Performance Evaluation of Combustor by Using Different Swirler
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
The main objective of this investigation is to obtain physical insight of the main vortex responsible for the efficient mixing of fuel and air. Such models are necessary for predictions and optimization of real gas turbine combustors. Air swirler can control the combustor performance by assisting in the fuel-air mixing process and by producing recirculation region which can act as flame holders and influences residence time. Thus proper selection of a swirler is needed to enhance combustor performance and to reduce NOx emissions. Three different axial air swirlers were used based on their vane angles i.e. 30°, 45°and 60°. Swirl is used in vortex burners and chemical reactors to stabilize the flame front and to increase the surface area across which heat and mass transfer exchange occurs. The Swirler Vane angle and Number of swirl vane exert much influence on the size of recirculation in the dome of combustor and little influence on the velocity distribution of centre line in the recirculation zone. Experiment Performed on the combustor by using different Swirler and its effect on combustion temperature along with axial distance by the use of air swirler and without swirler at same mass flow rate by using diesel as fuel. The result on the performance indicate that as atomizing air pressure increases there will be increase the combustion temperature. Swirler play important role in the fuel atomization and hence emissions were decreases at the same time combustion efficiency were increase.
