Abstract
Improving energy efficiency, operating and time availability of high power boilers is a continuous energy imperative, in parallel with the promotion of sustainable development. Such a need and focus, at the same time, is a strong motivation to explore new technologies for the conversion of primary energy from fuel. So far, significant research has been conducted at the University of Sarajevo - Faculty of Mechanical Engineering, Laboratory for Pulsed Combustion, on the accompanying properties of pulse combustion of propane-butane in a simple and robust modular burner, with fixed aerodynamic valves and cooled by water. The obtained results and findings clearly indicate that this burner can be usefully used as a basic and/or especially as an additional burner in the furnace with the aim of further turbulence of the combustion atmosphere and thus increase the efficiency of energy conversion from fuel. At the same time, the obtained results indicate that this burner can be used as a device for generating high-frequency oscillations of pressure and sound directly in the furnace and/or in the convective channels of high power boilers in order to prevent the formation or removal of already formed ash deposits from boiler heating surface.
