Combustion quality evaluation of biomass coke in shaft-type gasification and melting furnace

Abstract

In order to apply biomass coke to the shaft-type gasification and melting furnace, we investigated combustion quality using a combustion test apparatus that simulates the bottom of the furnace. As a result, we found that biomass coke consumes carbon at a high rate and absorbs heat due to solution loss reaction. There is a strong correlation between the geometric specific surface area of coke and the carbon consumption rate. It is thought that the difference in biomass coke raw materials and manufacturing processes has a relatively small effect on the consumption rate. In order to secure the same amount of heat as coal coke, it is necessary to reduce the geometric specific surface area and suppress the carbon consumption rate.
