Abstract
A system for cleaning the fouling and clogging of particulate matter associated with a fluidized gas bed. The system is particularly suited for use with Selective Catalytic Reduction reactors but its use is not limited thereto. The system includes a gas compressor to force cleaning gas through gas injection lines adjacent to retaining structures to be cleaned. The compressor produces sufficient pressure to cause the cleaning gas to dislodge the particulate from the retaining structures. A vacuum system withdraws the dislodged particulate and mixed gas from the reaction chamber.
