A method and arrangement for supplying a waste heat exchanger with exhaust gas from a gas turbine are provided. A first liner layer of titanium is deposited to a first thickness in the following manner. The Raman scattered energy and the fluorescence scattered energy, as well as the fluorescence energy lifetime are detected and analyzed to characterize or identify the substance. The final layer of the tape length is circumferentially wound around the penultimate tape layer so that the trailing end of the tape overlays the tab between the first and second ends of the tab. An apparatus for converting N-bit image data of a digital image into M-bit image data, in which NMK, K0, is also disclosed. The catalyst flux rate can be adjusted during the process of the reaction to adjust the space velocity and maintain a fast fluidized flow regime therein.
