Dynamics of radiative, near-limit, stretched premixed flames is investigated analytically and numerically. Investigation of counterflow premixed flames stability is important for the development of new combustion technologies such as those associated with low-NOx emission, lean burn and material synthesis. Emphasis is paid on the linear stability of multiple flame regimes. The present analysis, for the first time, gives out a dispersion equation describing growth rate of small spatial perturbations of the flame front. The stability diagram is obtained and the region of instability is distinguished.

In this work, physicochemical features, thermal behaviour, and combustion properties of a coal dust of Pavlovskiy brown coal were studied. For investigations of kinetic properties of fine coal particles combustion, the laboratory-made setup was developed and constructed. An experimental research on the properties of fine coal particles was carried out. Additionally, thermophysical characteristics of coal dust, compositions of thermal decomposition products and particle size distribution were investigated.
