Black smoke is coming from the aluminum silicate insulation material of the equipment
Thread Content
The insulation material inside the tank is composite aluminum silicate. The oil used for stirring in the tank is No. 32 white oil; when the workers added this oil, some of it accidentally leaked into the insulation material. 10 kilograms of steam were supplied through pipes surrounding the tank, and during a routine inspection, it was observed that black smoke was continuously coming from the insulation material of the tank. Can it be determined that the white oil has been carbonized?
The insulation material contaminated with materials must be completely replaced. Carbonization is a minor issue; 10 kilograms of steam typically reaches a temperature of around 180°C, while the flash point of white oil is approximately 120°C. Moreover, the insulation layer of the reactor is already quite thick; accumulation of heat inside could lead to a dangerous flash explosion.
