Boilers

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure

the issue of scaling. An open design eliminates tube plugging. Falling film liquor is evaporated on the outside surface of the tubes by the steam/vapor on the inside. If scaling occurs, the convex shape of the tube surface and the open design of the unit make on-line washing easy. Figure 2. The TUBEL concentrator addresses scaling.

Welded roll forming system versus tube mills: What's the ...

In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been fine-tuned to run a specific diameter range, typically at fast speeds (see Figure 1 ). Diameter range is mentioned because a tube mill welds a round product.

Introduction to Milling Tools and Their Application

Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.

Steam & Condensate System Improvements

in a Thunder Bay paper mill in 1967, which when combined with new open-mesh dryer fabrics in the 1970s, flooded the dryer pockets with low-pressure air, thereby lowering and leveling the humidity across the machine. These systems provided tremendous paybacks by increasing production rates and allowing higher sheet moisture levels.
