A plant for chemical or physical treatment of granular solids includes a fluidized-bed reactor, a solids supply conduit and a central gas supply tube. A cooling tube is disposed relative to the gas supply tube so as to form an annular cooling duct, which is configured to cool the gas supply tube and the process gas and is connected with a coolant source configured to supply a coolant with a temperature of below about 400&#xb0; C. Outlet openings are disposed in the cooling tube. The fluidized-bed reactor is a Venturi reactor in which the cooling tube opens into a flared portion with the outlet openings connecting the annular cooling duct with the reactor interior. The cooling tube adjoins the gas supply tube and extends substantially parallel to the flared portion of the reactor.

Process and plant for the thermal treatment of fine-grained solids

A process for at least one of a chemical and a physical treatment of fluidizable substances in a reactor. The process includes introducing a hot gas into an interior of the reactor through a gas supply tube and cooling at least one of the hot gas and the gas supply tube with a coolant. The cooling is performed by contacting the hot gas with the coolant so as to provide a temperature of a wall of the gas supply tube at least 50&#xb0; C. lower than a temperature of the gas at an inlet of the gas supply tube facing away from the interior of the reactor.

A process for the combustion of a liquid in a combustion chamber includes atomizing liquid sulfur using a rotary atomizer and introducing the liquid sulfur into the combustion chamber. The liquid sulfur is charged onto an inside of a cup. The cup is rotated so as to form a liquid film on the inside of the cup and so that parts of the liquid film are radially flung off from an edge of the cup edge into the combustion chamber. The rotational speed of the cup is varied so as to control a thickness of the liquid film in the cup to between 200 and 1000 &#x3bc;m. The liquid sulfur is evaporated and subsequently burnt in the combustion chamber.
