Acoustic cleaning assembly for use in power generation systems and method of assembling same

A power generation system comprising:

• a combustion assembly for generating combustion gases;
• a particulate filter assembly coupled to said combustion assembly for removing particulate from the combustion gases;
• and
• at least one acoustic cleaning assembly coupled to said particulate filter assembly to facilitate removing debris from said particulate filter assembly, said acoustic cleaning assembly comprising:
• a horn assembly;
• a generator body coupled to said horn assembly, said generator body comprising an inner surface that at least partially defines an outlet plenum, and an opening that extends in flow communication between said horn assembly and said outlet plenum;
• an end cap coupled to said generator body and comprising an inner surface that at least partially defines an inlet plenum;
• and
• a diaphragm coupled between said generator body and said end cap, said diaphragm channels air from said inlet plenum to said outlet plenum to facilitate generating sound waves within said outlet plenum.

A method of assembling an acoustic cleaning assembly, said method comprising:

• providing a horn assembly;
• coupling a generator body to the horn assembly, the generator body including an inner surface that at least partially defines an outlet plenum, and an outlet opening that extends in flow communication between the horn assembly and the outlet plenum;
• coupling an end cap to the generator body, the end cap including an inner surface that at least partially defines an inlet plenum;
• and
• coupling a diaphragm between the generator body and the end cap, the diaphragm including an upstream surface and an opposite downstream surface, the diaphragm oriented to enable a flow of air to be channeled from the inlet plenum to the outlet plenum to facilitate generating sound waves within the outlet plenum.
