摘要： Process and furnace for producing clinkered cement pellets from pellets of cement-forming batch materials without melting, fusion and agglomeration of said pellets. The furnace comprises an elongate vertical suspension shaft having top, intermediate and bottom portions. Pellets are fed at the top and heated to calcining temperatures before exiting the shaft into a pre-clinkering zone beyond the bottom. The pellets are heated to pre-clinkering temperatures and deposited on a porous pellet bed through which cooling air is forced to control the exothermic clinkering reaction and to regulate the speed at which the pellets migrate through the shaft.

摘要： The invention relates to a method of reclaiming contaminated industrial sand including the steps of subjecting the sand to the influence of heat in a fluidizing bed, forcing sand fed to said bed to follow a flow path including a plurality of generally heightwise directed path portions including at least one generally upwardly directed path portion and at least one generally downwardly directed path portion. In an example of the invention, the heat is applied to the sand in a first group of path portions and the sand is cooled in a second group of path portions.

摘要： The specification describes a wall arrangement for heated chambers in which arrangement the walls are provided with gaps between sections of them enabling expansion of the walls when the temperature of the chamber is increasing. The particular arrangement further provides means for preventing inert material packing said gaps so as to prevent expansion of the walls. The invention is of particular use with wall arrangements housing fluidized beds in which the inert particulate material forming the bed may enter the gap between the wall sections. As described the means for preventing the inert material packing the gaps comprises gas injector means arranged to force gas into each gap and thereby keep any inert particulate material that may enter the gap in a fluidized state.

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 fluidized bed-furnace for burning partly dehydrated sludge comprises a furnace housing having a bottom forming a surface for a fluidized bed. Side walls extend upwardly from the bottom and above the fluidized bed in defining combustion chamber above the bed. An inlet for sludge on one side of the housing extends into the side walls and a discharge for the sludge on the opposite side of the housing extends outwardly from the side walls. The bottom is made of a plurality of steps arranged at distinct elevations in descending order from the inlet to the outlet or discharge. Each step portion includes a grate having a wind box associated therewith through which heating gases and including combustion air is directed upwardly through nozzle elements which extend in openings of the grate. The entire bottom with all of the step portions are advantageously supported on a support structure which is suspended at the bottom of the furnace and it is advantageously removable from the bottom.

摘要： A system and method for the fluidized direct reduction of iron ore concentrate powder. A two-phase fluidized bed is used for the direct reduction of iron ore concentrate powder. Each phase of the fluidized bed is formed by a bubbling bed and a circulating bed. Use of serial-connection processing involving gas and of high-gas-velocity processing of the circulating bed increase the gas utilization rate and the reduction efficiency of single-phase reduction. Once reduced gases are subjected to preheating, each gas is sent into an initial reduction phase and a final reduction phase so as to implement reduction of minerals. Use of mixed-connection processing involving gas appropriately reduces processing pressure. Hot flue gas produced by combustion in a gas heater is sent to a mineral pre-heating system that is used for pre-heating iron ore concentrate powder.
