Mr. Golriz et B. Sunden, A METHOD FOR TEMPERATURE-MEASUREMENTS IN CIRCULATING FLUIDIZED-BED COMBUSTORS, Experimental thermal and fluid science, 9(3), 1994, pp. 274-282
A method for measuring the local suspension temperature with a shielde
d thermocouple in the combustion chamber of a circulating fluidized be
d (CFB) boiler is described. The report also includes an estimation of
the error in the local temperature measurement due to radiation losse
s and some test results in the 12 MW(th) circulating fluidized bed boi
ler at Chalmers University of Technology, Goteborg, Sweden. A typical
suspension temperature distribution in the combustion chamber of the C
FB boiler is provided, and the estimated uncertainty is found to be be
low 4%, corresponding to 25-degrees-C at normal operating condition. T
he experimental results are compared with available data in the litera
ture.
