Coal-water fuel from brown coal.
In the last decade, the tendency to replace hydrocarbon liquid and gaseous fuels with coal has become increasingly clear, which is associated with the high shortage of hydrocarbon fuel and constantly rising prices for it. The increase in the specific share is evidenced by the constantly growing volumes of coal production.
Widespread introduction of a new type of liquid fuel from coal – coal-water fuel can serve as the basis for an effective replacement of expensive, scarce, environmentally friendly natural energy sources (natural gas and oil) at many thermal power plants and state district power plants with minimal capital costs and maintaining the required level of harmful emissions into the atmosphere.
The economic attractiveness of the VUT technology is as follows: it allows to reduce the use of natural gas for heating and generating thermal energy in the power industry, industry, housing and utilities by 25-30%, to increase the efficiency of heat generation by 30-40% compared to traditional coal combustion technologies. It allows to reduce the cost of thermal energy and eliminate the risk of coal dust explosion and spontaneous combustion of coal. It is a safe fuel for transportation and unloading. It improves the combustion process and reduces the temperature in the combustion zone, and also minimizes emissions of harmful substances into the atmosphere during combustion.
The conducted scientific research allowed us to propose a technological mode for obtaining suspension coal fuel based on brown coal by carrying out its preliminary modification and showed the possibility and economic feasibility of its use as an energy carrier. The obtained fuel can be recommended for use as an alternative boiler and furnace fuel in the public utilities sector, as well as for a number of heat and power generating enterprises.
