· Product use
In the operation of the thermal power plant unit, when the boiler sends air
The abnormal operation of the machine causes the furnace to be at too high induced air pressure
Head down at the same time due to rapid reduction in fuel input or total
Fuel trip (MFT) causes a sharp drop in furnace smoke and pressure
Low, this combination of harsh working conditions will cause the furnace to implode
(Suction deflated), installed on the boiler body and the front flue of the dust collector
Install a self-opening and closing negative pressure explosion-proof door, which can make the boiler implode
It can supply air to the boiler and flue in advance to avoid permanent deformation of the furnace and flue explosion.
· Product introduction
ZD-FBFX series self-opening negative pressure explosion-proof door is a new generation of negative pressure protection products developed by Lianyungang Huadong Electric Power Equipment Co., LTD. The device adopts magnetic automatic opening and closing technology, the operating pressure is accurate, the automatic reset after the operation, no need to stop. It is a new product to protect boiler body and flue from being sucked and deflated.
