D u r c Ii 1 a u f v e r d a m p f e r

for Ö 1 b r e n n e r oleic oil vaporizer or oleic oil gasifier-whether Liit or without electr.

Electricity has not become known in Europe.

The efforts of the burner manufacturers show a great tendency through refinements of the iciz technique, the same oil consumption under control obtainable, for example through oil preheaters, air flaps, etc.

The invention described below according to sheet 6 has as an alternative The task of converting the heating oil into gas in front of the burner nozzle, with sufficient Mix the air and burn it completely. An environmentally friendly incineration of heating oil can be achieved with this new heating technology, with enormous savings of the very expensive heating oil is achieved.

To prevent the heating oil evaporator from being sprayed with heating oil the Heizölzuflußröhr as well as the hot gas discharge pipe arranged outside of the flame tube and opens into the two arms of the nozzle stock, the heating oil supply pipe being one Has a smaller cross-section and the gas discharge pipe to a larger cross-section is reamed.

To ensure that the heating oil evaporator pipe is heated up quickly, the same is coiled several times, so that a large tube surface as a heat exchanger is available. Furthermore, the heating oil evaporator tube is equipped with ceramic or fireclay rings enveloped in order to prevent coking of the same. In addition, these chamotte rings are profitable a high build-up of heat, which means that when the heating burner is switched on again, a rapid Evaporation of the heating oil is guaranteed.

By evaporating the fuel oil according to this invention, it is possible reduce the oil pressure of the oil pump, but this requires an increase in the Oil nozzle by about 25 - 30%; the burner noise drops considerably, which is very beneficial affects.

As can be seen on sheet 5, the evaporator tube can have a larger one Have internal cross-section, with a multi-wire copper cord inserted as a reduction which also serves as a heat exchanger and quick evaporator of the heating oil. A fine-wire copper cord is provided for the heating oil inflow and for the gas outflow a coarse-wire copper cord, which has 50% more flow than the oil inlet side. To get the start-up phase under control when the oil pressure is low, an electric operated heating oil gasifier upstream of the nozzle assembly, which the heating oil on 180 ° heated and remains switched on until the flame-heated fuel oil evaporator is hot enough to continue gasifying the fuel oil. The electric one The fuel oil gasifier switches off automatically. As soon as the heat sensor shows 1800, the temperature goes back to 1600 and then the electr. Fuel oil gasifier on again, so that from the beginning. of switching on the burner to the end the heating season, the oil gas can be heated at any time.

The electric fuel oil gasifier is designed so that it does not have any Coking by heating oil suffers, in addition, the same switches after about 30 seconds automatically off.

A safety valve for the electr. Heating oil gasifier is provided.

Sheet 1 shows a once-through evaporator with a ring evaporator tube sheet 2 shows a once-through evaporator with a multiple coiled horizontal evaporator tube Sheet 3 shows a once-through evaporator he more multiple coiled vertical evaporator tube Sheet 4 shows a continuous flow evaporator with inserted copper cord sheet 5 shows a continuous evaporator he shows sheet 6 with coarse and fine copper cord a once-through evaporator with a coiled one arranged outside the flame tube Evaporator tube with ceramic or fireclay rings. Sheet 7 shows a once-through evaporator As Fig. 6, but with an enclosed copper cable in the inner cavity of the evaporator tube Sheet 8 shows a once-through evaporator with a ceramic insert and one inside of the flame tube arranged evaporator tube, but with opposite bulges for the evaporator tube and in the lower part of the flame tube a second flame tube piece, which covers the bulge in the main flame tube.

Sheet 9 shows the top view of the main flame tube with its bulges and the lower drawing shows the top view of the ceramic insert sleeve, which is provided once to protect the steam pipe and as a heat store is.

G e c h n i n g e d e c o f p e rtio n of the once-through evaporator for oil burners The heating oil evaporator to be described here (sheet 6) consists of one Nozzle holder (1) with two lateral square-shaped arms (13), which on the right and protrude on the left over the split flame tube (17. + 18) and receiving holes for the evaporator tube (11).

The nozzle assembly (1) has its boreholes (4) gas outlet and borehole (5) Heating oil inlet moved into the boom, whereby the oil inlet side (5) is weaker is dimensioned as the gas outlet side (4).

The heating oil evaporator tubes (4 + 5) are outside the two nested ones Arranged flame tubes. It has been shown that the evaporator tubes (11) at sheet 1 - 5, which are arranged inside the flame tube, sprayed by heating oil vapor and the oil drips into the burner space, creating soot.

The tests have also shown that the heating oil evaporator (11) also absorbs heating oil through the spray oil and outside during prolonged operation coked This is remedied by slipping the fireclay rings (12) over the Coiled evaporator tube, so that the fuel oil sprayed onto the hot chamotte rings (12) evaporates.

By connecting an electr. Fuel oil gasifier (16), which in The heating oil gasifies for about 20 seconds and the heating oil evaporator (11) is heated until that it continues to gasify the heating oil on its own, whereby the heat sensor ( 15) at 180 ° oils. the electr. The heating oil gasifier (16) switches off automatically.

A large filter (2) in the nozzle assembly (1) prevents clogging the burner nozzle (8). A safety valve (1 4) is in the feed arm (13 ) arranged.

ie sheet 4 shows, is in the cavity of the evaporator tube (5) and (II) a multi-wire copper cord inserted, which is an excellent heat exchanger works and causes rapid evaporation of the egg oil flowing through it.

On sheet 6 it can be seen that the evaporator tube (5) is a pipe connection (19) with the coiled evaporator tube (II), which is used to produce the coiled To clean the evaporator tube (II) or a light one if it is damaged To enable replacement.

Through the outside of the split flame tube (I7 and I8) Evaporator tubes (5) it is necessary that the flame tube consists of two split flame tubes (I7 and I8), which are provided with joints and over the nozzle.

head extensions (13 and 14) can be pushed telescopically over one another, at least part of the flame tube (I7 and I8) being displaced towards the nozzle assembly (I) can be.

In the embodiment according to sheet 8, the gasifier tube is a continuous flow (5) provided with a ceramic sleeve (20), the front part of the ceramic sleeve (20) is circular, which creates a heat accumulator and In addition, the flow-through carburetor pipe (5) is protected against corrosion.

The circular ceramic sleeve (20) is with annular Ausneh-.

provided (21), which allow the heating flames to flow through, straight webs (22) being provided for the stability of the circular ceramic sleeve are. The circular webs (23) are several centimeters deep and are wedge-shaped formed so that the microdroplets flowing out of the nozzle well onto the heated can hit circular webs (23) and gasify at lightning speed.

The flame tube (17) has two recesses (24) opposite one another which the flow-through carburetor tube (5) is embedded, a second tube sleeve (25), which is inserted in the lower part of the flame tube (5), covers the recesses (24).
