INTEGRATED LEAN LOW EMISSION COMBUSTOR DESIGN METHODOLOGY (INTELLECT D. M.)

Objective

The objective of this proposal is to develop a design methodology for lean burn low emission combustors to achieve a sufficient operability over the entire range of operating conditions whilst maintaining low Knox emission capability. A knowledge based design system will form the framework to capture existing combustor design knowledge and knowledge generated in this project. Through pressing demand for emission reduction, very ambitious future Knox reduction targets of 80% by 2020have been set. Existing design rules, for conventional combustion systems, cannot be applied for lean low emission combustors. It is therefore important to- embody new design rules quickly, so that the- new technology can be incorporated faster into future products. The aim is to create the first building blocks of such an integrated combustor design system. The system will incorporate preliminary design tools to- make first estimates of the arrangement for lean burn combustion, which meets- operability, external aero-dynamics, cooling and emissions needs. Guidelines for the design of lean low Knox combustors for reliable and safe operation will be derived. Incorporation of these guidelines for lean low Knox combustion in the knowledge based combustor engineering tool in order to strengthen European competitiveness by reducing development costs and time. Lean blow out limit, ignition and altitude relight will be investigated. The airflow distribution and the aero-design of pre-diffusers for lean low Knox combustion with up to 70% air consumption will be optimised. Wall temperature prediction and testing for highly efficient cooling design will be performed. An assessment of generated knowledge and implementation in the knowledge-based system will take place. The new lean burn concepts have to gain customer and market acceptance to be fully competitive. Answers toprinciple questions concerning the operability and airworthiness of low NOx combustors will be given.
