Abstract
The invention relates to a system for thermal combustion processes of matter such as, for instance, waste incineration. The system comprises a computer for measuring parameters of the combustion of the matter, wherein use, matter, such as for instance waste, is supplied to the system and combusted, thereby forming a flue gas. The system further comprises means for determining the concentration of CO2, O2 and H2O in the flue gas. The computer is arranged for determining, on the basis of the measured concentrations, the rate of combustion and/or the composition of the combustible part CHyOz of the waste supplied to the system, for the purpose of process control.
Claims12
A system for determining process parameters relating to thermal combustion processes of matter such as, for instance, waste in an incinerator, comprising sensor means and a computer coupled thereto for determining the parameters, wherein, in use, matter having a combustible part CHyOz is supplied to the incinerator and combusted, thereby forming a flue gas, characterized in that the sensor means are arranged for measuring the fractions XCO2, XO2 and XH2O in the flue gas and that the computer is arranged for determining, on the basis of the measured fractions, the composition (y/z) and/or the heat of combustion (HCHyOz, [J/kg]) of the combustible part CHyOz, with XO2, XH2O, XCO2 respectively representing the fractions of O2, H2O and CO2 in the flue gas.
