Description

Incandescent light burner for liquid fuel. The invention relates to a suction wick incandescent light burner for liquid fuel, in which the heat of the Return rod through part of the mixing device, the mixing head, onto the Evaporator is transferred, with the nozzle and the mixing tube on the side of the mixing head are arranged.

Burners of this type are known, for example from the German Patent 44526. According to the principle of this device, the fuel is evaporated inside the sucking wick, in such a way that one with the mixing head thermally connected, special but empty evaporator, reaching down into the wick tube, is embedded in the middle of the wick in order to generate the burning steam here and through a side line and a cross-mounted mixing tube with the heat return rod feed connected mixing head. In this case, the should be returned to the evaporator Heat does not extend to the wick tube connected to it, which is why the connection of the two parts is made of a material that conducts heat poorly.

In contrast to this principle, according to the present innovation Wick tube and mixing head are connected in a way that conducts heat to the heat of the mixing head seated return rod to concentrate on the wick tube and the evaporation of the fuel on the wick circumference. Here the steam pipe goes from the wick pipe off, while nozzle and mixing tube are attached according to the older facility are.

The advantage of the innovation lies on the one hand in the simple construction itself and on the other hand in the reliable cooperation of the whole by the fact that the If the wick tube forms an evenly free space up to the mixing head, it can be the tried and tested Get wool wick, which ensures a backward escape of burning fumes prevents and causes that at the evaporation point for efficient operation the overpressure required by the burner is created. Furthermore, the new construction allows a very close moving of the heat return rod and wick tube or evaporator, whereby the path of the return heat to the latter is so considerably shortened that the loss of heat to the outside is insignificant. As a result, building the Brenner's material with a lower thermal conductivity than copper can be used.

In the drawing, a burner according to the present innovation is through Fig. I in longitudinal section and Fig. 2 in cross section along line a-b of the longitudinal illustration shown.

a is the wick tube and b the wick with which it is filled. The steam line c extends from the upper end of the tube and ends in the nozzle e through which the steam is blown into the transverse mixing tube g. The steam mixed with air then passes into the mixing head f, through which it is bent upwards; a semicircular kettle f 1 facilitates this process. The mixture then flows through the holes h in the mixing head plate (Fig. 2), to which the heat return rod i is connected. The mixture then enters the burner head k and through the distribution screen, passes the burner head shower n and reaches the incandescent body o for combustion. The steam line leading to the burner is opened or closed by a spindle d.
