Experimental and numerical studies of combustion process in a vortex flow device have been developed. The modelling part of the study has been performed by means of ANSYS Fluent package. Fuel droplet trajectories and the flow pattern on their motions have been modeled by the function ?injection?. The combustion process utilized the k-? turbulence model. A special trend on the effect of the vortex generator blade orientation on the gross process has been developed. It has been established that optimal process performance (high air excess ratio and low NOx emissions) could be attained with an angle of the vortex generator blade orientation, especially with respect to the minimization of NOx emissions.

“…The test results presented in this paper were obtained for a lean biogas/air mixture, and relate to flame front velocity, temperature profile, emission, and flame structure. [10,19] The flame structure and combustion emissions [17], with a laminar premixed flame, of a lean biogas/air mixture [14] at an initial temperature of 298 K and a pressure of 1.013 x 10 5 Pa were calculated. The calculation was performed in the domain of 10 cm, which is significantly more than the thickness of the flame.…”

The paper presents results of theoretical numerical research dealing with CO and NOX emission performed in the process of optimization of the performance of low-power atmospheric burners. The theoretical part of this paper, whose main goals were better understanding of the complex issues of methodology and establishment of performance prediction and optimization of low-power atmospheric gas burner included numerical variation of independent parameters, such as burner geometry, the coefficients of primary and secondary air and different gaseous fuels including biogas. The findings of theoretically obtained performance prediction and optimization of atmospheric burners were experimentally investigated in purpose built test rigs for a number of variable parameters. The obtained results fully justified the proposed models of performance prediction and burner optimization.

Metal plate heating by new microflare burner has been studied experimentally and by CFD simulations, additionally, concentrations of NOx were measured to compare conventional and microflare burners. In addition, the article provides a numerical simulation of the combustion of a microflame burner. It has been demonstrated that microflare burners are more efficient and allows more uniform heating of metal plates. The comparison of NOx concentrations of conventional and microflare burners indicate better performance of the latter.
