“…The two-dimensional geometry file can be found in two formats, 'Geometry 2D.agdb' and 'Geometry 2D.igs', in the Supplementary Materials, for more details on the detailed dimensions and for modelling purposes. The air flow, which enters from a swirler air diffuser, could be assumed to be axisymmetric with a good approximation [24]. Calculations were applied according to the steady time solver.…”

Modelling and Optimization of a Small Diesel Burner for Mobile Applications

While extensive research has been done on improving diesel engines, much less has been done on auxiliary heaters, which have their own design challenges. The study analyzes how to optimize the combustion performance of an auxiliary heater, a 6 kW diesel burner, by investigating key parameters affecting diesel combustion and their properties. A model of a small diesel heater, including a simulation of fuel injection and combustion process, was developed step-wise and verified against experimental results that can be used for scaling up to 25 kW heaters. The model was successfully applied to the burner, predicting the burner performance in comparison with experimental results. Three main variables were identified as important for the design. First, it was concluded that the distance from the ring cone to the nozzle is essential for the fluid dynamics and flame location, and that the ring cone should be moved closer to the nozzle for optimal performance. Second, the design of the swirl co-flow is important, and the swirl number of the inlet air should be kept above 0.6 to stabilize the flame location for the present burner design. Finally, the importance of the nozzle diameter to avoid divergent particle vaporization was pointed out.

Ghiaus et al. [13] showed that combustion efficiency depended on the position of the nozzles. This paper presents the results of measurements conducted in a small thermal capacity power boiler room with a burner provided with different kinds of nozzles. The aim of the work was to define differences in pollutant emissions like NO and CO, depending on oil pressure and nozzle type. Methods and Experimental Object Description The experiments were carried out in northeastern Poland. The tested boiler had a nominal thermal capacity of
