  • Publication number: 20230390685
    Abstract: A gas turbine air intake system uses a filter element having a seal member with radial projections and radial recesses. The seal member forms a seal with components on the tube sheet of the system and at the end opposite of the tube sheet. At the end opposite of the tube sheet, there can be an assembly cover, or alternatively, an additional filter cartridge.

  • Publication number: 20230219029
    Abstract: Embodiments herein relate to filtration systems that can pulse clean filter elements selectively, in specific patterns, to enhance cleaning efficacy. In an embodiment, a filtration system is included having a plurality of filter element mounts configured to retain filter elements, a compressed gas supply, and a plurality of valves in fluid communication with the compressed gas supply. The system further including a control circuit configured to control actuation of the plurality of valves. The system can operate in a first mode and a second mode. Wherein operating in a first mode includes opening valves according to a first valve actuation pattern and operating in a second mode includes opening valves according to a second valve actuation pattern. The system can be configured to periodically switch from the first mode to the second mode and compare the efficacy of the two modes. Other embodiments are also included herein.

  • Publication number: 20220054965
    Abstract: Included herein are filtration systems that can proactively pulse clean filter elements in response to anticipated changes, such as anticipated changes in filtration performance or anticipated changes in filtration system demand. In an embodiment, a filtration system is included having a filter element mount for a filter element, a compressed gas supply, and a valve, wherein opening the valve results in a pulse of gas directed at the filter element. A control circuit can control the valve. A communications circuit can receive data related to an anticipated change, such as data regarding an anticipated change in filtration performance and/or data regarding an anticipated change in filtration system demand. The control circuit can execute operations based on the anticipated change data such as adjusting a pressure drop threshold and initiating proactively opening the valve in the absence of a pressure drop threshold being crossed. Other embodiments are also included herein.
