Abstract
A method for evaluating a quasi-stationary pressure difference detectable by a sensor at a gas boiler. The gas boiler has a mixing device (), a fan (), a main flow regulator (), a control valve () and a safety valve (). The sensor detects a differential pressure between a pressure (p) at a measuring point upstream of the main flow regulator () and downstream of the control valve () and a reference pressure (p, p) at a reference measuring point. The sensor transmits a signal to an electronic evaluation system. The electronic evaluation system compares the differential pressure during a pre-purge phase, wherein the safety valve () is closed, with the differential pressure after the pre-purge phase and detects an error by the comparison.
