description: The dissertation is devoted to the development of a boiler plant project with an E-420-13.7-550 boiler for working on lean coal from the Podgorodnenskoye deposit. Completed: design of the E-420-13.7-550 boiler, providing the specified parameters of superheated steam, development of a dust system and its arrangement with the boiler, design and selection of fuel equipment, calculation and design of burner devices, aerodynamic calculation of the boiler air path and selection of draft machines, calculation of the level of emissions of harmful substances, as well as the development of solutions to reduce them. The problems of increasing the operating efficiency of the boiler unit are solved by minimizing heat losses, optimal organization of the combustion process, promoting complete burnout of the combustible component of fuel particles in the combustion chamber. The specifics of the operation of the equipment elements of the boiler dust system have been studied, the most cost-effective modes of their operation have been identified, allowing to achieve a minimum of electricity costs for grinding fuel. Special attention is paid to the level of emissions of harmful substances during boiler operation, and a solution to reduce emissions of nitrogen oxides is proposed. The results of the work can be used in the design of new, reconstruction and operation of existing boiler plants operating on organic fossil fuels.
