Abstract

Presentation location: Reed Hall of Science Room 330

The pneumatic conveying system that transports electric arc furnace dust from steel production at Nucor Steel Kankakee Inc. experiences blockages within the piping system which requires manual dislodging. The project's purpose is to prevent the regular formation of blockages and to automate the detection, location, and elimination of the blockages that do occur.

******

The current dust transport system Each baghouse house currently has its own dust transport system that transports dust to our central load out building. Nucor produces 28.1lbs of dust for every ton of steel made. Nucor Kankakee is permitted to produce 1.2 million tons of steel. The dust is collected in each baghouse by filter bags that collect and drop the dust in a hopper. The hopper drops dust into a screw conveyor that carries the dust to the transporter associated with the baghouse that generates the dust.

Each system consists of two tanks that are stacked on top of each other with a gate that separates the two tanks. The top tank receives the dust from the screw conveyor as the initial holding tank. Based on the fill level of the top tank the gate will open and allow dust to drop down into the bottom tank. Once the gate closes the bottom tank becomes pressurized and it blows the dust to the silo in the load out buildingagajanian (positive pressure).

Due to the system being positive pressure if we have a leak then dust is continuously blown outside the system. Once the dust is outside the system we cannot load the dust back into the system. A system needs to be designed to eliminate the potential for spill if containment in the piping is lost.
