Endlich ist es möglich, dem Brennstoff vor der Vergasung Kalziumverbindungen zuzusetzen.
Dieser Zusatz wirkt dadurch erhöhend auf die Ammoniakausbeute, dass er btickstoffhaltige Verbindungen unter Freiwerden von Ammoniak zersetzt oder die Zersetzung des Wasserdampfes unter Bildung chemisch wirksamen Wasserstoffes (in statu nascendi) befördert.
Auf der Zeichnung ist ein Ausführungsbeispiel eines für das "erfahren bestimmten Generators dargestellt. Der Generator hat zwei Zonen 1 und II, welche in der beschriebenen Weise abwechselnd mit Dampf und Luft behandelt werden. Die Grenzen der Zonen sind durch strichpunktierte Linien angedeutet. Der Generator a wird durch eine Bes@@@kungsvorrichtung b mit Brennstoff versorgt. Er hat eine Anzahl von Düsen c und d mit angeschlossenen Leitungen e und f, durch welche abwechselnd Dampf oder Luft zugeführt wird. Das erzeugte Gas entweicht

Zunächst werden die beiden Zonen 1 und II mit Luft angeblasen, bis die ganze Beschickung gluh Dann bläst man durch die Düsen c an Stelle der Luft Dampf in die obere Zone II ein, wahrend die Luftzufuhr in der unteren Zone I fortdauert. Die Zone II erzeugt also jetzt Wasser-

dationsp @@@@ e can be shortened considerably, at the same time a nitrogen-poor, rich gas is produced. '' Other gases can be added to eliminate them, e.g. B. exhaust gases from ammonia factories odt. u to regenerate them, e.g. B. Combustion gases.
It is finally possible to add calcium compounds to the fuel before gasification.
This addition increases the ammonia yield by decomposing nitrogenous compounds with the release of ammonia or by promoting the decomposition of water vapor with the formation of chemically active hydrogen (in statu nascendi).
The drawing shows an exemplary embodiment of a generator intended for the "experienced". The generator has two zones 1 and II, which are treated alternately with steam and air in the manner described. The boundaries of the zones are indicated by dot-dash lines. The generator a is supplied with fuel by a filling device B. It has a number of nozzles c and d with connected lines e and f, through which steam or air is alternately fed in. The gas produced escapes

At the bottom of the generator there is a hood i for discharging the ash, which is cooled by small amounts of steam blown in. In an emergency this hood can also be used for feeding

First, the two zones 1 and II are blown with air until the entire charge is glowing.Then, instead of air, steam is blown into the upper zone II through the nozzles c, while the air supply in the lower zone I continues. Zone II is now generating water

Generated temperature generator gas. As soon as the nitrogen content of the fuel surface in Zne II is used up, air is passed through the nozzles c into zone II, while steam is now fed to zone I through the nozzles d, so that water gas and ammomak are now produced.
(Zone II, on the other hand, supplies generator gas. The gases withdraw together through the openings g 111 he main line / t.
