Description In the gas and oil burner heating, the feed from air to gas volume or air to oil volume through ##### various control devices supplied to the combustion in an assigned dosage in order to achieve the prescribed combustion values, that are subject to environmental protection. The relevant industry has this Devices brought out in two execution groups. One execution group is working very accurate and is complex and very expensive, the other execution group is cheaper, but it delivers combustion values that do not yet meet expectations.

In the case of cheap designs, rigid and flexible ones make do with them Curve guides. The flexible curve guides are made using steel strips and adjusting blocks generated. When set, the steel belts can also be viewed as rigid and can only reproduce those values that are taken from the curve can and generate only approximate optimal combustion values, which in turn adversely affect environmental protection regulations.

Mode of Operation of the Invention The following invention enables on easy way an optimal scheme that is environmentally friendly and values the above mentioned exact execution group provides.

The burner housing (14) are for the most part as cast parts executed. It is well known that castings are subject to certain tolerances, especially Die Sandgußteile0 If you select the air intake nozzle as the parameter for the burner control (1), every cross-section will have its inherent deviation. One drifts the air flap (2) of the air intake stub (1) by means of a drive motor (3), so a cross-section of the air intake duct becomes for each air flap position (1) Appropriate air flow allowed through.

The exact amount of fuel must now be fed into the air stream will. This can be achieved inexpensively with the following facility: Will A cylinder (5) is placed on the shaft (4) of the ventilation flap (2), on which a differential photo element (6) is attached, read off the curve (7) pushed on with a pencil and its control pulses via an amplifier (8) to the drive motor (9) of the gas or oil control (10) passes on, so that the optimally allocated amount of fuel to the Burner is supplied. The curve (7) can already be used in the factory of the burner manufacturer are provisionally registered to darln at the user's location by means of Eraser and pencil to be corrected so that an optimal mapping of Air to gas mixture or air to oil mixture is achieved. Will be different Fuels, a separate curve with its own can be used for each type of fuel Difference photo element (6) can be attached.

Another safeguard for the optimal setting of the facility will be Daurcll is achieved by placing between the cell (4), the air flap (2) and the cylinder (5) a membrane (11) built in, the fluctuation of the atmospheric air pressure counteracted and thus the amount of air adapts to the weather. Is the atmospheric one Air pressure is high, so the air supply must be throttled accordingly, it is on the other hand, the amount of air must be increased in a corresponding manner.

This adjustment is achieved automatically through the membrane (11). The membrane (11) can be mechanical, electro-mechanical.

or be designed electronically. The membrane (11) can by means of an adjusting screw (12), depending on the altitude of the burner installation site, adjusted accordingly.

The curve (7) can also be influenced in this way by means of a thermal sensor (is) be that with temperature fluctuations of the air in the atmosphere the necessary Dosing air-gas mixture etc. can be optimally set automatically.

If necessary, a hygrometer can be included in the system be that a certain dependence by the humidity, in relation to the Combustion values, can be compensated.

Has a big advantage over conventional Sus guides this invention that sio no tolerances of rods, ball joints and hooking mechan.

Is subject to curves and therefore always correct combustion requirements creates what can seldom be said about conventional systems.
