Product Introduction:

DEK-FL/GL/800 (Ex) explosion-proof endoscope high-temperature camera (hereinafter referred to as "camera"). This product is strictly designed and manufactured in accordance with GB3836.1-2010 Explosive Atmospheres Part 1: General Requirements, GB3836.2-2010 Explosive Atmospheres Part 2: Equipment Protected by Explosion proof Enclosures "d", and GB12476-2000 standards. The camera is mainly applicable to industrial heating furnace, power plant combustion furnace, garbage combustion furnace and steel plant power furnace in the petrochemical industry. For oil, coal and gas furnaces, the camera lens can be directly inserted into the furnace, and the working state of the flame in the furnace can be continuously and real-time monitored in the central control room, so that the combustion nozzle and other objects in the furnace can be clearly observed. For the poor atomization of the nozzle in the furnace, the oil leakage causes unsmooth flame spraying, the flame becomes smaller, and the poor air distribution of the nozzle causes the flame to be too long, resulting in pipe licking phenomenon. The furnace tube deformation in the furnace, sintering and pipe bursting accidents can be monitored in real time and handled in a timely manner to prevent accidents in the furnace, ensure the reliability of the economic operation of the boiler furnace, and also facilitate the realization of centralization Automation of scheduling and production process. The system adopts PLC programmable control and has the function of automatic shutdown and over temperature exit protection.
