INVESTIGATION OF HEAT TRANSFER IN BED AND FREEBOARD OF FLUIDIZED BED COMBUSTORS
要約
Experimental results for heat transfer between immersed bundles of bare tubes and fluidized beds are reported. The experimental results are obtained on industrial boilers with a bed area from 2.5 to 4 m2 under conditions of long term operation. The bed temperature range has been 1073 °K−1233 °K, gas velocity between 1.8−4.5 m/s, mean particle size from 1.5 mm to 6.0 mm, freeboard furnace height of 2.3 and 5 m. The obtained data are compared with experimental results from literature.
