    Abstract: A process is provided for burning a coal water slurry comprising providing clean coal fines of less than 100 mesh at about 50 weight % and water at about 50 weight % by co-firing the coal water slurry in a continuous stream with a separate stream of pulverized coal wherein about 80% of the total BTU output of the furnace is provided from the pulverized coal and approximately 20% of the BTU output is provided from the coal water slurry. First, a quarl in the furnace is preheated using natural gas, for example. The furnace is next fired with a fuel source of 60% pulverized coal and 40% natural gas. A coal water slurry with fines of minus 100 or smaller is subsequently gradually introduced into the furnace as the gas input is gradually decreased.

    Abstract: A slurry of liquified gas such as carbon dioxide and finely pulverized coal particles is provided in a mixing chamber and discharged from the chamber into a pipeline for conveyance to a power plant. During discharge from the mixing chamber pressurized gas at a sufficiently high pressure is injected above the slurry mix to maintain adequate pressure during discharge and prevent cavitation at the inlet port of pumping means employed in the pipeline. The slurry is depressurized at the downstream end of the pipeline by movement through pressure reduction means so that it is decompressed non-adiabatically and the coal and gas particles are separated. The gas remains at a low temperature and is passed in heat exchange relationship with cooling water from the power plant cooling tower to lower the temperature of same and consequently increase the efficiency of the power plant. In another embodiment the gas comprises carbon dioxide and a portion of the cool carbon dioxide is discharged directly into the basin of the cooling tower to reduce the water temperature and provide beneficial cooling water chemistry control.

    Abstract: A continuous process for the combustion of solid fuels under conditions such that flue gas is essentially free of particulates and oxides of sulfur and nitrogen. Fuel is charged as an aqueous slurry and additional water condensed from the flue gas may be recycled to the pressurized combustion zone. Combustion is promoted both by water vapor and alkali added with the fuel slurry, while the alkali serves also to neutralize and remove sulfur in completely oxidized, or sulfate, form. Heat of combustion raises the temperature of the reactants above the critical temperature of water, forming a hot fluid from which useful heat is transferred. Under the pressure of the system, heat recovery results in condensation of water, retaining and slurry product ash and providing recycle water, which helps to control reaction temperature as well as to promote the combustion.

    Abstract: A fuel producing system for a solid/liquid mixture. The system comprises a mixing reservoir having a first inlet for receiving a combustible liquid fuel, and a second inlet for receiving a solid fuel pulverized to a mixable state with said liquid fuel. Mixing means is provided in the mixing reservoir to mix both fuels. Quantitative control means is also provided in the reservoir to measure predetermined amounts of the liquid and solid fuels delivered therein. A holding reservoir receives the solid/liquid fuel mixture from an output conduit of the mixing reservoir. Pump means is provided in the output conduit. First control means is further provided to shut off the flow of the fuel mixture to the holding reservoir to permit the mixing of further fuel mixture in the mixing reservoir. A second control means initiates the flow of the fuel mixture to the holding tank when the mixture fluid therein is extracted to a predetermined low level.
