The present invention relates to a method and jine Preparation of firings of any type with liquid «fuel.

In accordance with the state of technology, the use of τοη flUeaiges Fuel In such furnaces over burners · Thereby I divide the burners in alternate ways, namely the vaporization separators on the one hand and the pulverieation burners on the other hand.

The area of application of the taporieation burner is very limited, Aa ei · only for domestic installations with low fuel consumption are suitable and therefore not applicable in industry · Xn der Mehriahl der Te intend et aas so Pulverization burner

The operation of such devices consists of pulseration of the pulp in small droplets when it enters the furnace occurs · This fulTerloleruag is usually due to either • iM Ulf! Liquid (so-called »burner old help liquid«)

or by mechanical means (so-called "burner with mechanical FulTerization ") carried out" In any case, the goodness of the pulverization carried out »cs.h. the delicacy of the educated Droplets »a major factor in good operation ·

The invention relates to a new method and a new device for feeding τοη furnaces with liquid fuel , the principle of which means liquid fuel is applied in an electric field the quality that is obtained with conventional devicesj it is a real spray

D & 8 inventive demonstrations of charging τοη furnaces with liquid fuel consists in 3 & a liquid fuel containing ionized bonds in a laminar flow manner into a combustion chamber of a furnace »whereby it is subjected to an electrical high voltage at the same time & 9V effect» »field8, which is subjected to the immediate destruction of the fuel introduced into the combustion chamber of the furnace causes

The electric field that can be applied can either electrostatic or electromagnetic no.

On the other hand, the liquid fuel is preventive a pretreatment ionized, which consists in giving it a highly polar liquid, which then ionizes bonds In de * liquid fuel forms *

With such a device it can happen that the flame · the electric field at the outlet opening of the nozzle (or at the outlet openings of the nozzles), which of course the operation of the device interferes "

To remedy this disadvantage, the present invention relates also a modified form of the one shown above Method and an improved device for its execution

In particular, the invention also relates to an improved one Procedure »in which one has a cyclical, periodic drive doing the cracking and burning, with Jedt Perlode this operation a ZeroprUhungsphase through the Build-up of the high voltage electrical field and a combustion phase has, at ier the field is degraded tad during that the sprayed fuel is burned

As a precaution, the period of cyclical operation is very high kuri »for example in the order of magnitude of 0.02, and is distributed, for example, over an atomization phase of 0.012 seconds and a combustion phase of 0.008 seconds

The present invention also relates to a device sur Charging of furnaces with liquid fuel for the execution of the modified Porm des Verfahrene »at dtr at least one storage room for the fuel in lasinarexa FIuS flows out, i / Iittal »which in <? he level of the nozzle Build up strong electric field, ignition means that at least an electric spark inside the sprayed fuel «Linden, and funds are provided» die wechcelweie ·

Most of the existing liquid fuels are mixtures composed primarily of hydrocarbons and are dead ellem have equivalent ties

In general it is alao necessary »in a phase Tor dem Process in the liquid fuel to generate ionized bonds. Advantageously, these bonds are thereby This gives the liquid fuel a certain Amount of a strongly polar liquid added "

In the case of clay house brand oil, for example, you can add 2 to 5 4 » biketone alcohol» which leads to the formation of ionized bonds * these bonds are also permanent * and their number depends on the proportion of siketone alcohol in the mixture ·
