| סיכום: | Title screen An experimental study has been made of the ignition of droplets of organic coal water fuels prepared from moist waste (obtained by the flotation technique) of coal washing and used industrial oils with the use of a high-speed system of video recording of the processes proceeding in a model combustion chamber. A comparison has been made between the ignition inertias characteristics of a single droplet of organic coal water fuels, a group of three droplets, as well as of a polydisperse flow of a slurry fuel. All experiments were performed for hovering droplets (upon dehydration of the surface layer they are considered as particles) of organic coal water fuels in a model combustion chamber filled with heated air (the temperature was from 800 to 900 K). The established differences between the ignition characteristics of the slurry fuels in the three investigated schemes illustrate the possibility of prognostic evaluation of ignition characteristics of droplet aerosols of organic coal water fuels with the example of a single droplet. We present the dependences of ignition characteristics of single hovering droplets of organic coal water fuels of various component compositions on the group of diagnostic variables (temperature and flow velocity of the oxidizer, initial sizes of droplets, and concentration of the component composition). The prospects of using the obtained experimental results to optimize the performance of power-generating plants are shown. Режим доступа: по договору с организацией-держателем ресурса |
