The objective of this study was to study the effect of wall temperature, preheated air temperature and dimension on combustion characteristics of bio-pellets from Cocoa Pod Husk (CPH). CPH was sun-dried, crushed and screened to obtain the particle size of less than 1 mm. Five grams mixture of CPH and binder with the composition of 70 and 30% weight, respectively was palletized and dried at 50°C for 5 h. The result shows that wall temperature and preheated air temperature significantly affected the mass losses of CPH. Temperature had obviously been a main driver for combustion process. Meanwhile, the wider surface area will apparently provide faster mass loss of the pellet. In contrast to the mass loss, CO emission factor was not significantly affected by wall temperature and preheated air temperature while the higher the ratio of surface area to pellet mass, the lower the CO emission factor. The study has identified that CPH had similar combustion characteristic compared with other biomass so that it is very potential as an alternative fuel for combustion system.
