Technology and Equipment for Obtaining of Universal Hydrocarbon Fuel

Abstract

An analysis of methods and equipment for obtaining hydrocarbon fuel was carried out. The purpose of the work is the development of technology and heat-mass exchange equipment for the production of universal hydrocarbon fuel, suitable for use in all types of thermal power plants. Heat and mass exchange equipment has been developed, with the help of which it is possible to obtain universal hydrocarbon fuel with a maximum size of coal particles no larger than 3 microns. The use of water-coal suspensions as an energy fuel allows to increase the technical, economic and environmental indicators of power plants. Thus, during the transition to coal-hydrogen fuel, it was possible to increase its thermal capacity from 13.2 to 21.1 MW when 70 % of coal was replaced by coal-hydrogen fuel. Currently, there are various methods and equipment for the preparation of hydrocarbon fuel. However, they all have certain drawbacks. The main disadvantages of the methods of obtaining hydro-coal fuels are multi-stage, metal-intensive, high energy costs, carrying out physico-mechanical and expensive chemical demineralization of coal, etc. Also, the disadvantages are the limited frequency of hydraulic shock pulses during processing in one cycle, which is insufficient when preparing highly concentrated suspensions that meet the requirements for liquid composite fuel intended for direct combustion. In order to improve the quality of the resulting suspension due to more effective grinding and increasing the amount of its solid component, heat and mass exchange equipment was developed, which can be used to obtain universal hydrocarbon fuel for burning in boilers, furnaces, various thermal power equipment, internal combustion engines, etc. As heat and mass exchange equipment, rotary pulsation devices operating according to the method of discrete-pulse energy input were used.
