Thermophysics and Thermal Power Engineering| Summary: | Considering that the import of oil and gas is decreasing, the cost of their production and supply is increasing, coal in Ukraine is becoming almost the only source of energy of local origin. In order to overcome the critical situation in the fuel and energy complex of the country, trends have been outlined regarding the development and implementation of energy saving programs, as well as the creation and implementation of new, efficient, environmentally friendly fuel technologies. One of the main ones is the transition to widespread use of hydrocarbon fuel (HCF).
The purpose of the work is the analysis of existing technologies and equipment for the preparation of hydrocarbon fuel. Demonstration of the effectiveness of the cavitation effect on the water-coal mixture. To propose new technologies and heat and mass exchange equipment working on the basis of the DPIE method as a promising direction in the preparation of HCF.
When conducting an analysis of existing technologies and equipment for the preparation of hydrocarbon fuel, the effectiveness of the cavitation effect is shown. It was established that before cavitation treatment, coal must be dispersed on various types of grinding equipment to an average particle diameter of 1000-500 microns. It is most effective to carry out cavitation treatment of hydrocarbon suspension with the use of heat and mass exchange equipment operating on the DPIE principle. This makes it possible to obtain a universal hydrocarbon fuel with a particle size of no more than 3 microns, which is suitable for burning in various energy devices, as well as to reduce specific energy consumption by almost 3 times compared to supercavitating fuels. |
