    摘要： A method for preheating a rotatable fluidizable bed (106) comprises rotating the bed chamber (112) slowly to cause the particles (114) to slowly tumble and mix. During tumbling, one or more burners (150, 160) extending into the chamber (112), heat the particles (114) until the desired operating or ignition temperature is reached. Temperature sensors (170) in thermal communication with the bed particles (114) sense the temperature and provide either an indication thereof or an initiating signal which, in the case of a rotating fluidized bed combustor (10), terminates preheating, accelerates the bed chamber (112) rotation to normal combustor (10) operating speed and/or introduces fluidizing air and/or fuel flow through the bed chamber (112).

    摘要： A coal fired combustor for a gas turbine engine comprises a centrifugal fluidized bed where the coal particulate is introduced radially inwardly toward the axis of rotation through the bed. A centrally mounted pipe which may be rotatable at a different velocity collects and distributes the gases generated by the combustion process and also serves to filter out the elutriated particles. Additives to the fuel for minimizing sulfur dioxide (SO.sub.x) and nitrogen oxide (NO.sub.x) may be added to the fuel prior to introduction to the bed so that the adverse effects of elutriation does not occur before sulfur adsorption.

    摘要： 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.
