• KLASSE 10: Brennstoffe. • CLASS 10: Fuels.
Holzkohle, namentlich wie sie zur Heizung von Eisenbahncoupds in Form von Briquettes dient, erhält bisher, um sie entzündlicher und leicht brennbar zu machen, gewöhnlich einen Zusatz von salpetersaurem Kali oder Natron.Charcoal, especially as it is used to heat train coupds in the form of briquettes used to make it more flammable and easily combustible, usually received one Addition of nitric acid potash or baking soda.
Da diese sich während der Verbrennung in kohlensaure Salze umwandeln, so wird der Aschengehalt eines solchen Brennmaterials sehr gesteigert, und zwar oft bis zu 12 pCt., und dadurch wiederum die Brennbarkeit und Entzündlichkeit der Kohle vermindert, was durch vermehrten Zusatz obiger Substanzen ausge-. glichen werden mufs. Dies macht aber solche Kohlen sehr theuer.Since these are converted into carbonic acid salts during combustion, the Ash content of such fuel is greatly increased, often up to 12 pCt., And this in turn reduces the combustibility and flammability of the coal, which is due to increased addition of the above substances. must be resembled. But this makes such Coals very expensive.
Weit billiger und besser lassen sich Kohlen leicht entzündlich und leicht brennbar machen, wenn sie, je nach dem Grade der Entzündlichkeit und Brennbarkeit, den man erreichen will, mit Salpetersäure getränkt werden. Es ist hierzu nur ein sehr geringer Procentsatz der letzteren nöthig. Dieselbe verbindet sich mit den Aschenbasen, indem sie deren Säuren austreibt.Coals can be made easily ignitable and easily combustible by far cheaper and better, when they reach, according to the degree of flammability and flammability one reaches wants to be soaked in nitric acid. There is only a very small percentage of this the latter necessary. It combines with the ash bases by driving out their acids.
Durch einen solchen Zusatz wird eine Vermehrung des. Aschengehalts nicht bewirkt. Such an addition does not increase the ash content.
