It is well known that the performance and the safety may be hindered because of the clinker formation, when high
ash content biomass solid fuel is applied to small scale combustion appliances. In this study, the ultimate goal is
to suppress clinker formation of biomass solid fuel. It gives the suggestion that is very important to development
and the improvement of the combustion apparatus to arrange clinker formation mechanism of the biomass solid
fuel. In this study, new solid biomass fuels, Bio-coke, that can be applied to small scale combustion appliances are
manufactured and the clinker formation situation is compared through mixed firing experiments with ordinary
pellets. Furthermore, important knowledge considered to help development and the improvement of the combustion
apparatus was provided.
Bio-coke that does not cause melting of combustion ash after combustion is also important from the viewpoint of
promoting effective utilization of biomass combustion ash. However, a technology for mass-producing bio-coke that
can be used in a household compact combustor has not yet been established. As a result of working on improvement
of batch type manufacturing process using six-hole molder system for the purpose of improving production capacity
of small diameter bio-coke, the following results were obtained. (1) It was found that it is possible to increase the
size per unit by 85% by optimizing the initial moisture content. (2) It was found that by shifting the molding process
using two molding units, the manufacturing capacity per unit time can be improved by about 50-90%.
Atsuhiro Kawamura recieved a doctorate in field of Bio-application and System Engineering from Tokyo University of Agriculture and Technology in 2006, based on the achievement in the industrial world for 20 years.
