Description

Description too Low-voltage ignition device for heating oil stoves and the like over the power grid.

The oil stoves on the market up to now become predominant set in motion with a match, wick or kindling paper. There must be the burning Paper is usually thrown into the oven from above, first taking the pilot's ring and then must pass the burner ring before it falls on the oil. So you have to With a little skill you can throw the burning object into the oven so that it can be goes well. Lighting this modern stove is therefore still old-fashioned, cumbersome and time consuming.

This is where the present novelty helps.

As a novelty, a low-current glow cartridge is used as a permanent cartridge used for ignition via a switch, for example a short-time switch and a transformer is connected directly to the lighting network and has a voltage of approx. 12 volts is working.

The permanent cartridge can be used with both a heating wire and even with a heating element both one-pole and two-pole. The structure of the Permanent cartridge is as follows: In a metal body, an insulating insert z. B. Mica, porcelain, or the like and in this is insulated from the metal body, the heat-resistant heating wire made of a special alloy respectively. Heating rod - hereinafter only referred to as heating wire - embedded. The poles are thus completely stripped from the furnace. This heating wire now protrudes from the front End of the permanent cartridge angled out in a relatively great length. Novelty this bending of the heating wire is of particular importance for the assembly. It was found in the many tests carried out that with the angled Heating wire the correct position of the lower end of the heating wire in relation to the oil bath in the combustion chamber can be set individually in the simplest way by turning accordingly can do what is necessary, given the height of the oil level in the combustion chamber at each Furnace is different.

The lighting of the oil is based on the novelty that on the form beads immersed in the oil and brought to the annealing temperature, which rise up on the heating wire, burst and form a fine oil vapor (¢ mist), which is now on the part of the glowing heating wire that is outside the oil ignited.

Due to the many experiments that were carried out, this Ignition process further refined by the fact that one with a hole on the combustion chamber floor provided insert made of asbestos fabric is placed. This lies with its underside in the oil and soaks up like a wick. In the hole now arises from the very rapid Distribution of the oil in the highly absorbent asbestos immediately creates an oil mist into it the end of the heating wire protrudes. This oil mist, which is practically always present, ignites immediately on the glowing heating wire.

The new use of asbestos fabric made it a success Much more effective because the ignition process is now faster and safer going on.

As soon as the oil continues to burn by itself, the glow cartridge can be switched off. The heating-up process is finished. According to the novelty, the low-voltage glow cartridge can be used in the combustion chamber can be installed horizontally or at an angle the.

There have been many attempts with good and bad pulling furnace systems carried out. It was found that the novelty is absolutely insensitive to the problem and that it ignites equally well in a cold as in a warm stove. The primary side of the transformer is connected to the mains and by hand, timer, thermostat or any other known type of switch-on device can be switched on.

On the attached drawing is the novelty with a two-pole Heating wire shown schematically as an example and installed in an oil furnace.

Figure 1 shows a vertical section through the oil furnace with horizontal built-in low-voltage glow cartridge.

Fig. 2 shows a section of the combustion chamber with optionally angled built-in low-voltage glow cartridge.

1 is the oil furnace jacket, 2 is the combustion chamber, 3 is the burner ring, 4 is the Pilot ring and 5 the throttle trigger.

6 is the bent filament (glow rod), 7 is the insulating body made of mica or porcelain. 8 is the jacket of the glow cartridge and 9 is a nut for the Tighten the glow cartridge on the combustion chamber wall. 10 and 11 are terminals for the two-pole heating wire, 12 is an intermediate ring made of insulating material.

13 is a transformer and 14 is a switch. 15 is a sealing washer, 16 the asbestos fabric insert with the breast hole 17, 18 is the inlet pipe for the Oil and 19 the oil in the combustion chamber. Parts 6-12 form the low-voltage glow cartridge.
