Claim:
1. A debris removal system for a turbo-machine, the turbo-machine comprising a compressor section, a combustor assembly, and a turbine section, the debris removal system comprising: a casing at least partially defining a flow path for a working fluid through or around one or more of the compressor section, the combustor assembly, and the turbine section of the turbo-machine, the casing defining an inner surface in contact with the working fluid, the inner surface defining a plurality of debris routing channels, wherein the plurality of debris routing channels are disposed on the inner surface; and a debris collection mechanism downstream of the plurality of debris routing channels, the plurality of debris routing channels extending generally towards the debris collection mechanism, such that the plurality of debris routing channels route debris towards the debris collection mechanism during operation of the turbo-machine; wherein the debris collection mechanism is a debris trap attached to or made integrally with the casing, the debris trap comprising a lip positioned at least partially in the flow path and defining a gap configured to receive debris from the plurality of debris routing channels, the gap defined directly between the lip of the debris trap and the inner surface of the casing; wherein the debris trap further comprises a cavity in fluid communication with the gap for receipt and storage of the debris, the cavity located on an outer surface of the casing and upstream of the lip relative to the flow path for the working fluid.
