Abstract
This work presents a study for biomass possible to bring renewable energy in a swirling fluidized bed combustor (SFBC). The main objective of this experimental work was to study the biomass component and excess air of biomass. Palmyra palm shell, Leucaena (lam.), and water hyacinth are using as fuel in the tests. Quartz sand of 600-850 µm and static bed height of 20 cm was used as inert bed material. For all of the tests, the feed rate was fixed as 45 kg h-1 for variable excess air (of 40%, 60% and 80%). As the experimental results, the temperature profiles in SFBC were obviously seen deviate when tests with higher excess air. In the test run, the highest cellulose (palmyra palm shell) for 80% excess air had CO and NO emissions were found in quite stable level (less than 250 and 300 ppm, respectively). The combustion efficiency more than 99% could be achieved in this work.
