An experimental study of waste surrogate (sulfur hexafluoride) destruction in a low speed dump combustor is described. The lengths of the combuslor cavity and plenum can be adjusted as a means of exciting combustion instabilities which can produce certain types of acoustic modes. In cases where the surrogate is injected either into recirculation zones within the combustor cavity or into the plenum, very high destruction and removal efficiencies (> 99.999%) can be obtained, particularly at relatively high heat release rates. Combustion instabilities are observed to play a role in the degree to which waste is destroyed, and are correlated with various acoustic modes. Under certain conditions, particularly where waste is injected into the plenum along with auxiliary fuel and oxidizer, acoustic behavior may provide a useful real-time indicator of proper incineration conditions.
