    Abstract: Mineral additives and a method for operating a waste-to-energy furnace are provided in order to improve its operational performance and availability, increase the lifetime of the combustor building materials (refractory walls and heat-exchanger metallic tubes) and flue gas treatment equipment, improve ash quality, reduce emissions and avoid combustion problems such as agglomeration, slagging, deposition and corrosion. A method for operating a waste-to-energy furnace, such as a fluidized bed reactor, pulverized-fuel combustor, grate combustor includes introducing mineral additive into the furnace. The method further includes heating at least a portion of the mineral additive either intimately in contact with the fuel, such that the ability of mineral additive to induce crystallization of the surface of forming ashes is enhanced, or minimizing the contact of the mineral additive with the fuel and the forming ashes, such that the solid-gas reactions between the mineral additive and the volatile compounds in the flue gas are favored and the mineral additive power to capture at least a portion of the inorganic volatile compounds present in the furnace is enhanced.

    Abstract: A method and apparatus for reducing NOx emissions from the combustion of carbonaceous fuels using three stages of oxidation and second stage in-situ furnace flue gas recirculation. In the first stage, a partial oxidation combustor is used to partially combust the fuel in the presence of heated combustion air. The fuel gas produced in the partial oxidation process is passed to a second stage partial oxidation combustor while molten slag is removed and disposed of. A second preheated combustion air is introduced into the second stage combustor to produce a reducing flue gas and is injected into the furnace in such a way as to create the desired in-situ furnace flue gas recirculation. A third combustion air is mixed with the flue gas in a third stage of combustion to substantially complete the combustion process. Preheated steam may be added to the first or second stages of combustion.

    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: Verfahren zur Reduzierung des Schadstoffpotentials in Abgasen und Rückständen von Verbrennungsanlagen. Die Aufgabe liegt darin, ein Verfahren zur Reduzierung der Korrosionsneigung und Schadstoffbildung von Abgasen in Verbrennungsanlagen bei einer Verbrennung von festen Brennstoffen mit stark variierender Chlorbeladung vorzuschlagen, das mit einer Abgasreinigung mit geringeren Überschuss an Neutralisationsmittel auskommt und die Qualität der Verbrennungsrückstände verbessert. Die Aufgabe wird dadurch gelöst, dass bei einer Verbrennung eines ersten Brennstoffstroms (6, 10) mit wechselnder Beladung an einem Schadstoffausgangsstoff zusätzlich mindestens ein zweiter Brennstoffstrom (6, 7) mit einer gleich bleibenden Beladung des Schadstoffausgangsstoff in die Verbrennung zugeführt wird, wobei ein Brennstoffgemisch mit einer konstanten Beladung an dem Schadstoffausgangsstoff entsteht.
