A steam generator in which a main boiler is provided and at least one fluidized bed furnace is connected with the main boiler and is operated independently of the furnace of the main boiler. The fluidized bed furnace is connected with the main boiler underneath the boiler funnel. The tubes of the boiler funnel are partially fanned out and form flue gas passages, through which the flue gas of the fluidized bed furnace flows into the combustion chamber of the main boiler.

A charged adsorbent is accommodated in a desorbing vessel and in an intermediate container which communicates with the desorbing vessel. The charged adsorbent is desorbed in the desorbing vessel by contacting the same with a heat carrier, such as with hot sand, and a desorption gas which develops during the desorption of the charged adsorbent in the desorbing vessel is passed through the charged adsorbent accommodated in the intermediate container to capture at least one component of the desorption gas in the charged adsorbent present in the intermediate container. The purified desorption gas is withdrawn from the intermediate container, and the regenerated adsorbent is gradually discharged from the desorbing vessel and the supply of the adsorbent in the desorbing vessel is replenished by charged adsorbent from the intermediate container. The desorption gas is cooled during the passage thereof through the charged adsorbent present in the intermediate container. The magnitude of the temperature reduction of the desorption gas may be controlled by controlling the rate at which the desorption gas is discharged from the intermediate container, such as by resorting to the use of an adjustable vane. The adsorbent in the intermediate container may be confined by gas-permeable walls through which the desorption gas enters and leaves the adsorbent present in the intermediate container.

Method of regenerating adsorbents

A method and apparatus for separating undesirable components from a waste gas by adsorption of the components onto a granular adsorbent. The gas is caused to flow serially through two distinct side-by-side layers of adsorbent both moving parallel to one another in a direction perpendicular to the direction of gas flow. The adsorbent material is so controlled that the particles of the second layer to be contacted by the gas are less loaded with impurities than the particles of the first layer. In one embodiment, this result is achieved by moving the second layer faster than the first layer.
