Abstract

Der Brenner ist an eine Brennstoffleitung (5) angeschlossen und dient zur Beheizung eines Heizkessels. Die Regelanordnung umfaßt einen Temperatursensor (2) zum Erfassen der Kesseltemperatur, wobei der Sensor sowohl an ein Regelglied (1) als auch an ein Sicherheitsschaltglied (6) angeschlossen ist. Regelglied und Sicherheitsschaltglied stehen mit einem Stellglied (3) in Verbindung, welches ein in der Brennstoffleitung (5) angeordnetes Ventil (4) betätigt. Das Regelglied (1) dient dazu, die Kesseltemperatur auf dem vorgegebenen Wert zu halten, während das Sicherheitsschaltglied eine Sicherheitsabschaltung der Brennstoffzufuhr bei Überschreiten einer vorgegebenen Höchsttemperatur bewirkt. Regelglied und Sicherheitsschaltglied werden von ein und demselben fehlersicheren Temperatursensor (2) versorgt.

Figure 00000001
The burner is connected to a fuel line (5) and is used to heat a boiler. The control arrangement comprises a temperature sensor (2) for detecting the boiler temperature, the sensor being connected to both a control element (1) and a safety switching element (6). The control element and the safety switching element are connected to an actuator (3) which actuates a valve (4) arranged in the fuel line (5). The control element (1) serves to keep the boiler temperature at the predetermined value, while the safety switching element causes the fuel supply to be switched off safely when a predetermined maximum temperature is exceeded. The control element and the safety switching element are supplied by one and the same fail-safe temperature sensor (2).
