THE RHEODYNAMICS AND COMBUSTION OF COAL-WATER MIXTURES
ABSTRACT
Special research methods were developed for studying a flow in a tube and the dynamics of the combustion and gasification of a single drop.
For a laser-heated small fuel particle, combustion dynamics and gasification were studied with automatic measurement and data processing for its temperature, and its photo-electric and gas-analytic
characteristics. From the combustion of a drop of coal-water mixture, we demonstrated that these methods enable the investigation of thermometric, pyrometric and concentrational dynamics for the combustion
of a single fuel drop. This technique gives us the total combustion time, it registers the duration of the combustion phases, the moment and the temperature of the drop's ignition, and it gives us information about the
combustion mass rate and the products of gasification. It is possible to control the duration of the combustion process through fuel composition in coal-water mixtures: the ratio of a fast-reactive component to a slow-reactive one.
