| Abstract | This paper presents the experimental study of the combustion in a cyclone combustor. The combustion chamber is a cylindrical shape 1.4 m in diameter and 2.8 m in height. The height of bed in chamber is designed to be adjustable at four levels: 30, 45, 50 and 60 cm as desired with a set of air nozzles placing circumferentially on the chamber to produce air-swirl flow inside. The equivalence ratio ( ) was set to be 0.8. The feed rate of rice husk was held constant at 0.04 kg/s. Experimental results show that the emission of exhaust gas from stack is composed of O2=18%, CO=1,651 ppm, SOX=8 ppm and NOX= 49 ppm at 50 cm bed-height. The maximum thermal efficiency is 85%. |
