A filter for use in a baghouse. The filter is to be supported by a tubesheet that separates dirty fluid and clean fluid chambers of the baghouse. The filter including a filtration bag that has an open end adjacent to the tubesheet and an encircling sidewall that extends from the open end to a distal end along a direction of a central axis of the filtration bag. The bag sidewall permits passage of fluid there through so that the fluid may pass from the dirty fluid chamber to the clean fluid chamber and blocks passage of at least some particulate material against proceeding to the clean fluid chamber. The filter includes a cage located within the filtration bag. The cage has structure to permit expansion of the cage to increase a cage diameter that forces the bag sidewall taut against the cage.

An acoustic cleaning system includes an operating device having an interior portion. An acoustic cleaning device provides for the passage of a sound wave into the interior portion of the operating device. The acoustic cleaning device includes a horn section attached to an elongated section having a linear or non-linear shape. Sound waves are configured to pass from the elongated section to the horn section and into the interior portion of the operating device. The elongated section is removable from the horn section such that the elongated section is interchangeable with an elongated section having a different length, such that the sound waves are configured to have a frequency between 55 Hz to 75 Hz depending on a temperature of the operating device.

An acoustic cleaning assembly that includes a horn assembly and a generator body that is coupled to the horn assembly. The generator body includes an inner surface that at least partially defines an outlet plenum, and an opening that extends in flow communication between the horn assembly and the outlet plenum. An end cap is coupled to the generator body and includes an inner surface that at least partially defines an inlet plenum. A diaphragm is coupled between the generator body and the end cap. The diaphragm channels air from the inlet plenum to the outlet plenum to facilitate generating sound waves within the outlet plenum.

A system includes an emissions control system. The emissions control system includes a chemical injection conduit. The emissions control system also includes a chemical injector coupled to the chemical injection conduit, wherein the chemical injector is configured to output an emissions control chemical into the chemical injection conduit. The emissions control system further includes a wave generator coupled to the chemical injection conduit, wherein the wave generator is configured to output multiple waves that propagate through the chemical injection conduit into a flow path of combustion products to drive improved mixing of the emissions control chemical with the combustion products.

The present application provides a pulsed detonation cleaning system for cleaning an enclosed structure. The pulsed detonation cleaning system may include a pulsed detonation combustor cleaner and an external fuel-air flow. The pulsed detonation combustor cleaner delivers the external fuel-air flow into the enclosed structure and ignites the external fuel-air flow to clean the enclosed structure.
