1. A gas turbine part, especially combustor part of a gas turbine, comprising a wall, which is subjected to high temperature gas on a hot side and a near wall cooling arrangement, with the wall containing a plurality of near wall cooling channels extending essentially parallel to each other in a first direction within the wall in close vicinity to the hot side and being arranged in at least one row extending in a second direction essentially perpendicular to said first direction, whereby said near wall cooling channels are each provided at one end with an inlet for the supply of cooling air, and on the other end with an outlet for the discharge of cooling air, whereby said inlets open into a common feeding channel for cooling air supply, and said outlets open into a common discharge channel for cooling air discharge, said feeding channel and said discharge channel extending in said second direction, said feeding channel being open at a first end to receive supplied cooling air and guide it the row of cooling channel inlets, and said discharge channel being open at a second end to discharge cooling air from the row of cooling air outlets, and means are provided within said near wall cooling arrangement to equalize the cooling air mass flow through the near wall cooling channels having a common feeding channel and/or discharge channel.
