Paper presented at the 5th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 1-4 July, 2007.
According to the European Waste Directive 2000/76/CE,
temperature of gaseous emissions in the postcombustion zone
of an incinerator is one of the key parameters that has to be
continuously measured and controlled. A bare thermocouple is
generally affected by different physical contributes which make
the gas temperature measurement incorrect.
This paper analyzes the errors that can arise when using a
bare thermocouple, describes principle design and uncertainty
of a suction pyrometer and a method to characterize a waste
incinerator. Results allow a correct thermal characterization of
the plant permitting a better energy management.
