Combustion of low heating value fuels and wastes in the spouted bed

Abstract

Abstract In a spouted bed burner, the flow‐maintained vortex of particles operates as a heat exchanger, preheating the incoming mixture without diluting it. This makes it a combustor especially attractive for incinerating low heating value fuels and wastes. Bench‐scale experimental studies were carried out to assess the ability of the spouted bed to burn efficiently poor fuels and waste materials in various aggregative states. The paper reports results of two series of experiments with gaseous and liquid fuel‐containing streams. High levels of hydrocarbon conversion and combustion efficiency were attained for mixtures that would not be combustible by other methods without an auxiliary fuel.
