Abstract
A process for controlling both fireside ash deposits and corrosion, and fouling, corrosion, and emissions due to SOformation within a fossil-fuel-fired combustion system, such as a furnace forming part of an electrical power generating plant. A solution of a soluble magnesium compound, which can be derived from wastes, such as the bleed stream from the power plant's SOscrubber, is injected into the combustion products within the furnace in the form of a fine spray and at a point at which the temperature is sufficiently high to produce submicron-size MgO particles. The SOreacts with the MgO particles to form MgSO. Insoluble magnesium compounds can be added to the solution to produce larger (micron sized) MgO particles on thermal decomposition. The micron-sized MgO particles are deposited on furnace surfaces to reduce ash deposits and to reduce catalytic generation of SO. The boiler wastes can be reacted with other industrial process waste products to provide marketable chemicals.
