Abstract
ABSTRACT
The ability to carry out extractive sampling in the high temperature zones of the USEPA Combustion Research Facility (CRF) pilot scale incinerator makes it mandatory that it also be possible to measure combustion gas flow at these sites. Helium dilution measurements have shown great promise for this application. In addition, such methods have been shown to be adaptable to the direct measurement of residence time and the distribution of residence times (RTD) in the secondary chamber. Typical results of residence times and RTD for the CRF rotary kiln and afterburner system are presented.
