A storage tank 5 of hot water is installed on the boiler 7 of hot water supply. The furnace 9 of the hot water boiler is provided by the flue pipe 4 of the heating boiler 1 to the furnace 2 of the latter. Due to the presence of an additional firebox, an uninterrupted supply of hot water is provided at any time of the year. 1 il.

Description

/

The invention relates to heat supply and can be used in homes with an autonomous solid-state heat generator.

The aim of the invention is to save fuel and increase maneuverability.

The drawing shows a schematic diagram of the system.

The system contains a heating boiler 1 with a furnace 2, a cavity 3 for heating water and a chimney 4, a hot water storage tank 5 inside which a water heater b is located, a hot water boiler 7, whose flue pipe serves as a water heater 6 and passes inside the storage tank 5. The latter is installed by the bottom 8 on the furnace 9 of the boiler 7 of the hot water supply, communicated by means of the chimney 4 of the heating boiler 1 to its furnace 2. The system also contains dampers 10 and 11, a movable nozzle 12 connecting the chimney of the boiler 7 from the attic A typical chimney 13, water inlet and outlet connections 14, heat insulation 15 and doors 16 for loading fuel and removing ash.

The system works as follows.

In the warm season, the heat insulator 15 is installed on the battery tank, the valve 10 is closed and the fuel in the furnace 9 is burned. Since the furnace 9 is located in the immediate vicinity of the battery tank, most of the heat generated in the form of an open flame and high temperature gases It is transmitted through the bottom 8 and pipe walls of the boiler 7 to heated water, which is heated to 70-80 ° C. After the cessation of burning, the shutter 11 can be closed. At the same time, round-the-clock supply of hot water is provided, since the heated water is kept for a long time in the heat-insulated storage tank 5.

During the heating season, the doors 16 of the furnace 9 are closed, the valve 10 is opened, part of the heat insulation 15 is removed, and the fuel is burned in the furnace 2

boiler 1 heating. At the same time, the temperature of the gases leaving the furnace 2 is low (about 100-200 ° C), since most of the heat is transferred through the walls of the boiler 1 to the heating system.

However, since the fuel is burned for a long time, the water in the storage tank accumulates heat and gradually heats up to the required temperature of 70-80 ° C. Overheating of the storage tank 5 is prevented by emitting its open outer surface. The amount of heat loss can be selected by changing the surface of the thermal insulation of the storage tank 5.

Thus, during the heating season, uninterrupted hot water supply is provided by the utilized heat of the exhaust gases of the heating system. In addition, the heat accumulated in the accumulator bank 5 may produce additional heating of the room when the fuel burns out at night.

The proposed system provides year-round hot water supply. By utilizing the heat of the exhausting hot gases of the heating boiler, considerable fuel savings are achieved.
