Abstract

This paper reports the experimental work carried out to determine the cold flow behavior of a swirling fluidized bed incinerator (SFBI) with Quartz sand as bed particles. Three different sizes of sand particles were studied: 425-600µm, 600-850µmand 850-1180µm for four bed heights: 25 mm, 30 mm, 35 mm and 40 mm. The density of the particles was 2450 kg/m3while the gas superficial velocity (Us) was limited to 3 m/s. It was found that the larger particles exceeded the swirl-able regime and only possessed bubbling regime during fluidization. It was also found that the bed pressure drop was higher for higher bed heights and increased when the bed operates in the swirling regime. The study concludes that bed with the smallest particle size (425-600µm) and highest bed height (40 mm) has the desired characteristics to be used in the SFBI.
