Damit man zur Erhitzung der Silikate mit Anunoniumkarbonat nicht beschere Heizungsanlagen und besondere Brennstoffe zu verwenden hat, werden die aus den Kalk- öfen kommenden Rauchgase verwendet, deren Wärme für diesen Zweck vollkommen genügt, weil Ammoniumkarbonat schon bei 10000 die erforderliche Spannung von ungefähr 10 bis 12 item. erreicht.
Werden die Silikate noch vor der Behandlung mit Ammoniumkarbonat mit Kalk gebrannt, so enthalten sie alle der Zusammensetzung des Portlandzementes entsprechende Bestandteile, wodurch es ermöglicht ist, die derart aufgeschlossenen und von den Alkalien befreiten Silikate durch neuerliche Erhitzung zu Portlandzement zu brennen.

So that one does not have to use heating systems and special fuels to heat the silicates with ammonium carbonate, the flue gases coming from the lime kilns are used, the heat of which is completely sufficient for this purpose, because ammonium carbonate already has the required voltage of about 10 to 12 at 10,000 item. reached.
If the silicates are burned with lime before the treatment with ammonium carbonate, then they contain all the components corresponding to the composition of the Portland cement, which makes it possible to burn the silicates that have been broken down and freed from the alkalis to Portland cement by heating them again.
