Effects of Flame Temperature on Combustion Instabilities of a Premixed Burner
Combustion instabilities in gas turbine has been a major setback in the quest for efficient and clean combustion. Accurate characterisation and prediction of these disturbances is required to suppress them either at the design stage or in a close loop control when the system is in operation. The use of flame transfer functions has been a common approach in different literatures. Flame temperatu...
متن کاملForced Response: Laminar Flat Flame Burner
Since a large number of physical parameters influence the flame dynamics in a full scale gas turbine combustor, it is virtually impossible to develop physically correlated reduced order models for flame dynamics by directly studying these complex reacting flows. Even the Rijke tube combustor system, though comprising of a simple geometry and a flat flame, shows a strong nonlinear coupling betwe...
متن کاملAn Experimental Investigation of Gas-Phase Combustion Synthesis of SiO2 Nanoparticles Using a Multi-Element Diffusion Flame Burner
The current work presents the results of an experimental investigation of gas-phase combustion synthesis of silica (SiO2) particles using a multi-element diffusion flame burner (MEDB, a Hencken burner). Silane (SiH4) was added to hydrogen/oxygen/argon (H2/O2/Ar) flames to produce SiO2 nanoparticles at various burner operating conditions ( 0.47–2.16). To characterize the burner performance, temp...
متن کاملDemonstration of Gas-phase Combustion Synthesis of Nanosized Particles Using a Hybrid Burner
A new approach for gas-phase combustion synthesis of nanosized particles using a novel hybrid burner facility is demonstrated. The basis of the synthesis technique is to use both a premixed flame and a diffusion flame to control the synthesis environment. Specific experimental results for silica (SiO2) production from silane/hydrogen/ oxygen/argon (SiH4/H2/O2/Ar) flames are presented. A paramet...
متن کاملPollutant Formation during the Occurrence of Flame Instabilities under Very-Lean Combustion Conditions in a Liquid-Fuel Burner
Recent advances in gas turbine combustor design are aimed at achieving low exhaust emissions, hence modern aircraft jet engines are designed with lean-burn combustion systems. In the present work, we report an experimental study on lean combustion in a liquid fuel burner, operated under a non-premixed (single point injection) regime that mimics the combustion in a modern aircraft engine. The fl...
