The article substantiates the necessity and possibility of preserving coal in the power industry as a fuel of the future, using the appropriate technology, based, to a large extent, on the use of layered combustion technology. The advantages and disadvantages of coal combustion in a layer are analyzed. The need to switch to flaring coal combustion to increase the unit capacity of the boiler is noted. The universality of this method of coal combustion in relation to its thermal properties is indicated. The sources of problems with emissions into the atmosphere during coal flaring are given. Shown is the substitution of the concept of dirty technology with the concept of dirty fuel in relation to coal fuel. The ways of returning to the layered combustion of coal are indicated, with the provision of the required capacity of the power facility through the installation of an increased number of boilers with lower productivity. It is noted that at the Almaty University of Energy and Communications named after Gumakrbek Daukeev, a coal combustion technology with reduced disadvantages is being developed The possibility of using flammable volatiles contained in coal for kindling a boiler and for stabilizing the ignition of a coal flame is noted. the possibility of supplying residents of a remote village with their own gaseous fuel for cooking was considered. The possibility of using this gaseous substance for the generation of electrical energy with the installation of low-power gas turbine units on a boiler with coal layer combustion is indicated. Based on such a comprehensive analysis of the advantages and disadvantages of coal, a conclusion was made about the long-term preservation of coal in the power industry.
