| Summary: | 碩士 === 國立臺灣大學 === 農業機械工程學系 === 81 === Recycling of the generating heat from biomass is an effective
handling process for the massive agricultural wastes . The
basic combustibility of agricultural wastes such as corn cobs
, rice hulls , stalks , and etc, were studied to facilitate
the design of an incinerator . In this research , corn cobs
which contains high volatile matter , low ash content and fast
combustion rate was found to be the most suitable material
for the fixed grate incinerator . As to the combustion of
rice husks which contain high ash content and slow combustion
rate , the movable gate and ash cleaning process were found
necessary . Due to the humid climate and highly utilization of
farm land in Taiwan , the agricultural wastes are usually
generated with high moisture contents. This study aims directly
at the influence of wet corn cobs upon the combustion
efficiency and tries , therefore , to solve the problem of
ignition . Also ,the inside temperature of incinerator was
predicted through an analytical model . The accuracy of
prediction was as high as 94 % after validation by
experiment . When the corn cob furnace is feeded with rice
hulls instead , the difficulty arised because of heavy falling
dust and congestion of the incomplete burning ash , which may
need further studies.
