Both the first and second members have an upper internal diameter of 100 to 150mm and a lower internal diameter of 170 to 300mm. The distance between opposing open ends of the first top member is 60 to 100mm. A top end (24, fig 2a) of the first member may be provided with a mesh member 23 to cover an opening in the top end. The second bottom member may comprise a plurality of struts (40, fig 3b) having a recess (46) to support the first member and maintain the first and second members in stacked spaced arrangement.

Title: Method for operating a failure protection device of a flame sensor
Inventor: PETER DODSON
IPC: F23N5/24
Filed: 2020-05-28
Abstract: A method 10 for operating a failure protection device (12 Fig.1) of a flame sensor (14 Fig.1) in which an optical sensor element 16 detects both a monitoring signal 18 and a signal indicative of the status of a flame (22 Fig.1), e.g. flame presence or flame absence. The method includes correlation between signals from both the monitoring signal and the flame status signal as detected by the optical sensor element, and the correlation indicates if the flame sensor is functioning properly. The signal from the optical sensor may be processed 44 and analysed 46 prior to evaluation 48, and the monitoring signal may be generated by a light emitter element 40 such as a light-emitting diode. The flame is fuelled by hydrogen or a fuel supply 32 with a substantial hydrogen content, and a control unit (28 Fig.1) may produce a control signal 50 to control the light emitter element. The control unit tries to detect the monitoring signal in the sensor signal, and if the control unit can detect the monitoring signal in the sensor signal, it indicates that the flame sensor is functioning properly. If the control unit cannot detect the monitoring signal in the sensor signal, it indicates that the flame sensor is not functioning properly, regardless of whether the optical sensor element or the emitter element is not functioning properly.
