    Abstract

    The utilisation of sludge gas from sewage treatment plants13; a a fuel for asro-derivative gas turbines has h e n proposed as amp; means for power generation. A demonstration plant using a Rolls Royce Dart 514/7 turboprop engine i a Ming sit up at the sewage treatment plant at K amp; C Valley, Bangalore. The main modification to the engine pertains to the fuel injection system. A test rig based on a single Dart 514/7 combustor was set Up at the sewage treatment plant and combustion characteristics of various gas injector nozzles were studied. 'Tests with normal13; liquid fuel were also performed (in the Combustion and13; gas dynamics Laboratory) for comparison. The results for13; temperature traverse at combustor exit indicate that the temperature-traverse quality factor (TTQF) is quits high (0.32 0.46) by modern standards. However, it gas injector with a radial slit of 1.5 significantly lower than the values obtained with original injector, may be achieved when operating on sludge gas.width, the TTQF is significantly lower than the values obtained with original injector, This result suggests that a longer turbine life
