Abstract

This bulletin describes work carried out by the Process and Storage Engineering Department of the Natural Resources Institute on the conveyance of particulate biomass materials by means of low pressure air injectors for applications in small-scale to medium-scale combustion systems. Experimental data on the injector entrainment ratios for particulate-laden gases are compared with values calculated from theory. Procedures are given for an injector design optimized for minimum fan-power and fan-pressure requirements. lt is concluded that the theoretical procedures developed for injector design and performance prediction for clean gases can also be applied, with simple modifications, to the dilute-phase entrainment of particulate materials in the injectors. This publication is primarily intended for use by engineers in the design of injector systems for application in small-scale to medium-scale particulate biomass combustion systems.
