Abstract
A method for analyzing or optimizing the operation of waste incinerator systems. The content of CO2 is measured in the exhaust gas and is used to determine the ratio of biogenic carbon to fossil carbon in the incinerated waste, if necessary after resetting to the CO2 reference quantity. The variability of the CO2 reference or the ratio of biogenic carbon to fossil carbon in the incinerated waste is determined and recorded according to quantity and duration. When optimizing the operation, the location of the waste in the bunker, from which the incinerated waste originates with a composition or variability that has now been ascertained using the method, is used to further remove or mix the waste.
Claims6
A method for analyzing operation of a garbage incineration plant, comprising the steps of:
- measuring an amount of CO2 in flue gas and optionally calculating a CO2reference by normalizing the measured amount to a constant oxygen content;
- determining a ratio of biogenic to fossil carbon in incinerated garbage using the measured amount of CO2 or the normalized quantity CO2reference;
- determining and recording a variability of CO2reference or of the ratio of biogenic to fossil carbon in the incinerated garbage by quantity and duration;
- and selecting garbage to be supplied to the incineration based on the determined and recorded variability of CO2reference or of the ratio of biogenic to fossil carbon in the incinerated garbage by quantity and duration.
