Large Scale Low Pressure Dump Combustor Performance.
Abstract
An experimental investigation has been conducted extending previous results of small scale dump combustors to larger combustors (8 to 12-in D) tested at lower pressures. A parametric study was then conducted around the 12-in baseline configuration, with and without flameholders, in which combustor length-to-diameter (L/D), Combustor Length-to-step height (L/h), characteristic length (L*), fuel injector type, inlet temperature and chamber pressure were varied. Lean blowout limit, combustion efficiency, and combustor pressure drop were obtained from these runs using JP-4 fuel and compared to previous small scale data. A limited number of additional tests were conducted with Shelldyne-H fuel. Results show that good combustion efficiencies can be achieved with relatively low blockage flameholders resulting in higher overall performance for the larger combustors. (Author)
