Abstract
The generation of clinker ash from exhaust gas dust in a boiler, furnace or the like which employs dust coal as a fuel can be controlled with excellent results by adding to a fuel at least one iron compound in a relatively small amount, and, preferably, at least one compound of a metal selected from the group consisting of Cu, Mn, Co, Ni and Cr, and, preferably, at least one compound of a metal selected from the group consisting of an alkali metal and an alkaline earth metal, in the form of an aqueous solution or a water slurry in which the particles are capable of passing through a 100-mesh screen.
Claims8
A method of controlling the generation of clinker ash from exhaust gas dust comprising controlling the formation of clinker ash in a boiler or furnace which employs dust coal as a fuel by adding to a fuel at least one water soluble iron compound in an amount of 2 to 200 ppm in terms of Fe.sub.2 O.sub.3 on the basis of the amount of dust coal, said iron compound(s) being in the form of an aqueous solution.
A method of controlling the generation of clinker ash from exhaust gas dust comprising controlling the formation of clinker ash in a boiler or furnace which employs dust coal as a fuel by adding to a fuel at a mill installed in a fuel line at least one water soluble iron compound in an amount of 2 to 200 ppm in terms of Fe.sub.2 O.sub.3 on the basis of the amount of dust coal, said iron compound(s) being in the form of an aqueous solution.
