METHOD FOR UTILIZING PHOSPHOROUS-CONTAINING WASTES

摘要

The invention relates to a method for utilizing phosphorous-containing wastes in facilities for the exclusive energy recovery of said wastes, such as mono-incinerators for sewage sludge and/or animal meal, during the co-incineration in power plants or during additional firings in cement industry furnaces or comparable furnaces of other branches of industry, in which method an installation for melt gasification of P-containing substances is integrated into existing or new facilities of said kind. Depending on the composition of the P-containing substance, said installation generates a metal melt, a lime-silico-phosphate-containing slag low in heavy metals, and a fuel gas, and the fuel gas is supplied as fuel to the facilities for the exclusive energy recovery.
