Stirling Cycle Engine for Combustion Heat Biomass

Abstract

A Stirling engine which has a number of merits such as a wide choice of various fuels, clean exhaust, small noise, low vibration, etc. has been studied. The aim of this study is the development of farm usable Stirling engines which are simple and free from maintenance.
The trial-made Stirling engine driven by combustion heat of biomass was a single acting displaces type and had a power piston and a displacer piston as two separate cyliner systems connected by a crank mechanism. The heat generated by a gasifier combustor which could burn woody biomass pellet fuel of bark strip chips was used to operate the engine. The engine was tested and its perforomance was investigated for factors influencing output power.
