Gas Turbine Combustor (GTC) design is a challenging and time consuming process. Lacava, A.C.P. COMBUSTION CHAMBERS AND PERFORMANCE COMBUSTION CHAMBER: Combustion in the normal, open cycle, gas turbine is a continuous process in which fuel is burned in the air supplied by the compressor, an electric spark is required only for initiating the combustion process, and thereafter the flames must be self-sustaining. <>stream Join ResearchGate to find the people and research you need to help your work. The goal was to create a self-sustaining combustion within the engine. <> The cold water produced by the absorption chiller may be used for the air conditioning system of farm buildings. The investment costs of the ORC system and absorption chiller can be recovered in about 3 years by selling the extra electricity (100 kW) and by saving electricity required for cooling.

The present methodology deals with the computation of the initial design parameters and arriving at optimized values. The transient regimes in a combustion chamber has to be as short as possible because flame front position and thickness can destroy the combustion chamber in couple seconds. © 2009 by the American Institute of Aeronautics and Astronautics, Inc.
