description: At modern thermal power plants, the steam necessary for the operation of the turbine is generated by boiler plants. The purpose of this work is the creation of a project for the E-420-13.7-550 steam boiler, operating on lean coal from the Podgorodnenskoye deposit and providing the specified parameters of superheated steam. The project includes a thermal calculation of the boiler unit, during which the boiler was assembled with heating surfaces and the parameters of the media passing through the steam-water and gas paths are calculated. For a given working mass of fuel, the volumes and enthalpies of combustion products necessary for design are calculated. The design of burners, as well as the speed of primary and secondary air, is determined. For the E-420-13.7-550 boiler, a zone-by-zone calculation of the combustion chamber was performed, which makes it possible to determine the temperature of the combustion products at any height of the furnace. The resistance of the gas path of the boiler was calculated and the choice of exhausters was made. For flue gases emitted by the boiler unit into the atmosphere, the values of mass concentrations of harmful emissions are determined, which are compared with standard environmental indicators. The result of this work can be used by project organizations and constructors on thermal power plants for the designing of new and reconstruction of existing boiler plants working on lean coals.
