ABSTRACT:
A system for automatically admitting and regulating the flow-rate of an alkaline substance admitted to the combustion chamber (10) of a refuse incineration plant for the hot destruction of the acids contained in the combustion fumes, comprising sensors (22, 23, 24, 25, 51, 124, 140) for detecting the concentration of the acids in the fumes in the combustion chamber (10) and working conditions of the plant such as temperature, flow-rate and humidity of the fumes, and processing means (26, 27) connected to the sensors for identifying, in dependence on the concentration of acids and of the working conditions, a flow-rate of an alkaline substance to be admitted to the combustion chamber in order to achieve a destruction yield which reduces the concentration of acids in the fumes discharged from the plant to a predetermined value, and for operating flow-rate regulation members (40) for admitting to the combustion chamber the flow-rate of an alkaline substance thus identified.
