    Abstract: A process for recovering the byproducts of a process that burns coal and for reusing the byproducts is disclosed. The process includes the steps of identifying a disposal site that contains the byproducts (typically flyash and bottom ash), removing at least a portion of the byproducts from the disposal site, analyzing a sample of the portion of the byproducts to determine the loss on ignition of the portion of the byproducts, introducing the portion of the byproducts along with pulverized coal into a pulverized coal furnace if the portion of byproducts have a loss on ignition greater than or equal to a predetermined loss on ignition value (typically greater than or equal to 1 to 5%), and burning the portion of the byproducts in the furnace with the pulverized coal to render the byproducts into a commercially valuable fly ash and bottom ash having very low loss on ignition, typically lower than 3%.

    Abstract: Bottom ash and flyash having high LOI is reburned in a pulverized coal furnace. The bottom ash is added to the coal supply before the coal is pulverized. Flyash is added to the pulverized coal stream for injection with the pulverized coal or is separately injected into the furnace at or slightly above the level of the coal burners in the furnace. The bottom ash and flyash is added to the coal in direct proportion of 1% to 3.5% of the coal.

    Abstract: The present invention relates to a means and method for at least injecting mitigant particles into the combustion region (fireball) of a biomass boiler. The mitigant particles mitigate the slagging, fouling and corrosion problems caused by biomass ash by at least capturing the biomass ash. The mitigant particles capture the biomass ash by forming a physical bond with the biomass ash such that it adheres to the surface of mitigant particles. By injecting the mitigant particles into the combustion region, the opportunity to capture biomass ash is optimised.

    Abstract: An object of the invention is to provide a method for controlling an NOx concentration in an exhaust gas in a combustion facility that uses a pulverized coal, which can easily control the NOx concentration in the exhaust gas to be discharged from a fuel facility that uses the pulverized coal as the fuel to or below a regulation value according to the Air Pollution Control Law and the like, and can also reduce an amount of a denitrifying agent or the like to be used, which is necessary for the control, by controlling the NOx concentration on the basis of the properties of the pulverized coal beforehand. The invention further includes: measuring a reaction velocity of each of chars corresponding to a plurality of types of pulverized coals beforehand; determining a relationship between the NOx concentration in the exhaust gas and the reaction velocity in advance; blending the plurality of the types of the pulverized coals so that the reaction velocity of the char becomes such a value as to correspond to a target NOx concentration or below, on the basis of the relationship; and supplying the blended pulverized coal to the combustion facility as the fuel of the combustion facility.
