What type of safety valve should be used in a micro-negative pressure furnace
Thread Content
The furnace operates normally, with the flue gas being drawn away by an exhaust fan (the flue gas contains complex components including a large amount of dust). Under normal conditions, the furnace is at a slight negative pressure. The purpose of installing a safety valve is to provide a safety measure in case the flue gas ducts become blocked, resulting in poor flow or even a complete blockage, thereby preventing accidents. However, the opening pressure of the safety valve under such conditions is not high, around 10–30 KPa. Please discuss what type of safety valve or safety measures should be used
Furnaces with a slight negative pressure generally have several safety doors, which are rotary covers that operate based on their own weight.
Several flip-type safety doors are installed, which are activated by cylinders along with counterweights. Pressure sensors are placed inside the furnace; when the pressure reaches a set value, the safety doors open automatically to allow exhaust and pressure release.
It contains a large amount of dust; what kind of furnace is this for, with such a modification? This is very important
In the form of explosion-proof discs or doors, it is difficult to select a safety valve based on the process conditions you mentioned
