The physical characteristics of solid biofuel under combustion in a Rijke tube installation have been studied. A decrease in the flame temperature and an increase in the heat flux density on the tube wall on the occurrence of vibrating combustion were detected. To study vibrating combustion under conditions close to practical use in power plants, experiments were carried out on a "container–tube" type installation. The optimal parameters of the installation for the implementation of vibrating combustion of solid biofuels were obtained. A theoretical model of the development of sound disturbances of a combustion wave has been developed and its influence on heat transfer characteristics has been elucidated. An empirical-theoretical relationship has been obtained for calculating heat transfer in a Rijke tube during vibrating combustion. A model is proposed for calculating the amplitude of disturbances for instabilities in "container–tube" installations. [ABSTRACT FROM AUTHOR] |
