description: The annual increase in the consumption of heat and electricity leads to the construction of new and modernization of existing power plants. An integral part of the station is the boiler unit. It is in it that superheated steam is generated for its subsequent use in the turbine. In this final qualifying work, thermal calculation, and design of the E-420-13,7-555 boiler is carried out for work under the program for the expansion and modernization of the Neryungri GRES. Thermal calculation includes design and verification calculations. The purpose of the design calculation is to select the layout and determine the dimensions of all heating surfaces, the verification calculation is to determine the temperatures and the perception of heat of the working fluid and flue gases. The results of this work can be used in the development and design of various kinds of technical documentation. The obtained data on the calculations of individual heating surfaces can serve to create real prototypes of heat exchangers. When designing a boiler unit, the volumes and enthalpies of fuel combustion products were calculated. The working mass of fuel was recalculated considering changes in humidity. The velocities of the primary and secondary air in the burners and the dimensions of the flow sections are also determined. For the E-420-13,7-555 boiler, a zone-by-zone calculation of the combustion chamber was performed, the purpose of which is to determine the distribution of temperatures and local heat loads over the entire height of the furnace. A strength calculation of the drum wall was made, the purpose of which was to determine the wall thickness. The calculation of the environmental performance of the boiler unit was carried out.
