摘要： A high frequency pulsed fuel injector is disclosed. The fuel injector incorporates a resonance tube in outlet fluid communication with a fuel nozzle. During operation the resonance tube provides a pulsating output which is directed into the fuel nozzle. The pulsating output of the resonance tube perturbs the flow of fuel in the fuel nozzle, effectively breaking it up into discrete slugs or chunks for subsequent combustion in a combustion chamber. The combustion process is greatly enhanced by this breakup of the fuel jet, improving combustion efficiency as well as reducing undesirable emissions.
摘要翻译： 公开了一种高频脉冲燃料喷射器。 燃料喷射器包括与燃料喷嘴连通的出口流体中的共振管。 在操作期间，共振管提供被引导到燃料喷嘴中的脉动输出。 谐振管的脉动输出扰乱燃料喷嘴中的燃料流，有效地将其分解成分散的块塞或块，以便随后在燃烧室中燃烧。 通过燃料喷射的分解，提高燃烧效率以及减少不期望的排放，大大提高了燃烧过程。

摘要： 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 bimodal agglomeration of particulates which may be collected and removed using a conventional separation apparatus. A particulate having a size different from the size of the particulate in the gas stream to be cleaned is introduced into the system to effectuate the bimodal process. 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, the added particulate may be 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.
