Abstract

Invention m. B. used in. heating systems for open heating systems. The purpose of the invention is to improve the reliability and cost-effectiveness of installation. Hot water boilers 1, 2, 3 installations with inlet and outlet nozzles 4 and -5 are connected respectively to the inioioify and outlet headers B and 7 from the source water. Tank 9 make-up pods with: (United piping 14 with make-up - pump 11 with return pipe 12 in front of the network pump 13. Tank 9 is connected to pipe 14 with pipe 4 of boiler I, separated from the inlet manifold b by shut-off valves 15. Piping 14 is on pump 16 with a pressure characteristic not less than the corresponding characteristic of the network pump 13. During the start-up of the heat supply system, the contaminated network water ije passes through the surfaces of boilers 2 and 3, and only clean feed water is passed through the boiler 1 Water, preventing the heating surfaces of boilers from skidding.

; 1 1 is referred to as heat transfer coil linKC and M11 can be used in the boiler of the first heating boilers installed for open heating systems. 11el () YuPafeing is increasing n; 1dsa 11th and cost-effectiveness by preventing the heating surfaces of the boilers from slipping into the non-starting period of the heat supply system.

The drawing shows the scheme vodb-. | her boiler installation ..

The boiler plant contains water-heating: Vbie boilers I-3, each of which is supplied with inlet 4 and outlet 5 branch pipes-1LI, connected respectively to the inlet-Ume 6 and outlet 7 collectors with evoi water, connected in each boiler. -3 between its own bypass 8, ak 9 of make-up water, connected by pipe 10 to a feed pump II with return pipe 2 before: a net pump 13. The tank 9 is connected by an additional pipe 14 to the inlet pipe 4 of the boiler 1, separated from the inlet pipe of the collector 6 shut-off valves 115. In pipe 14, a pump 16 is turned on with a characteristic characteristic, we are smaller than the corresponding characteristic of the network 13, ...,,

Water boiler installation works as follows.

During the start-up of the tenl supply-PI system, when there is a lot of contaminating impurities in the supply water and the heat load of the boiler plant is relatively small, the boiler 1 is in operation, to which pump 16 feeds from the tank 14 from the tank 9 .weighted water treatment. The armature 15 is closed. Masos 11 is only operational when the flow rate

water surpasses throughput; the boiler 1. Cot.chys 2 and 3 are turned off, the network is passed water through: Lecturer 6 to the output collector 7 through nx bypasses 8.

Thus, during the start-up of the heat supply system, the network water does not pass through the heating surfaces of the boilers 2, 3, and only clean equipment passes through the working boiler 1; accurate water.

As the hydraulic regime stabilizes, contaminants decrease in the supply water due to the heat supply system and other measures, as well as increasing the heating load, boilers 2 and 3 are activated.
