The project consists of nine work packages
The FLOXCOM Project is intended to develop technology for clean and efficient gas turbines, operating at high temperatures. It is based on the technologically innovative combustion solution -Flameless Oxidation. The investigation is directed towards the completion of the studies required to validate the engineering feasibility of incorporating the Flameless Oxidation technology in gas turbine combustors. The project aims at the development of an operating pilot combustors that will demonstrate, advantages including among others, improved performance relating to low NOx levels, maintaining uniform combustor wall temperatures, uniform fuel stream injection and more. This should also result in an increased Mean Time Between Failure (MTBF) and reliability of the gas turbine.
The project has reached its practical experimental stage. Measurements have already been performed and initial results have been achieved. The predictions and measurements are in relatively good agreement and clarified some issues concerning the internal physical behavior of the flow within the combustor.
In general, it can be said that aside of minor delays the project is carried out as planned and is advancing towards its goals of demonstrating the feasibility of FLOXCOM method. In the near future, experiments will commence at IST for atmospheric and reactive measurements and construction of the Ansaldo test rig will follow the approved final design. The design of the Pilot Combustor, based on the experience gained from the high-pressure sector system as well as the atmospheric system will continue from its current preliminary stage. Upon mutual agreement with the operator (RWTH)construction will be carried out followed by delivery of the system for testing of the pilot combustor. Design modification of the combustor characteristics will continue based on experience gained in the different studies including the wall cooling, fuel injection and vortical flow visualization.
