A method and a facility for producing electricity, wherein the following steps are performed: a) supplying a solid recovered fuel, b) producing a raw synthesis gas from the solid recovered fuel, c) purifying the raw synthesis gas in order to generate a synthesis gas in which the reduced concentration of tars determines a dew point of the tars less than or equal to 20 C., d) cleaning the synthesis gas purified in this way in order to obtain a clean synthetic gas, e) lowering the relative humidity of the clean synthesis gas, and f) injecting at least a portion thereof into a gas engine in order to produce electricity.

A system for beneficiating landfilled or ponded waste coal fly ash makes use of a carbon reduction kiln comprising multiple independent heat zones so that the waste coal fly ash is preferably exposed to indirect heat when received in such zones. The system may include a carbon capture system operatively connected to the carbon reduction kiln.

A ponded ash beneficiation system and related methods treat either landfilled or ponded waste coal fly ash by removing at least 75% of the carbon from a collected quantity of such waste coal fly ash. Analysis and testing of the collected waste coal fly ash to determine optimal air balance, indirect heat temperature and retention time. Subjecting a stream of such waste coal fly ash to temperatures ranging from 900? F. and 1150? F. along with air addition calibrated as a function of the LOI of the carbon in such waste coal fly ash. This stream is exposed to the foregoing range of temperatures and corresponding air addition for a range of time between 20 minutes and 90 minutes, in certain aspects of the disclosure.

A method for efficiently conveying impurities in a pressurized fluidized incinerator system is provided. Cleaning gas is supplied to an upper valve, and thereafter, the upper valve is driven so as to communicate an upper discharge device and a tank. The upper discharge device is driven so as to convey the impurities from the dust collector to the tank, and thereafter, the upper discharge device is stopped and the upper valve is driven so as not to communicate the upper discharge device and the tank. Thereafter, the supply of the cleaning gas to the upper valve is stopped.

[Object] To perform a magnetic decomposition treatment by effectively utilizing smoke emissions.

[Solution Means] When an opening 112 is opened and hot air is blown by a hot air gun 40, the waste is thermally decomposed inside the thermal decomposition treatment chamber 110. When smoke emissions generated by the thermal decomposition pass through a shower 210 and a swashplate filter 220 of the filter section 200, a temperature thereof is lowered and tar is removed, and then the smoke emissions pass: through a blower 230, and when the smoke emissions pass through a water tank filter 240, tar is further removed, and moisture is removed by a cloth filter 250. Thereafter, odor is eliminated by a zeolite filter 260 and an activated carbon filter 270, and then, from an intake duct 30, and the smoke emissions are fed to the thermal decomposition treatment chamber 110.

No new matter was added in the amendment.

A combustion ash handling method of handling combustion ash discharged from a combustion furnace that combusts a petroleum-based fuel includes: separating the combustion ash into a heavy component and a light component by a dry-type separation technique; feeding the light component to the combustion furnace as a fuel; and recovering the heavy component. A metal such as vanadium is separated and extracted from the heavy component of the combustion ash.

The objective of the present invention is to provide a method for preparing cremation crystals, the method using phosphoric acid extracted from cremated remains as a catalyst in the heat treatment of ashes so that transparent cremation crystals can be prepared only with components of skeletal remains derived from a single individual, and using only skeletal remains of a single individual through the control of the classification ratio of raw bone powder and phosphorus-extracted bone powder, and the like, so that the amount of phosphorus in the crystals is controlled, thereby enabling cremation crystals transparency to be controlled, and thus aesthetic requirements of consumers are satisfied and use as various kinds of jewelry is also facilitated.

A volatilization vessel, such as a carbon reduction kiln, comprises a processing environment and associated apparatus and an air-input component configured to maintain a negative pressure and an oxygen-rich atmosphere during a time period of elevated temperature, so as to produce a beneficiated coal fly ash having 2% or less LOI from landfilled or ponded waste coal fly ash. The waste coal fly ash is preferably exposed to indirect heat when received in such zones. The system may include a carbon capture system operatively connected to the carbon reduction kiln.

Systems and methods for beneficiating a recovered fly ash material and/or recovering fly ash from an impound site are described. The method may include thermally treating a first portion of a recovered fly ash material to form a thermally treated fly ash having a first temperature of at least 1000 F., and contacting the thermally treated fly ash with a second portion of the recovered fly ash material to cool the thermally treated fly ash to a second temperature of less than or equal to 500 F. and form a fly ash product. The fly ash product may have a carbon content less than 8% by weight, based on the total dry weight of the fly ash product.
