description: In industrial power engineering, the steam boiler is an important element. Thanks to such boiler units, superheated steam is generated at thermal power plants for further operation in the turbine. The consumption of electrical and thermal energy is constantly growing, so this type of units will be in demand. In this work, a thermal calculation of the E-420-13.7-550 boiler unit is carried out, consisting of a design and verification calculation. The purpose of the design is to select the layout and determine the dimensions of all heating surfaces of the boiler unit. The purpose of the verification calculation is to determine the temperatures and thermal perceptions of the working fluid and the gaseous medium. In the final qualifying work, theoretical research methods were used (theoretical analysis, combining previously obtained information and obtaining new information). The results of this work can be put into practice for the working and educational design of boilers and its components (combustion chambers, heating surfaces) using brown coal. Application of the results can be used in assessing the environmental performance of the fuel. To calculate the boiler, the volumes and enthalpies of combustion products were calculated. The dimensions of the flow sections of the burners for the dust-air mixture and secondary air are determined. Methods for cleaning the heating surfaces from external deposits are selected. A zone-by-zone calculation of the combustion chamber was also made, the purpose of which is to determine the distribution of temperatures and local thermal loads along the height of the furnace based on the energy equation. To ensure regulatory environmental performance, harmful emissions during the operation of the boiler unit were calculated.
