Title: Process for operating a shaft kiln for burning limestone uses natural gas, heating oil or coal dust as fuel in two combustion periods
Inventor: SCHMIDT ADOLF
IPC: F27B1/00
Filed: 1998-09-24
Abstract: Process for operating a shaft kiln for burning limestone uses natural gas, heating oil or coal dust as fuel (BS) in two combustion periods. During the first combustion period, the fresh combustion air (Lp) in the preheating zone (VZA) of the shaft (A) is heated regeneratively countercurrently to 700-750o C. Only 60-70% of the total requirement for fuel is directly fed into the bulk material at the upper end of the combustion zone (BZA) of the shaft. Combustion in the combustion zone (BZA) of the shaft occurs stoichiometrically and the waste gases from the combustion zone enters the connecting channel (VK) at 900o C. 40-30% of the residual fuel (BSK) is fed to the bulk material to raise the waste gas temperature to 1250o C by combustion with the aid of cooling air (LK). The bulk material in the combustion zone of the further shaft (B) is deacidified countercurrently. The waste gas leaves the upper end of the combustion zone of the further shaft (B) at a temperature of over 900o C and flows through the preheating zone (VZB) of the shaft (B). These processes are repeated in a second combustion period.

Abstract: Es wird ein System in einem Verfahren zur sicheren Identifikation und Registrierung von Personen, insbesondere für die Herausgabe von personenbezogenen Berechtigungsmitteln wie einer digitalen Signaturkarte, angegeben. Die sichere Registrierung erfolgt in einem System, bestehend aus einem Berechtigungsherausgeber, zum Beispiel einem Trust Center, und wenigstens einer Registrierungsstelle, wobei Berechtigungsherausgeber und Registrierungsstelle in ein Authentifikationssystem eingebunden sind, das sicherstellt, daß nur von dem Berechtigungsherausgeber berechtigte Registrierungsstellen die Registrierung vornehmen können. Dies wird dadurch erreicht, daß personenbezogene Daten von einem die zu registrierende Person identifizierenden Dokument eingelesen werden, wobei das zu identifizierende Dokument wenigstens ein biometrisches Merkmal der Person enthält. Das von dem identifizierenden Dokument übernommene biometrische Merkmal wird auch vor Ort von der anwesenden Person übernommen beziehungsweise gemacht. Eine Verifikationseinheit vergleicht die unmittelbar vor Ort erfaßten Daten mit denen von dem identifizierenden Dokument erfaßten Daten und stellt mit einer gewissen Wahrscheinlichkeit fest, ob es sich bei der eine Registrierung nachsuchenden Person auch tatsächlich um die Person handelt, die sie vorgibt zu sein.
