description: The purpose of the final qualification work is to develop a boiler unit E-220-13,7-550, for working on the hard coal of the Bukachachinsky deposit. In this project, the fuel composition was analyzed and recalculated with a 2% humidity change. In addition, the thermal balance of the boiler unit was calculated, and the geometric dimensions of the combustion chamber were determined. Then a warm calculation of each of the heating surfaces was carried out. Also, during the thermal calculation, the geometric characteristics of the main heating surfaces (radiation, semi-radiation and convective) were determined. For boiler E-220-13,7-550 A position calculation of the combustion chamber was carried out, which allows determining the temperature of flue gases anywhere in the furnace. The resistance of the gas path of the boiler was also calculated, taking into account gravity, and the selection of smoke pumps was carried out. In addition, for flue gases, the values of concentrations of harmful emissions (sulfur and nitrogen oxides) were calculated, after which a comparison was made with the normative indicators. For high-quality operation and compliance with the set temperatures of superheated steam, equipment for cleaning heating surfaces was selected. The calculation of the drum of the boiler unit for strength has been performed. Based on this work, further research can be carried out to modernize boiler units in existing thermal power plants. Also, based on the final qualification work, it is possible to develop a plan for a new thermal power plant by choosing additional equipment of the unit and making a technical and economic analysis.
