Abstract: Aspects of the disclosure include methods and systems for the de-icing of pulse filters, such as those used in turbomachinery. A method according to the present disclosure can include: coupling a filter bag to the pulse filter such that the filter bag is in a contracted position, the filter bag having a complementary geometry relative to the pulse filter, such that the filter bag occupies an airflow cross-section of the pulse filter, and wherein the filter bag is composed of one of a hydrophilic material, a hydrophobic material, or an oleophobic material; and pulsing a compressed air through the pulse filter and the filter bag during operation of the gas turbine, such that the filter bag expands to dislodge ice from an outer surface of the filter bag.
