Abstract

Charcoal production of 2-3 years old Leucaena leucocephala by rice-husk, saw-dust and earth mounds at thickness of covering matters from 7.5 to 22.5 cm, results means of charcoal yield and properties from 27 tests as follows; charcoal yield 30.8%, charcoal density 0.33 g/cc, heat of combustion 7,651 cal/ g, volatile matter content 15.3%, fixed carbon content 82.3%, ash content 2.4%, time required to boil 14 min, and heat utilization 33.9%. Analysis of variances of the means confirm that both types and thickness of coververing matters do not affect charcoal yield and properties at 95% confidence interval.
