Waste to energy plants face particular problems both in material handling and in the nature of ash that can deposit on heat exchange surfaces. Burning municipal waste or bio-fuels can lead to very sticky ash deposits which cause drop offs in plant efficiency and shutdowns.

By installing Acoustic Cleaners in boilers high thermal efficiencies can be maintained for longer. Fuel feed stocks and combustion products can be very changeable in nature making plant design difficult acoustic cleaners can be used within ductwork, silos and hoppers to maintain material flow.
