The work describes the task of urgently converting the boilers of anthracite-burning combined heat and power plants to sub-bituminous coal, which arose in the conditions of Russian aggression in connection with the complete cessation of supplies of project fuel. The developed methods of solving it in a short time with the maximum use of available equipment are given, using the example of boilers with a steam capacity of 220 t/h of CHPP «EURO-RECONSTRUKTSIA» LLC (Darnytska CHPP, Kyiv). On the basis of calculation justification it is shown, and the tests and operation have confirmed, the safety and effectiveness of the technical solution with preservation of coal drying by hot air while limiting the temperature at the exit of the mill and with pulverized coal transport to the burners by half-heated air taken after the first stage of the air heater, while reducing the diameter of the pulverized coal pipes. Measures are proposed and implemented to equalize the distribution of pulverized coal and air among the burners, to operate the mills in alternating mode with the aim to increase the use of hot air, correspondingly to increase the coal jet temperature, to improve the conditions of molten slag removal and to reduce the temperature of flue gases, etc. Uninterrupted operation of the Darnytska CHPP became an important factor in ensuring the functioning of the critical infrastructure of heat and energy supply of Kyiv in conditions of enemy shelling.
