RIECO provided Fume Extraction System with spark arrestor to arrest the immediate spark coming out of the fumes. Rieco provided an efficient pulse jet online bag filter with centrifugal fan and a double – line bag house with Motorized Swivelling mechanism which would move the hood during the hot metal pouring operation.
The above system eliminated hazardous fumes completely and ensured that the workers can work in a safe environment.
The Fume Extraction System consists of the Following:
For Double line Offline Bag House
For Pulse Jet Online Bag Filter
ressure Drop across Baghouse: 150 mmWC Max.
The fumes from tap hole & ladle will get sucked into the baghouse via spark arrestor to avoid any spark going into the baghouse, which could damage the filter bags.
The necessary negative pressure required for effective suction of fumes will be generated by a backward curved Induced Draft (ID) fan.
The swivelling hood at the ladle area is moved over the ladle with the help of a forward & reverse starter and when the pouring operation is completed, it is moved back to the parking position. This operation of moving the swivelling hood is very easy and convenient for the workers working in the blast furnace area.
All the Dust particles in the fumes are captured in the Baghouse with 99.9% efficiency and the outlet emission at stack is just 30 mg/Nm3, which cannot even be seen with the naked eyes.
