description: Boiler units are an integral part of thermal power plants, in which superheated steam is produced for further use. The growing demand for energy makes such units in demand. The purpose of this final qualifying work is to develop a design for a steam boiler E-270-13.7-560, operating on brown coal from the Nazarovskoe deposit, which provides the specified parameters of superheated steam. The work included a thermal calculation, including design and verification stages. The design calculation determines the dimensions of the furnace and heating surface of the boiler, and the calibration calculation determines the temperature and heat perception of the working fluid, gaseous medium and air at the boundaries of the heating surfaces. During the implementation of the diploma project, various theoretical research methods were used, including theoretical analysis of previously obtained and new data. Boiler calculations include determining the volumes and enthalpies of combustion products, zone-by-zone calculation of gas temperatures and local heat loads along the height of the firebox based on the relationship between heat release and heat transfer in the combustion chamber. In the course of the work, the indicators of harmful emissions during boiler operation were calculated and the volume of the ash dump was assessed. This final qualifying work can be used as a basis for further research and development within the framework of the masters program. Its results can also be useful to designers and planners working on the creation of boiler units operating on brown coal.
