10.1. Administrative building and fire station The category of heat consumers in terms of reliability of heat supply and heat release is the second. Diesel fuel Qnr = 10,200 kcal / kg is accepted as the calculated fuel. Water from the household water supply system is used as the source water. The heat carrier is water with parameters of 90-70°C. The thermal scheme of the boiler house provides for the release of heat for the needs of heating systems. The boiler room is equipped with two Drago Dual 23 steel hot water boilers running on liquid fuel. Flue gases through metal flues enter the chimney D=150 mm; H=6.0 m. The thermal scheme of the boiler house includes a system for emptying and purging boilers, draining from the lower points of pipelines, and removing air from them. All drains and purges are discharged into the ladder. To compensate for leaks, the heating system is supplied with water by automatically switching on and off the make-up pump based on a pressure pulse in the return pipeline. Fuel from the fuel tanks V=7.0 m3 is piped to the fuel filters, the flow tank V=0.2 m3 and the burners. Boilers are equipped with a burner with a blast fan. Operation of boiler burners is automated. Automation devices are supplied complete with boilers. Fuel consumption per boiler is respectively: in the cold season – 4.9 tons / year; in the warm season – 0 tons / year. 10.2.
