Abstract: An improved apparatus and process for removal of particulates entrained in a gas stream are provided. The removal process employs a pulse combustor to provide an acoustic pressure wave to acoustically enhance agglomeration of particulates which may be collected and removed using a conventional separation apparatus. The apparatus may be employed as a direct fired system for improved operation of gas-operated equipment such as a gas turbine, or may, alternatively, be employed as an add-on subsystem for combustion exhaust clean-up. Additionally, added particulates may include a sorbent for effecting sorption of other contaminants such as sulfur. Various other particulates for contaminant removal may also be introduced into the system as exemplified by alkali-gettering agents.

Abstract: An apparatus is provided for ensuring that a device--such as a gas turbine--that utilizes gases and will be damaged by particles in the gases greater than the predetermined size, will not be subjected to such particles. A filter, or the like removes particles from the gases, and is connected to the gas utilization device, with a particle concentrating device disposed between the particle remover and turbine. A particle detector is associated with the particle concentrator for detecting an undesirable level of particles above the predetermined size, and an alarm or other device is activated by the particle detecting means in response to an aberrant condition. The particle concentrator comprises a first conduit extending to a branch section, and branching to a second conduit and a third conduit. The second conduit, which may be blind, is a substantial continuation of the first conduit, while the third conduit makes an angle (e.g. about 90.degree.) with respect to the second conduit that is large enough that the vast majority of particles in the first conduit having a size greater than the predetermined size will flow into the second conduit, while gas and smaller particles will flow into the third conduit. The detector may be signal transmitter and receiver, an impact force sensing device, or a filter in the second conduit with a differential pressure sensor for sensing the pressure difference on opposite sides of the filter.
