Control of the fuel supply system is remote (from the operator's room) using a computer. The necessary information about the status of the fuel dispensers is displayed on the display screen. For fuel storage, underground steel double-walled horizontal cylindrical tanks with a capacity of 50 m3 (5 pcs.) were chosen for gasoline and diesel fuel, three of which are separated by a double-walled partition into 2 volumes of 25 m3 each. Tank designs exclude the possibility of their depressurization and fuel leakage. The tanks have an anti-corrosion coating and are equipped with the following devices: manhole hatch; the breathing pipeline with a valve and a flame arrester is brought out above the ground by 5,75 m; drain pipeline with quick coupling and flame arrester; pipeline for measuring rod with quick coupling; automatic level control system; - a system for monitoring the state of the interwall space. Draining of fuel into the tanks - through drain devices installed in the drain well (flame arrester, drain quick coupling). A system has been designed for the return of gasoline vapors from the tanks into which the discharge is carried out to fuel trucks. To drain the fuel into the tanks, buried steel pipelines were chosen, laid along the “pipe in pipe” system and protected from static electricity. To supply fuel to fuel dispensers, polyethylene pipes laid on a geomembrane and steel pipelines are used. To collect emergency spills, an emergency tank with a capacity of 10 m3 is installed. Fuel delivery is provided by motor transport - AC with a capacity of 40 m3 (5 compartments of 8 m3 each). In accordance with NPB 111-98* 8x1.1=8.8 m3. Estimated parameters of outdoor air for design: for the cold period of the year, the parameters "B" -26 ° C; for the warm period of the year, parameters "A" +20,5 ° С; parameters "B" +24,6 °С. Water heating system - two-pipe horizontal, with counter-flow of the coolant. The source of heat supply is an electric boiler with an estimated temperature of the heat carrier for heating T = 95-70С. Laying pipelines - above the floor. To distribute the estimated flow rates of the heat carrier between the branches of the heating system, manual balancing valves USV-I from Danfoss are provided, which are installed on the supply branches. Control valves RTD-N are installed to control the heat transfer of devices. Emptying the system - through the drain cocks on the highways. Removal of air from the heating system is provided through an automatic air vent on each device. For the device of the system, plastic pipes of the REHAU company were chosen. The supply and return main pipelines are insulated with Energoflex polyethylene foam products only near the outer gates. To prevent the entry of cold air into the washing room, cut-off curtains are installed at the gate.
