Operating device for a high-power surface burner and operating method for same

摘要

The surface burner (3) is supplied with air through lines (8, 6) to and from the blower (5). The gas pressure regulator (9) controls the pressure in the line (7) and is operated by an actuator (10) having a control input (25) connected to a solenoid valve (26). During ignition, this sends a pressure signal to the control input, causing enrichment of the mixture supplied to the burner. The control input alters the pressure reference value controlled by the regulator (9). The regulator sets the gas pressure to a first value for operation of the burner. It sets the pressure to a second value for ignition. An independent claim IS INCLUDED FOR the corresponding method of ignition of a high power surface burner.
