    Abstract: The present invention provides a method of operating a solid fuel fired boiler comprising introducing a solid fuel and an iron-bearing material into the boiler. The solid fuel is at least partially combusted in the boiler to produce an ash slag, wherein the ash fusion temperature characteristics (i.e., one or more of the IDT, ST, HT and FT) of the ash slag are different than the ash fusion temperature characteristics of the ash slag that would result on combustion of the solid fuel alone. The method of the present invention is particularly applicable to slag tap boilers, including cyclone-type boilers. These boilers are, typically, designed to operate with a liquid ash slag.

    Abstract: In a vertical roller mill in which a fixed-type cyclone sorter is provided in a casing, the fixed-type cyclone sorter includes a conical member; a fixed-blade entrance window through which a solid-gas two-phase flow is introduced into the interior of the conical member; a flat plate-like fixed blade that causes the solid-gas two-phase flow to spiral; an inner cylinder into which pulverized coal is guided from the bottom end thereof toward the top end thereof by means of spiraling of the solid-gas two-phase flow; and a pulverized-coal exit through which the pulverized coal guided to the top end of the inner cylinder is guided outside the conical member, wherein the fixed blade is provided with a tip portion where a downward flow is increased for the solid-gas two-phase flow guided into the interior of the conical member from the fixed-blade entrance window.

    Abstract: A continuous fluidized-bed combustion process for particulate carbonaceous feedstock of high ash content. The feedstock fuel is prepared from culm or mine tailings washed in a dense media and crushed to yield a fuel product having an ash content in a range of about 30 percent to about 50 percent, by weight. The feedstock fuel is mixed with fine particles of scavenging material, such as limestone or dolomite, and the resulting feedstock mixture is burned in a circulating fluidized-bed combustion chamber. A portion of the ash remaining after combustion is discharged out the bottom chamber, the remainder being carried with the combustion gases through a hot cyclone and heat exchangers for generating power. The ash within these gases is separated and recirculated through the fluidized bed, and the combustion gases are discharged.

    Abstract: The apparatus operates to supply the air requirements for grinding a fuel material to the mill to guarantee the correct particle size and to decouple from the air emitted from the grinding apparatus a certain proportion so the combustion of the ground fuel material will be conducted at a ratio of less than the usual 3 to 1 ratio of air-to-fuel so the combustion can be controlled to reduce the nitrous oxide emission, the air that is decoupled is returned to the grinding apparatus with a supply of make up air that is heated for purposes of drying the material in the grinding apparatus.
