed material and/or internally by refractory lining; end tapering of bed traversing gas feed pipes to reduce expansion resistance; and a removable end plug in the latter pipes to ease cleaning thereof. <IMAGE>
