Description

The utility model relates to the furnace industry, namely, to the designs of furnaces for burning solid fuel and can be used in heating furnaces, water heaters, potbelly stoves, fireplaces, barbecues.

For ignition of furnaces for heating and hot water supply, containing a metal case, a combustion chamber with a door, an ash drawer, a chimney (AKTV-Karakan heating apparatus. Passport and instruction manual), independent means are used for igniting and fanning the fire, such as as a solid ignitor, liquid combustibles, blowtorch (RF Patent No. 2380617).

It is known that in order to ignite solid fuel and or to inflate fire, for example, coal, an ignitor must be installed in the middle of the ignition site, for example, a solid igniter soaked with kerosene, oil products or n-paraffin, place solid fuel around it and ignite the igniter with long match. After the igniter burns out, first a little smoldering is usually inflated with a blower, such as a hair dryer, until a flame of the required size is obtained.

Instead of using a solid igniter, it is known to use liquid denatured alcohol or other flammable liquid, which is sprayed over the ignition site and then ignited, followed by inflating the fire using an air blower.

The disadvantage of using a solid igniter or liquid igniter is that, firstly, there is a significant risk of burns during ignition of the igniter using a match or a lighter, and secondly, handling a solid igniter is unpleasant, since its smell remains on your hands, and thirdly Handling liquid means of ignition of a fire that is sprayed above the ignition site from a container is very dangerous; fourthly, due to the high temperatures of the blown fire, damage to the blower nozzle is formed on the hair dryer often used for this purpose.

An alternative to resolving the above problem is to use a blowtorch to light and inflate the fire.

Such a blowtorch is known, for example, from US Pat. No. 4,938,686. A blowtorch mainly includes a burner in which a gas-air mixture is produced by means of a nozzle distributor needle. If the nozzle of the nozzle is open, gas constantly passes through the burner, regardless of whether the blowtorch is in the hands or not. To stop the flame, the needle of the nozzle distributor must be completely closed.

The disadvantage of such a lamp is the high price of a gas blowtorch, its complex and sensitive to interference mechanics of flame adjustment, its constant, creating a high risk of burns, work, even if it is not in the hands, as well as the relatively large gas cylinder from which it works. This makes its use for non-professionals who have no experience with a blowtorch, uneconomical, complex and dangerous.

In addition, a lighter is known, consisting of a small container containing combustible gas, on one side of which a quick-acting valve with a built-in spark plug is connected, and on the other hand an elongated pipe with a nozzle at the output free end is installed. However, the lighter container holds a small amount of gas, and the tube has a length of about 5 cm, and therefore the lighter is only suitable for igniting a small, quickly flammable burner, such as a gas burner of a gas stove, or a candle. A small, flammable burner, such as a gas stove gas burner, or a candle.

All of the above means for igniting and inflating a fire are united by a danger in operation due to the high probability of burns and toxicity of harmful substances, as well as inconvenience of operation due to a long ignition time and the availability of improvised means.

The objective of the utility model is to create an effective ignition of solid fuel in time with ease of use.

This object is achieved in that in a furnace for heating and hot water supply, comprising a metal casing, a combustion chamber with a door, an ash drawer, a chimney, according to a utility model, a device for igniting and inflating a solid fuel fire is rigidly installed in the side or back wall of the metal casing of the furnace , which consists of a cylindrical metal casing, inside of which there is an electric heater, consisting of a spiral located in the channels of the ceramic insulator and whose ends brought outside the body of the device for ignition to connect them to the power supply; a cone-shaped nozzle is installed at one end of the ignition device housing, and a fan is built-in at the other end thereof, the ignition device being located at an angle to the grate and directed to solid fuel.

Figure 1 shows a General view of the furnace in section;

In Fig.2 - device for ignition in section.

The furnace for heating and hot water supply contains a metal housing 1, a combustion chamber 2 with a grate 3 and a metal door 4, an ash drawer 5, a chimney 6 (Fig. 1). A device for igniting solid fuel and kindling fire I (Fig. 2) is rigidly installed in the side or back wall of the furnace body, consisting of a metal housing of cylindrical shape 7, inside of which there is an electric heater 8, consisting of a spiral located at one end of the body of the ignition device a nozzle 11 of a conical shape, which can be made of metal or ceramic. At the other end of the housing of the ignition device, a fan 12, for example, of an axial type, is integrated. The device for ignition is located at an angle to the grate 3 and is directed by the nozzle to solid fuel 13.

The ignition of fuel in the furnace is as follows:

The furnace is loaded with solid fuel, for example, coal.

They apply voltage to the heater and fan, for example, from the mains. The jet of hot air emerging from the nozzle due to the heated coil and continuous air supply through the fan, which provides oxygen to the combustion zone, allows both to kindle and inflate the fire in the combustion zone. In this case, the required combustion temperature of coal is achieved within 2-3 minutes.

The advantages of the claimed utility model in comparison with the known are:

- ease of use due to the stationarity of the device for ignition and fanning the fire directly in the furnace and the minimum time for ignition;

- safety in operation due to the absence of harmful and toxic substances for ignition and eliminating the risk of burns to the user;

- the exclusion of places of storage of harmful substances for ignition;

- cost reduction due to the exclusion of additional substances for ignition.
