Abstract
THE PURPOSE. The features of the rheological behavior of composite fuel oil suspensions depending on the shear rate, temperature and composition of the composite fuel are considered.
METHODS. Suspensions with a coal content of 30, 40 and 50% (by weight) were prepared. The mixing time varied from 1 to 10 minutes. The samples of fuel oil were examined using a Rheomat RM 100 rotary viscometer to determine the values of dynamic viscosity at different shear rates and temperature.
RESULTS. The results of experimental studies of the dynamic viscosity of fuel oil as a function of the shear rate and temperature are obtained. The best values of coal dust content in fuel oil suspensions for fuel transportation have been determined.
CONCLUSION. The obtained research results can be used by both energy companies and transport companies to determine the technological viscosity indicators of composite suspension fuels used as boiler fuel and fuel for marine engines.
