Combustion Augmentation of Poorly Combustible Materials with High Water Contents

Abstract

This study was undertaken as part of an effort for effective treament of wastes and utilization of their energy. It is an application of the spectacular advantages of porous media to energy conversion and transport, which has already been successfully applied to the combustion augmentation of extremely low calorific gases and solid poor combustibles with high ash contents. The combustion characteristics of combustibles with high water contents have been discussed extensively and also examined by subsequent experiments. Mixtures of wheat flour and water were used as the test fuels. Experimental results show that the unaided combustion of fuels with up to 65% water content has been realized in these experiments ; the apparent heating value of which was 3.51 MJ/kg(839 kcal/kg).
