This work contributes to the ecological solution of synthetic gas combustion. The methods and tools that were used to research this topic are briefly described in the article. For the study, two programs were used and stabilizers were considered in terms of angular parameters. The angular stabilizers' dimensions and the optimal aerodynamic cross-section behind the stabilizer were calculated using numerical simulation in the «COMSOL Multiphysics» program. This article also describes an experimental bench for burning syngas in a burner device. Due to the low-reaction characteristics of synthetic gas, its composition is variable. In this regard, to efficiently burn synthetic gas of various compositions, it is necessary to select the optimal angle of stabilizer inclination. During the experiments, the effect of angular stabilizers on the stabilization process, the efficiency of burning synthetic gas due to stable combustion, and the reduction of harmful emissions were investigated. Three different stabilizer angles (45°, 60°, and a semicircle) were presented on an experimental bench to find the optimal stabilizer angle for stable combustion with reduced nitrogen oxide emissions. As a result of the observation, it can be concluded that the combustion completeness of synthetic gas in burner devices depends not only on the angle of the stabilizer, but also on the coefficient of the incoming air, and this, in turn, affects the temperature level of the gases in the combustion zone.
