Description

The invention relates to the heating systems of individual residential and public knowledge, to heating boilers.

For heating individual houses and cottages, as well as small administrative and production buildings npHM € HflK f various systems of individual heating - air, radiation, water, boiler or water with heating appliances. The most common water heating systems.

One of the main elements of such systems is hot water boilers. There are cast-iron and steel welded water heating boilers. Cast iron boilers have a long service life, due to a change in the number of elements (sections), they allow to gain any heating surface (thermal power). However, they require high-quality fuel. Therefore, it is currently preferred to use steel prefabricated boilers. These boilers can run on low-calorie fuel.

The closest technical solution adopted for the prototype is a hot-water boiler, comprising a housing, in the cavity of which a furnace with smoke tubes and heating and hot-water supply heat exchangers are located. The heat exchangers are made in the form of coaxial cylinders and are placed one in another. The smoke tubes of the furnace are located in the heating heat exchanger.

The redistribution of heat between the systems occurs through the separation wall and with the help of additional elements - brackets.

The disadvantages of the prototype are as follows: placing one heat exchanger inside the other limits the capacity (water volume) of the first: the heating surface of the brackets is much smaller than the cylindrical separation surface. Therefore, they have little effect on the amount of heat that is redistributed between the systems and on the circulation of water in the heat exchanger,

The purpose of the invention is to increase efficiency by increasing the storage capacity.

This goal is achieved by that in a water-heating boiler, containing a housing, in the cavity of which are placed a furnace with smoke tubes and heat and water heat exchangers, as well as elements of heat redistribution between the latter, and smoke tubes

The furnaces are located in the heating heat exchanger, the hot water supply heat exchanger is installed above the heating heat exchanger and is made with a bottom inclined to the horizontal, with the above mentioned heat redistribution elements connected to the lower and upper parts of the bottom, and the fire tubes are located in the heating heat exchanger at an angle to the horizontal.

FIG. 1 shows a general view of the boiler, a cross-section; in fig. 2 - section bb in fig 1; in fig. 3 shows section A-A in FIG. 2,

The boiler includes a housing 1, in the cavity of which are placed a furnace 2 with smoke tubes 3 and heat exchangers for heating 4 and hot water supply 5, elements 6, 7 of heat redistribution between the latter, and the smoke tubes 3 of the furnace 2 are located in a heat exchanger for heating 4, a heat exchanger for hot water supplies 5 is installed above the heat exchanger 4 and is made with the bottom 8 inclined to the horizontal. The said elements 6, 7 of the heat redistribution are connected to the lower and upper sections of the latter, and the flue pipes are located in the heat exchanger. ennike room heating at an angle to the horizontal.

The return heating water enters through the inlet 9 of the heat exchanger 4, is heated is discharged through the nozzle 10 of the heat exchanger 4. Hot water supply is supplied and discharged respectively via the pipes 11, 12. The grate 13 is provided for burning solid fuel. The outgoing gases are discharged through the gas outlet pipe 14.

The boiler works as follows.

The fuel is located on the grate 13, where it begins to burn. Its final afterburning takes place in the firebox 2. Through the walls of the firebox 2 and the fire tubes 3, the heat from the combustion of the fuel is transferred to the water in the heat exchanger through which the heating system water circulates. The heat of water in the heat exchanger 4 is also used to heat the water in the heat exchanger 5 of the hot water supply. While there is no water diversion from heat exchanger 5, heat accumulated from heat exchanger 4 accumulates in it. At the time of the water withdrawal, cold water enters through pipe 11 into the lower part of the heat exchanger 5. Wherefrom elements 6. 7 enters the upper part of the heat exchanger 5. displaced I feel water from it through pipe 12 to the consumer. After the cessation of water pumping occurs

Circulation of water in the hot water circuit. Cold water from the upper part of the heat exchanger 5 through element 6 is lowered into its lower part, heated here and element 7 rises again to the upper part of the heat exchanger 5. The slope of the bottom 8 contributes to directional stable circulation of water until the temperature in the water supply circuits is equalized and heated .

The proposed solution is suitable for boilers heated by various types of tolly and having different heat output.
