ENHANCED ELECTRIC-FIELD EFFECT ON A FLAME

The results of a laboratory and both industrial experimental investiga tions of the interaction between a propane flame and external radial e lectric held are presented in this paper. The effect of the radial ele ctric field on a flame is found by the local measurements of a flame t emperature, composition and radiation of gas compounds. It is obtained that the external electric held and flame interaction markedly affect s processes of a free electron and ion transfer in a held direction. T he intensification of a free electron transfer results in a more inten sive excitation, dissociation and chemical interaction of gas compound s, while an intensification of a transfer of positive ions by an exter nal field results in an enhanced heat and mass transfer in a held dire ction. In fact, the processes of interrelated heat and mass transfer a re accompanied by the deformation of a radial and longitudinal distrib ution of a flame temperature and composition. The optimal conditions o f a field and flame interaction for achieving an increase in a heat ef ficiency of district heating boiler houses with simultaneous reduction of NOx and CO emission in atmospheric pollutants are examined.
