Description

The utility model relates to the field of heat engineering and can be used for heating and hot water supply of residential buildings, public buildings and industrial purposes.

Known boiler plant for external use, containing a thermally insulated fire tube boiler with nozzles of the forward and reverse water lines, a combustion chamber into which the burner nozzle is inserted, a chimney placed in a thermally insulated casing having openings for intake of external air, equipped with shutters with drives, while the boiler in the upper part it is equipped with heat-releasing fins for heating the air, an air temperature sensor located inside the casing in the immediate vicinity of the burner device and is intended for controlling blind drives (RF patent No. 2349844, IPC, 2007).

The disadvantage of this boiler installation is the need for a separate building in the heated building for placement and installation of circulation pumps (main and backup), shut-off devices on the forward and reverse lines, a dirt collector, a device for converting water hardness salts, a safety group (safety valve, automatic air vent , water pressure sensor switch, instrumentation). The allocation of a separate room inside a heated building and the installation of the above equipment in it increases capital financial costs and increases the cost of heat generated.

Closest to the utility model in technical essence, it is an outdoor boiler containing a thermally insulated body with a heat exchanger with direct and reverse lines, a burner, a chimney base, a circulation pump additionally equipped with an automatic valve with a constantly open nozzle, and the circulation pump is equipped with supply and suction nozzles and is located along the return line, while an automatic valve with a constantly open nozzle is located between inimitable pipes on the return line (RF patent No. 2436018, IPC F24H 1/00, 2010).

The disadvantage of this boiler, as well as the analogue considered, is the increased capital financial costs and increased cost of heat generated due to the need to separate a separate room for the installation of a backup circulation pump, shutdown devices, a device for converting water hardness salts, a safety group, and instrumentation inside a heated building.

In addition, the design of the boiler according to the patent of the Russian Federation No. 2436018, IPC F24H 1/00, 2010 does not allow the use of this boiler as a mobile stand-alone installation for heat production in emergency situations in central heating systems of housing and communal services.

The task the utility model aims to solve is to increase the reliability and safety of an outdoor boiler, reduce the complexity of building an autonomous heat supply system, reduce the cost of heat produced, create a mobile autonomous installation for generating heat in emergency situations in the housing system.

The technical result that can be obtained using the proposed utility model is to increase the reliability and safety of an outdoor boiler with a simultaneous reduction in labor costs in the construction of autonomous heat supply systems and a decrease in the cost of heat produced and, in addition, the creation of a mobile autonomous emergency heat supply installation.

The problem is solved, the technical result is achieved due to the fact that the outdoor boiler includes a thermally insulated casing with a heat exchanger with direct and return lines, a burner placed in it, while on the return line there is a disconnecting device, a dirt collector with a drain valve, a temperature measuring device and water pressure, a device for converting water hardness salts, a dual circulation pump (primary and backup), an automatic air vent is located on a straight line, safety valve, water pressure sensor, water temperature and pressure measuring device, disconnecting device, drain pipes from the mud collector, safety valve, heat exchanger emptying device are combined into a common drainage pipe, while the boiler is equipped with a control and alarm panel with a methane gas alarm.

In FIG. 1 shows a longitudinal section through an outdoor boiler.

In FIG. 2 shows a rear view of the outdoor boiler with the rear panel of the heat-insulated housing removed.

The outdoor boiler includes a thermally insulated housing 1 with front 2 and rear 3 opening panels, a heat insulated heat exchanger 4, equipped with a burner 5, direct 6 and return 7 water lines. On the return water line 7, a disconnecting device 8, a sump 9 with a drain valve 10, a device for measuring temperature and pressure of water 11, a device for converting water hardness salts 12, a dual circulation pump 13 with a primary 14 and a backup 15 working pumps are installed.

On a straight water line 6, an automatic air vent 16, a safety valve 17, a water pressure sensor 18, a temperature and water pressure measuring device 19, a disconnecting device 20 are installed. The heat exchanger 4 has a device for emptying water 21 and a smoke outlet 22. Drain pipes 23, 24, 25 from the sump 9, the safety valve 17, the device for emptying the water 21 are combined into a common drainage pipe 26.

On the front panel 2 there is a control and alarm panel 27 and a gas detector for methane 28.

The outdoor boiler operates as follows.

Mains water through the return water line 7, passing through a sequentially disconnecting device 8, a sump 9, a device for converting water hardness salts 12, the main pump 14 of the dual circulation pump 13, enters the heat-insulated heat exchanger 4, where it is heated by the flue gases generated by the combustion of gas in the burner device 5 and leaving through the flue pipe 22. When filling the heat exchanger with water, air from the cavity of the heat exchanger is removed through an automatic air vent 16. Heated mains water in a straight line water 6, passing the disconnecting device 20, enters the heat supply system of the building. In the event of an accident, the main pump 14 is automatically included in the operation of the backup pump 15.

If the permissible pressure in the heat exchanger is exceeded, the safety valve 17 is activated, and the water pressure sensor-relay sends a signal to the emergency service through the control and alarm panel 27.

If the permissible level of gas pollution on methane is exceeded, the gas pollution detector 28 transmits a signal to the emergency service through the control and alarm panel 27 and turns off the boiler.

This outdoor boiler has the following advantages:

- placement of the necessary equipment for autonomous heat generation inside a heat-insulated housing eliminates the need to separate a separate room inside a heated building for placement and installation of pumps, disconnecting devices, water hardness salt conversion devices, boiler safety groups, mud collector, instrumentation, which reduces capital financial costs and reduces the cost of heat generated;

- placement of the necessary equipment for autonomous heat generation inside the heat-insulated housing allows the proposed boiler to be used as a mobile autonomous installation for heat generation in emergency situations in central heating systems of housing and communal services;

- equipping the boiler with a dual circulation pump increases the reliability of transportation of the heating fluid;

- equipping the boiler with a device for converting water hardness salts eliminates scale deposits on heat exchange surfaces and increases the life of the boiler;

- equipping the boiler with a gas alarm for methane increases the safety of operation of the boiler.
