Stirling Engine with Flax® Burner Fuelled with Fast Pyrolysis Liquid

Abstract

Fast pyrolysis liquid was combusted with a modified propane gas FLOX® burner (WS) mounted to a Stirling CHP unit (SOLO 25 kWth). The propane burner was modified by an air pressure atomiser designed for pyrolysis liquids. Nearly 110 hours of operation with different fuel loads have been achieved, engine performance and emissions were recorded. The Stirling tests proved that pyrolysis liquids can be burned efficiently and with low emissions in a FLOX® mode operating burner attached to a Stirling CHP unit.
