Description

Es ist bekannt, staubförmigem Brennstoff wasserstoffhaltige Gase (Schwelgase, Generatorgase) zuzusetzen, um den Brennstoff mit diesen Gasen dem Verbrennungsraum zuzuführen und eine bessere Verbrennung zu erzielen. Zwar fand hierbei auch eine Absorption des Wasserstoffes durch den Brennstoff statt, doch ist das Maß dieser Absorption mit Rücksicht auf den verhältnismäßig geringen Gehalt dieser Gase an Wasserstoff unerheblich.It is known that pulverized fuel contains hydrogen-containing gases (carbonization gases, generator gases) add to feed the fuel with these gases to the combustion chamber and better combustion achieve. It is true that the hydrogen was also absorbed by the fuel instead, but the extent of this absorption is given in view of the comparatively low hydrogen content of these gases irrelevant.

Die Erfindung betrifft ein Verfahren zur Vorbehandlung von staiubförmigem Brennstoff zum Zwecke der Verhinderung der Selbstzündung des Brennstoffes beim Hinzutreten von Sauerstoff. Dies wird gemäß der Erfindung dadurch erreicht, daß der Brennstoff vor der Verbrennung mit handelsreinem Wasserstoff in zu diesem Zwecke ausreichenden Mengen zum Aufsaugen in Berührung gebracht wird. Der handelsreine Wasserstoff wird durch den Brennstoff in hohem Maße (bis zu etwa 2 Gewichtsprozenten) absorbiert, so daß auf diese Weise tatsächlich die Selbstzündung verhütet werden kann, während diese Wirkung bei der bekannten Zuführung des Brennstoffes zum Verbrennungsraum mittels Schwelgases oder Generatorgases aus dem oben angegebenen Grunde auch als Nebenwirkung nicht erzielt wird.The invention relates to a method for pretreating dust-like fuel for the purpose of preventing the fuel from spontaneously igniting when oxygen is added. This is done according to the invention achieved in that the fuel prior to combustion with commercially pure Hydrogen is brought into contact with suction in sufficient quantities for this purpose. The commercial grade hydrogen is absorbed by the fuel to a large extent (up to about 2 percent by weight), so in this way actually Auto-ignition can be prevented while this effect is known Supply of fuel to the combustion chamber by means of carbonization gas or generator gas is also not achieved as a side effect for the reason given above.

Die Vorbehandlung des Brennstoffes erfolgt zweckmäßig durch Zuführung des Brennstoffes zum Verbrennungsraum mittels handelsreinen Wasserstoffes, wobei dem in dieser Weise vorbehandelten Wasserstoff zwecks Beschleunigung der Verbrennung vor der Verbrennung vorteilhaft noch handelsreiner Sauerstoff zugeführt wird, ohne daß die Gefahr einer vorzeitigen Zündung besteht. The pretreatment of the fuel is expediently carried out by adding the Fuel to the combustion chamber by means of commercially pure hydrogen, whereby the in Hydrogen pretreated in this way in order to accelerate the combustion the combustion is advantageously supplied with commercially pure oxygen without there is a risk of premature ignition.
