ABSTRACT:
A rotary fluidized bed combustion system in which air and particulate solid fuel are introduced and mixed. The mixture is caused to rotate to generate an artificially induced gravitational field. Some of the air is introduced so as to flow inwardly at a later time in a manner such that it interacts aerodynamically with the fuel particles which are propelled outwardly by the centrifugal forces caused by the artificial gravitational field, thus generating a fluidized bed effect for the particles. The fuel and air chemically react and combustion results. As the fuel particles burn, their sizes decrease and they are slowly pushed inwardly by the gas flow which is forced to follow an elongated path around generally conical surfaces of decreasing radii, toward the exhaust vent. The residence time of the fuel particles, inside the combustion region, is thereby increased. The combustion effectiveness of the fuel is thus considerably improved and no recycling of the unburned fuel particles is then required.
