Experimental Survey of Co-Combustion and Gasification of Biomass Furnace

Abstract

When researching, designing and manufacturing a model of Co-combustion and gasification of biomass furnace with the goal of achieving the amount of air supplied for the combustion process, here the first stage is combustion/burning process, so there is excess oxygen, which means excess air  > 1.The next stage is gasification, i.e. anaerobic combustion, so the oxygen content of the combustion process is anoxic, which means that the excess air is  < 1. It is the combination of such simultaneous combustion and gasification that the energy conversion process will achieve higher thermal efficiency. In this report, we present a summary of experimental research results on the "model" of the furnace and simultaneous gasification, the results of evaluating the quality of the gas generated from the combustion process, the achieved flame temperature inside the furnace, the heat capacity of the furnace and the selection of the air flow provided for the combustion process. With the type of furnace and gasifier at the same time in this research, it can be used for drying agricultural products of household scale, or group of households, or used for medium scale at agricultural product processing establishments/enterprises and suitable for rural and/or mountainous conditions in Vietnam.
