Abstract:
This research was aimed to study the effect of biomass size on emission and
combustion efficiency in swirling fluidized-bed combustor (SFBC). Coconut shell was
shredded and sized into three sizes (df =0.5, 2.5 and 5.0 mm) for using as fuel in the tests.
Quartz sand of 600850 μm and static bed height of 20 cm was used as inert bed material.
For all of the tests, the feed rate was fixed at 45 kg/hr for variable excess air (of 40, 60, 80
and 100%), using an annular spiral air distributor as the swirl generator. Axial temperature,
CO and NO concentrations inside the combustor and the emission at cyclone outlet were
investigated. As the experimental results, the temperature profiles in SFBC were obviously
seen deviate when tested with higher excess air. In all tests run, CO and NO emissions were
found in quite stable level (less than 220 and 100 ppm, respectively). Increasing the coconut
shell size found reduction of CO emission; meanwhile, NO emission was constant but
significantly decreased with lower excess air. The combustion efficiency more than 99%
could be achieved in this work.
