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 automatically sorting and blending coal and other fuel stocks through a computer-controlled process in order to achieve a specified blend of materials. By sorting fuel stocks with different characteristics into different stacking points, an operator can then automatically combine and uniformly blend these sorted fuel stocks to create a variety of blended materials with different properties tailored to the specific needs of the operator or end user. The computer-controlled nature of the process allows for precise blending in an automated and more efficient and reproducible fashion.

Abstract: With the system of the present invention, high sulfur content coalnulla mixture of coal, sulfur compounds and ash (e.g., stone and slate)nullis crushed, and a proportion of the higher density sulfur compounds and ash are separated from the lower density coal. The result of the separation process, the continuous supply of the separated coal mixture, is then continuously monitored for sulfur content. The system uses electronic controls to vary the proportion of sulfur compounds and ash which are separated out and removed from the coal mixture so as to maximize the economics of reducing the sulfur content, and of generating power. A centrifugal separator is used for continuously separating the relatively dense high sulfur content coal and ash from the coal mixture. This separator preferably has a substantially rotationally symmetric drum element which rotates about a horizontal central axis. The proportion of sulfur compounds and ash which are removed is controllable by controlling the particle size of the crushed coal mixture, controlling the speed of the separator and controlling the separator openings which allows the high-density material to emerge.
