Enhanced electric field effect on a flame

The results of a laboratory and both industrial experimental investigations of the interaction between a propane flame and external radial electric field are presented in this paper. The effect of the radial electric field on a flame is found by the local measurements of a flame temperature, composition and radiation of gas compounds. It is obtained that the external electric field and flame interaction markedly affects processes of a free electron and ion transfer in a field direction. The intensification of a free electron transfer results in a more intensive excitation, dissociation and chemical interaction of gas compounds, while an intensification of a transfer of positive ions by an external field results in an enhanced heat and mass transfer in a field direction. In fact, the processes of interrelated heat and mass transfer are accompanied by the deformation of a radial and longitudinal distribution of a flame temperature and composition. The optimal conditions of a field and flame interaction for achieving an increase in a heat efficiency of district heating boiler houses with simultaneous reduction of NO_x and CO emission in atmospheric pollutants are examined.
