Abstract
The utility model relates to a flame detector of a combustor and especially to an ion flame detector of a combustor and belongs to mechanical technical field. The ion flame detector comprises a cylindrical housing. A ceramic insulator is disposed on the inner wall of the housing and is extended out of the housing upwardly. A sealing washer is arranged between the ceramic insulator and the top of the housing. A core rod is disposed in the ceramic insulator and is extended out of the ceramic insulator upwardly. An electrode disc is sleeved on a part, of the core rod, extended out of the ceramic insulator upwardly. The ion flame detector is characterized in that at least two electrode wires are installed on the electrode disc, and that platinum layers are disposed on the surfaces of the electrode wires. Therefore, an effect of high temperature and flue gas resistance is achieved and detection sensitivity is increased. The ion flame detector has beneficial effects of substantially enhancing the high temperature resistance of the ion flame detector and achieving an excellent insulating property.
