Description

The device relates to heat engineering, namely, to household heating partitions and can be used for heating household separate buildings with an area of up to 250 square meters. m, as well as for heating food.

The closest analogue prototype is the device according to the patent of the Russian Federation No. 2039913 C1, which is a combustion chamber framed by a water jacket, with an installed grate under the combustion chamber, and a removable ash box, the device is equipped with an additional electric heater with a temperature sensor, thermal relay and starter, as well as guides in the ash chamber, where liquid fuel burners can be located.

The disadvantages of this device are the lack of a working surface for heating food, as well as the presence of removable burners for liquid fuel, which does not allow the simultaneous use of solid and liquid fuel. The nozzles are clogged with slag that falls through the grates; long firewood cannot be laid in the furnace, because the combustion chamber has a small length.

The task is to offer a household heating device in which solid fuel and liquid can be used at the same time.

The technical result is the ability to use both solid and liquid fuels for heating and cooking without changing the burners, as well as electricity.

Description of the drawings: FIG. 1 is a side view; Figure 2 - section aa in figure 1.

The technical result is achieved by the fact that a domestic hot water boiler has a steel case 1, Fig. 1, with double walls, the space between which is filled with a coolant, for example, boiler water or a mixture: ethylene glycol 20% and water 80%, while

a water shirt 2, Fig. 1, is connected to the heating system of the house by pipes 3, 4, Fig. 2. In the cavity of the housing 1, Fig. 1, a combustion chamber 5, Fig. 1 is installed, for burning coal and firewood, equipped with a door 6, a grate 7 made of hollow steel pipes 8, Fig. 2, which are also filled with a coolant and act as heat exchangers . Under the grate 7 there is an ash chamber 9, with a removable duct 10 and a door 11. The upper surface 12 of the combustion chamber 5 is made in the form of a cast-iron plate with two rings 13, which are closed by removable plate rings. Through the burners 13, you can load coal or put on them containers for food and water. One side surface, for example, of the right, combustion chamber 5, is the wall of the boiler 1 with a water jacket, and the other opposite wall 14 is made in the form of a heat exchanger from steel pipes 8 adjacent to each other and filled with a coolant and connected by ends to the front and rear walls of the water jacket 2 Fig. 1.

A tank 15, Fig. 1, is mounted on the steel casing 1 from the outside opposite the combustion chamber 5, for storing liquid fuel stocks, for example, used oil or any oil product, equipped with a drip type fuel supply system manual 16 and automatic 17. Tank 15 capacity no more 10 l Fuel from the tank 15 through the pipe 18 enters the cavity of the housing 1 at under 19, Figure 1. A door 20 is made in the housing 1, FIG. 2, for removing solid waste from burning liquid fuel and igniting liquid fuel, for example, used oil.

On the outer surface of the housing 1, next to the tank 15, there is a boost fan 20, FIG. 1, which supplies external air to the combustion chamber 21, in which liquid fuel is burned, while air is supplied through a pipe 22, which first passes horizontally through the combustion chambers 5 and 21 to the place of supply of liquid fuel, and then the pipe 22 is lowered vertically down through the chamber 21 to the hearth 19 to the place

where liquid fuel is supplied, the pipe 22 passes into a horizontal bend having a technological slot through which the air heated in chambers 5, 21 enters the surface of the liquid fuel spilled on the hearth 19, providing for the evaporation of light fractions of oil products and their combustion in the chamber 21.

The device has electric heating elements 23, FIG. 1, which are located in a water jacket 2 and are equipped with an external temperature sensor that determines the temperature inside the room, thermal relay, starter and short circuit protection system. Not indicated in the drawing. Electric heating elements 23 are used between solid and liquid fuels between protons.

The pipe 3 supply coolant is equipped with a cleaning filter 24, Figure 1, and a circulation pump for coolant 25, Figure 1.

The pipe 4 of the coolant outlet to the heating system is equipped with a thermometer 26, Figure 1, and a safety valve 27.

The housing 1 has a chimney 28, Figure 1, with a rotary plug - gate 29.

The device operates as follows. The coolant is poured into the water jacket 2, the electric heaters 23, the circulation pump 25, the boost fan 20 and the automatic fuel supply 17 are connected. Then the tank 15 is filled with liquid fuel, the combustion chamber 5 is loaded with solid fuel. Then 16 parts of liquid fuel are cast using manual fuel supply within 100 g. on under 19, turn on the boost fan 20. Next, set fire to the liquid fuel. 3-5 minutes after the start of stable combustion of liquid fuel, the automatic supply of liquid fuel 17 is drip. In the combustion chamber 5, pre-loaded with solid fuel, it ignites under the influence of ascending hot gases from hot liquid fuel on the hearth 19 of the chamber 21.

The advantages of the proposed device: the ability to use long firewood, because the length of the combustion chamber is equal to the entire length of the boiler; the possibility of using cheap liquid fuel, for example, used oil, because this fuel burns simply on the bottom of the combustion chamber without nozzles; the ability to cook and warm water, as the device above the combustion chamber has a working surface in the form of a cast iron plate with hobs; the ability to quickly ignite the boiler by using liquid fuel as an igniter; ease of maintenance of the device, as no removable replaceable parts for burning liquid fuel; no need to clean the grate, because slag from the combustion chamber enters the ash pan through the grate made of pipes of a round geometric shape; the possibility of using contaminated spent oil or heavy oil fractions as liquid fuel, as liquid fuel is simply poured on under the combustion chambers and burned without the use of nozzles.

An example of a specific implementation. The width of the boiler body is from 500 to 800 mm, with attachments - from 700 to 1000 mm. The height of the device is 600-1000 mm, length - 700-1200 mm. The boiler body is made of sheet steel 2-5 mm thick, the width of the water jacket is 20-60 mm. The number of electric heaters is from 1 to 4, with a capacity of 1 to 3 kW. The tank for liquid fuel is made of sheet steel with a volume of 3-10 liters. The grate of the combustion chamber and one of the side walls are made of steel pipes with a diameter of 15-30 mm. The charge air duct is made of a steel pipe with a diameter of 20-80 mm. The chimney has dimensions from 200 × 200 mm to 300 × 300 mm. The gate is made of sheet steel 3-5 mm thick.
