    摘要: An installation comprising a combustion chamber having a device for introducing the mineral load and that is connected to a preheater, a combustion device to maintain the chamber at a temperature between 700° C. and 900° C., a treatment gas introducing device, the gas having a controlled carbon dioxide content in order to oppose the dissociation of the carbonate in the chamber and a device for removing the calcined mineral load guided into a cooler. The chamber also forms a fluidized bed. The treatment gas introducing device is supplied, at least partially, by a bypass duct, with some of the flue gases from the chamber coming from a device for discharging these gases into the atmosphere. This may be used in the production of a cement-type hydraulic binder.

    摘要: Method and apparatus for obtaining finely pulverized quicklime powder having high reactivity by calcining fine limestone powder, particularly, of particle sizes 1-100 micrometers. Coarse particles of inert substance, particularly, those having diameters of 100-1500 micrometers, are fluidized with high temperature gas to form a fluidized bed, and fine limestone powder is supplied into the fluidized bed. The fine limestone powder captured by the fluidized bed is calcined therein and the resulting quicklime powder is carried away by the stream of fluidizing gas and recovered with cyclone and bag filter. Coarse limestone may be used instead of or together with the coarse inert substance particles.

    摘要: The invention features methods and systems for producing commercial quality carbon dioxide (CO2) of 90% to +99% purity using, wet, fine particle limestone produced in a manufacturing operation, for instance, a limestone quarry as a feedstock to a multi-stage limestone calcination process. This process may be fueled with negative cost waste water treatment plant (WWTP) sludge, biomass, coal, or other low cost solid fuels. High reactivity lime product required in the an adjacent paper mill's PCC manufacturing plant is also produced, and steam and heated boiler feed-water is generated and exported to the mill's steam distribution and generation system as well as hot process water for use in the mill's manufacturing operation. The system for calcining fine particle limestone produced in a quarry manufacturing operation and converting it to lime and CO2 comprises a calciner and a combustor linked by a moving media heat transfer (MMHT) system or apparatus. The MMHT system or apparatus thermally links separate fluid bed combustion (exothermic) and calcination (endothermic) stages with a solid particulate media. The fluid bed calcination stage is fluidized with steam. The system further comprises a dryer/pre-heater that utilizes exhausted heat from the calcination stage.
