FIELD OF THE INVENTION

The invention relates to the field of heating systems, in particular to autonomous heating systems, and can be used for autonomous heating of multi-storey apartment buildings using non-volatile outdoor boilers.

State of the art

Known combined boiler containing a furnace device and autonomous inlet and outlet pipes, fixed in the tube sheets of the upper and lower drums with the formation of a heating and steam circuits, the upper drum of the steam circuit is partially filled with water, while it is equipped with a partially filled water tank-battery, placed in the upper drum of the water-heating circuit, and a pipeline, each of which is equipped with its own locking element, moreover, the storage tank and the upper drum of the steam circuit are communicated between through the mentioned pipelines, one of which is connected below the water levels in the tank and drum, and the other is above these levels, and the furnace device is made in the form of a rectangular chamber located above the burners in the area of one of the ends of the lower drum with the formation of side channels for cooling medium, while the boiler is equipped with a grate and a screen made of horizontal pipes and placed behind the furnace device (see US Pat. RU No. 2037093, class F22B 33/02).

The disadvantage of this combined boiler is the design complexity, high costs of heat production.

Known hot water boiler containing a housing with a combustion chamber, equipped with end-mounted burner and gas outlet, framed by outer, middle and inner annular sections of the heat exchange surface, connected to the inlet and outlet of water, communicated along the latter and located one in the other with the formation of annular gas channels communicated sequentially along the gases, moreover, one end of the middle section is equipped with a deflecting element located with gaps relative relative to the end of the casing in the area of the gas outlet pipe and, respectively, the end of the inner section, and the other end of the middle section is located with a gap relative to the end of the casing from the side of the burner device with the formation of an annular chamber between the outer and inner sections, while the casing is vertical, the combustion chamber is in the outlet made in the form of several flame tubes located in the upper part of the water cavity of the inner section, and the annular chamber is equipped with a condensate drain pipe (see A.S. SU No. 1719805, class F24H 1/32).

The disadvantage of this boiler is the design complexity, limited functionality.

The closest in technical essence and the achieved positive effect and accepted by the authors for the prototype is a heating system containing an outdoor boiler, an expansion tank, direct and return lines, risers and heating devices connected to the riser by pipelines (see "Calculation of central heating systems", author: R.V. Shchekin, V. A. Berezovsky, V. A. Potapov, Vishka Shkola, Kiev, 1975).

The disadvantage of this system is limited functionality, low operating safety.

Disclosure of invention

The technical result that can be achieved using the present invention is reduced to the autonomy of heating and hot water supply, regardless of the availability of electricity, system reliability and safety.

The technical result is achieved using an autonomous heating system comprising an outdoor boiler, an expansion tank, direct and return lines, risers and heating devices connected to the riser by pipelines, with at least two risers taken, and in the piping of each heating device in the riser node is equipped with a circulation accelerator, and the binding of the heating devices of the 1st floor is made according to a full-flow scheme.

The essence of the invention lies in the fact that the heating devices are tied with pipes of the same size as for systems with pump circulation, but a circulation accelerator is installed at the input of each heater. The devices of the 1st floor are performed without an accelerator in a full-flow circuit.

Brief Description of the Drawings

Figure 1 gives an autonomous heating system, a diagram of the natural circulation of the coolant in the riser of a 5-storey building.

In Fig.2 - the same device accelerator circulation of the coolant through the heating device, in which only the upper distribution of the coolant is applicable.

The implementation of the invention

The autonomous heating system consists of a straight line 1 with at least two risers 2, heating devices 3, a return line 4, while at the top of the heating system there is an expansion tank (not shown) connected by a straight riser 2 to the boiler (not shown ), each heating device 3 has a regulating device 5, moreover, the heating device 3 of the first floor is connected in a full flow circuit without a regulating device 5, each heating device 3, except for the devices of the first floor, in the riser node 2 contains an accelerator 6 of circulation at the beginning of wiring 7 heating devices 3, also each heating device 3 contains a tube 8 for draining the coolant.

Autonomous heating system operates as follows.

The coolant from the boiler along the vertical riser 2 enters the expansion tank and enters numerous risers 2 in a straight line 1, in the circulation accelerator 6, the kinetic energy of the coolant is partially converted into the energy of the circulation pressure and the coolant through the supply 7 enters the heating device 3, where it is cooled tube 8 for the removal of coolant through the control device 5 again enters the riser 2, where, mixed with a hotter coolant, it goes down and in the heating device 3 of the lower floor comes the same. On the ground floor, the coolant, which has lost a significant amount of heat, passes through a heating device 3 in a full-flow circuit and enters the return line 4 and then into the boiler. Thus, natural circulation of the coolant is carried out in an autonomous heating system of multi-apartment multi-storey buildings, while the reliability of heat supply increases by an order of magnitude, and, as practical tests of the circulation accelerator 6 have shown, the leakage coefficient of heating devices 3 has increased by 25% compared to risers made using traditional pattern.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- autonomy of heating and hot water supply regardless of the availability of electricity;

- reliability of the heating system;

- security of the heating system.
