| Summary: | Заглавие с экрана During the combustion of coal dust, ash and solid particles of unburned fuel are formed. As a rule, such particles are carried away by the flow of exhaust flue gases and settle on heating surfaces. This phenomenon leads to an increase in the resistance of gas ducts, thereby worsening heat transfer and leading to local overheating of the walls of the boiler unit. One way to solve this problem, as well as increase the efficiency of fuel combustion, is the combined combustion of coal and coal-water suspension. This study is aimed at studying the processes of interaction of droplets of coal-water suspensions with solid coal particles. Analysis of experimental studies showed that a decrease in the mass concentration of coal in the suspension leads to an increase in the number of secondary fragments. This effect is explained by a change in the physical properties of the liquid, namely a decrease in viscosity and surface tension Текстовый файл |
