    Abstract: A waste containing organic solids is fed into a boiler after it has been subjected to a hydrothermal reaction treatment in the presence of water. A slurry containing the waste is held under high-temperature and high-pressure conditions to cause a hydrothermal reaction such that an acidic slurry is formed during part of or throughout the process of the hydrothermal reaction. Thereby the content of oxygen in the waste relative to carbon atoms in building molecules of the waste is reduced. This concurrently causes removal of halogens in said building molecule and transferring the halogens into the slurry. The slurry then is cooled and dewatered and fed into a combustion section of the boiler. The waste slurry to be subjected to the hydrothermal reaction can be sorted into two portions for separate storage. One portion is a waste slurry the pH of which will increase as a result of the hydrothermal reaction. The other portion is a waste slurry the pH of which will decrease during the hydrothermal reaction. The two slurries are combined together and subjected to the hydrothermal reaction, with their relative amounts of supply being adjusted such as to form an acidic slurry either during part of or throughout the process of the hydrothermal reaction. Wastes can be supplied as a mass of high heat value into the boiler in such a manner that organic matter is transferred by a smaller amount into the aqueous phase during the hydrothermal reaction, and there is no scale deposit on the surfaces of those areas of the system components in contact with the liquid.

    Abstract: The present invention relates to a method of supplying coal and sulphur absorbent to a combustor with combustion in a fluidized bed. The coal is crushed and sorted into a fine and a coarse fraction. The fine fraction is mixed with water, possibly with oil and/or emulsifier, into a paste which is pumped into the bed of the combustor via a number of first nozzles. The coarse coal fraction is supplied to the combustor pneumatically in dry state, directly or via at least one lock hopper systems and a number of other nozzles. The invention also relates to a power plant for application of the method.

    Abstract: Methacoal Integrated Combined Cycle Power Plants comprise a thermal separation plant for producing condensate liquid fuel and particulate carbonaceous fuel from Methacoal fuels, coal-methanol suspensoids or slurries; gas turbine generator plants for burning the liquid fuel to produce electric power; steam turbine generator plants for producing electric power; a boiler plant for producing steam for steam turbines; a small firebox for burning reative particulate carbonaceous fuel, with minimum retention time for high temperature combustion gases and minimum oxygen required for combustion, thus minimizing emissions of nitrogen oxides and hazardous ultra-fine particulates; and means for controlling ash fusion and slagging problems. The two generating plants are respectively sized to provide the capacity required, and to consume the two fuels in the proportions produced from the Methacoal fuels, during normal operations, allowing fuel inventory control. Gas turbine exhaust gases provide most combustion air for burning particulate fuel. Other uses of gas turbine exhaust heat facilitate control and achieving the high overall efficiencies. Capacity is about one-fourth gas turbine generated power to three-fourths steam turbine generated power for these new plants. Conventional combined cycle power plants have about two-thirds gas turbine generated power and only one-third steam turbine generated power. The invention facilitates low-cost retrofitting of steam power plants. New power plants will be much less costly than other coal or lignite power plants available, including fluid bed combustion plants and integrated gasification combined cycle plants.

    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 a pump employed in the pipeline. The slurry is depressurized at the downstream end of the pipeline by movement through a pressure reducer 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.
