A vane 400 for a gas turbine air inlet filter 102 having a body that, when in position in the gas turbine air inlet filter, extends substantially in a direction of airflow. The vane has a length extending substantially perpendicular to the direction of airflow and has a plurality of channels 402, 404 each for holding an electrical trace heat element (808, figure 8). The channels are disposed towards and along an upstream edge 412 of the vane and are arranged in-line parallel to the direction of airflow. A method of heating a gas turbine air inlet is also described. Heat is provided at the gas turbine air inlet filter by means of electrical trace heating to raise the temperature at the gas turbine air inlet filter such that ice does not form, notwithstanding cooling due to acceleration of the airflow downstream of the gas turbine air inlet filter and into the gas turbine inlet. |
