Abstract

The authors have proposed a horizontal rotary kiln with internal spiral transport mechanism as a biomass gasifier. In this rotary kiln, the gasification chamber and the combustion chamber are separated by the transport mechanism. And, solid particles move between two chambers through the transport mechanism. However, the gases in the chambers hardly mix because the transport mechanism is filled with solid particles, which act as gas seal. Thus, by applying to a gasifier, high/middle calorie synthesis gas is expected to be produced by using air without indirect heating. In the present study, a new two-layer type spiral transport mechanism was proposed, and the transfer rate of particle and gas sealability were examined by the cold model. As a result, it was clarified that the two-layer type spiral transport mechanism can transport particles faster in a state where a gas seal is formed as compared with the conventional spiral transport mechanism.
