Dimensionamento de câmara de combustão para microturbina derivada de turbocompressor automotivo

Abstract

Gas turbines are well known for their in industrial and propulsion application. However, they have gained prominence due to their increasing potential for versatile power generation. This is due to the increase of energy demand, as well as cogeneration and distributed generation (DG) applications. Moreover, microturbines have grown in use recently. Some of the advantages, which make the microturbines stand out, are related to their considerable low cost and simplicity if compared to other power systems. Even though microturbines have been researched in countries as the U.S.A., few studies on how to design microturbines with different arrangements are found in the Brazilian scenario. This work demonstrated the application of a methodology developed for the design of high power capacity gas turbines for the design and project of a combustion chamber of a microturbine derived from an automotive turbocharger. Furthermore, the steps of calculation, as well as the specifications defined for the combustor are presented. The final project of the liner is displayed and compared to the literature.
