E&G Graetzin 915
outdoor alcohol lamp

From an old study done by dr. H. Lahde we can learn how the lamp works.
The fuel used is alcohol (spiritus).
Amount of light output is +/- 100cp

On the left step 1.
The key is turned all the way to the right.
A tube fills until the level is the same as in the pressureless tank.

Step 2:
The key is turned to the left.
The first filled tube is emptied in the pre heater ring. At the same time the generator is filled over a filter gauze.

Step 3:
The key is still in the left position.
The filled generator starts to vaporize and gas is pressed, by the liquid fuel underneith, into a gas dome and then downwards to the nozzle, where it is mixed with air from outside and ingnited by the still burning pre heater ring.
