description: Steam boilers are an integral part of thermal power plants. Superheated steam is produced inside steam boilers. The consumption of electrical and thermal energy is constantly growing, so this type of units will be in demand.In this work, the thermal calculation of the boiler unit E-250-13,7-560, consisting of design and verification calculations. The purpose of the design calculation is to determine the dimensions of the furnace of the boiler and itâs heating surfaces. The verification calculation has been performed to determine the temperatures and thermal perception of the working fluid, gaseous medium and air at the boundaries of each heating surface. The results of this work can be used in the working and educational design of boilers, their combustion furnaces and heating surfaces for burning brown coal. Similar to the recommendations for the application of the results of this work can be the design of U-shaped steam boilers. The use of the obtained results is possible when assessing the environmental indicators of boilers in accordance with normative. In this work, theoretical research methods were used (theoretical analysis, combining previously obtained information and obtaining new information).The values of volumes and enthalpy of combustion products have been investigated in order to calculate the capacity of the boiler. A position calculation had been also performed, the basis of which is the determination of gas temperatures to calculate their local thermal loads along the height of the furnace based on the equality between heat release and heat exchange of the combustion furnace zones. The cross-sectional areas of the burner devices for the dust-air mixture and secondary air have been determined. The strength calculation of the drum wall thickness had been made. All of the normative indicators for harmful emissions into the atmosphere are observed.
