<p>A thin 20m long pipe (16) is inserted through a plenum (13) into the combustion chamber (15). A pressure recorder (18) is connected to the pipe. To avoid false measurements caused by pressure waves reflected from temperature steps, either different pipe diameters (D1,D2,D3) are used or a cooling gas flow through the pipe is provided with the coolant taken from the plenum.</p> |
