摘要： A method for utilizing landfill-prohibited solid hazardous waste material as an energy source in a cement kiln is provided. The method comprises obtaining landfill-prohibited solid hazardous waste materials suitable for use in a cement kiln, combining the solid waste materials with a liquid fuel in a milling apparatus to form a mixture, grinding the mixture in the milling apparatus in a manner reducing the particulate size of the solid hazardous waste material to form a fuel slurry, and delivering the fuel slurry directly into the flame of the cement kiln. The grinding of the solid hazardous waste material in the milling apparatus prior to its introduction into the kiln provides for a rapid and instantaneous ignition of the solid hazardous waste materials thereby not adversely affecting the forming clinker or the operating parameters of the kiln.

摘要： An integrated method of removing alkali metal compounds from sulfur-bearing coal is disclosed. The coal is comminuted (4) and mixed (10) with water (8) to form a slurry (12). In the preferred embodiment, the slurry (12) is comingled with an SO.sub.2 -bearing gas (16) in a transport pipeline (52) to form an acidic slurry which dissolves the alkali compounds out of the coal. The slurry is then separated (22) into a solid portion (24) and a liquid portion (26), the solid portion (24) being combusted (34) to form the SO.sub.2 -bearing gas (16).

摘要： A continuous process for the combustion of solid fuels in a fluidized bed of solid particles under conditions such that flue gas is essentially free of dust and oxides of sulfur and nitrogen. Fuel is charged as an aqueous slurry and additional water condensed from the flue gas is recycled to the combustion zone. Combustion is promoted both by water vapor and alkali added with fuel slurry, while the alkali serves also to neutralize and remove sulfur in completely oxidized, or sulfate, form. Useful heat is recovered from the hot gases leaving the combustion zone and, in some cases, from the fluidized bed itself. Under the pressure of the system recovery of heat results in condensation of water which serves to scrub dust from the flue gas, slurry product ash and furnish recycle water, which controls reaction temperature as well as promoting the combustion.
