description: The presented bachelors thesis is devoted to the project of a mini-CHP plant being created as part of a district heating boiler house. The description of the scheme and the main equipment of the boiler room, thermal loads of various types, a method for regulating seasonal heat load, and a temperature schedule for qualitative regulation are given. A scheme for the integration of a steam turbine into the thermal circuit of a boiler house along various flows has been developed. Calculations of the processes occurring in the main equipment of the mini-CHP are performed. The layout of the mini-CHP has been developed. The main attention is paid to the study of the method of connecting mini-CHP heaters via mains water to hot water boilers. For model tasks with sequential and parallel connection of the heater to hot water boilers, a mathematical description of the heating processes of mains water is performed. The distribution of mains water flows in the following lines has been determined: mini-CHP heater, hot water boilers, recirculation line, bypass line of hot water boilers. The number of working hot water boilers is taken into account when the heat load of the boiler room changes during the heating period. In all operating modes, the requirements for the operation of hot water boilers are met, and a temperature schedule for high-quality regulation of the 130-70 Â°C heat supply system is provided.
