摘要： This invention relates to manufacturing briquettes, pellets and shapes from recycled asphaltic limestone powder derived from waste residential roofing products. Briquettes and pellets are manufactured through a densification process at varying temperatures, creating recycled asphalt pellets, asphalt limestone pellets and bio mass and coal fines briquettes. Various shapes, including curbs and posts, are manufactured through heat and pressure in molds. Seawalls, walkways and wall panels are manufactured by blending asphaltic limestone powders with polymer resins and extruded or pultruded into shapes.

摘要： Air pollution includes emissions from two sources: fixed sources and moving sources. A fixed source could be an electric power generation facility or a lime kiln. A moving source can be a tail pipe such as one on an automobile. The fixed source's emissions are redirected downward into a depleted hydrocarbon reserve through an injection well. The moving source is attached to a Carbonator which takes calcium oxide from the lime kiln and carbon dioxide from the moving source to produce calcium carbonate. This removes two sources of air pollution, first the use of the Carbonator system to remove Carbon Dioxide Emissions into the Atmosphere as described in the Application and secondly the total injection of all smokestack effluents into depleted reservoirs, removing the smokestack and in an electrical generating station HVDC transmission lines are run to the displaced smokestack, and is thus a solution to air pollution.

摘要： An arrangement for burning lime mud into lime in a lime kiln. The lime mud flows counter-currently to flue gases from a feed end to a firing end and the fuel used is flue gas that is produced by gasifying a fuel in the presence of combustion air in a gasifier. The combustion air for gasification is preheated with heat generated in lime mud combustion. The arrangement is provided with a conduit between the lime kiln and the gasifier for leading air from the lime kiln into the gasifier as combustion air. At least a portion of the combustion air for gasification is preheated with heat generated in the lime mud combustion so that air is led into cooling of lime obtained in the combustion and further into the kiln, from or through the firing end of which air is taken into the gasification.

摘要： The present invention is directed to a method of continuously calcining a limestone particle mix comprising a fine fraction of limestone particles and a coarser fraction of limestone particles. The limestone particles heat treated in a flash calciner in which the mixture is entrained and heated in process gas for an amount of time sufficient to fully calcine the fine fraction but not the coarser fraction. The process gas is separated from the heated limestone mixture. The mixture is directed to a retention vessel in which the mixture is retained for an amount of time sufficient to fully calcine the coarser fraction utilizing the process heat present in the limestone mixture. No external heat needs to be added to the retention vessel during the retention step to promote calcination.

摘要： The system according to the invention for thermally processing lumpy solid material substantially comprises a preheating device, a furnace and a separation or classification device which is arranged therebetween and which has a coarse material outlet connected to the furnace and a fine material outlet. The furnace and the preheating device are connected to each other by means of a gas/solid material line which is arranged so as to be inclined relative to the vertical, the furnace exhaust gases being introduced at the end of the gas/solid material line at the furnace side and the preheated solid material being supplied at the end at the preheater side. The separation or classification device is connected to a bypass line which branches off from the gas/solid material line so that at least a partial amount of the preheated solid material can be branched off via the bypass line by means of gravitational force and can be supplied to the separation or classification device.
