description: In this thesis, design solutions were developed for the reconstruction of the district heating boiler house of the city of Otradnoye in the Kirovsky district of the Leningrad region with an increase in the attached heat load. The description of the boiler house before reconstruction is given. The design thermal loads of heating and hot water supply systems are determined. The installed thermal capacity of the boiler house after reconstruction is 18.5 MW. A qualitative method of regulating the seasonal heat load with a temperature schedule of 95-70 Â°C has been adopted. The main fuel is net natural gas, there is no backup (emergency) fuel. The thermal scheme of the boiler room has been developed. The heat-tube water-heating boilers produced by the Belgorod Boiler Plant with a single capacity of 3.5 MW and 5 MW were selected. A feature of the thermal scheme is the presence of an intermediate boiler circuit operating on a schedule of 113-70 Â°C. The preparation of the mains water flow occurs due to three-way mixing valves. The load of the hot water supply is combined with the transfer of the water flow to consumers through a dedicated two-pipe heat network with a recirculation line. The project of reconstruction of the head section of the thermal magi-stral was carried out in connection with an increase in the thermal load. The technical and economic indicators of the boiler house reconstruction project have been determined. The simple payback period is 10.5 years.
