Technical Field

[0001] The utility model relates to the technical field of boiler flame monitoring, in particular to an observation device for boiler flame monitoring. Background Art

[0002] A boiler is a device that uses the heat energy released by fuel combustion or other heat energy to heat working water or other fluids to certain parameters. In order to facilitate the control of the boiler flame conditions, an observation device is usually installed on the boiler to facilitate the observation of the flame.

[0003] Currently, the commonly used observation device is a glass window with a scraper. During use, the scraper can be rotated by turning the crank set in the middle of the glass window to clean the dust and dirt on the inside of the glass window. However, in this way, the inside of the glass window is exposed to the furnace, which will cause the glass window to be continuously eroded by dust and dirt, affecting the transparency and visual quality of the glass window, thereby causing the clarity of the glass window to gradually deteriorate, affecting the monitoring work. Therefore, the technical personnel in this field provide an observation device for boiler flame monitoring to solve the problems raised in the above background technology. Utility Model Content
