Abstract


Combustion chambers are used in energy systems mainly to increase heat transfer. In this paper, a modern design procedure of a combustion chamber of a boiler is presented, in order to improve temperature distribution over the combustion chamber borders, as well as the combustion dynamics such as interior pressure and combustion velocity. The design process is mainly based on changing the geometric aspects of the combustion chamber, more particularly the geometry of the bottom side. Thus, a simulation study using Fluent Software has been carried out on two main geometries, namely: a cylindrical combustion chamber with a flat bottom and another one with a convex bottom respectively. The simulation results have shown remarkable improvements in the combustion chamber in case of convex bottom behavior in terms of temperature distribution and heat transfer and therefore the good efficiency of the boiler
