PEH:Drilling Problems and Solutions - PetroWiki

For example, during angle building with a downhole motor (sliding mode), rotation cannot be induced. With the new steering rotary systems, this is no longer a problem. However, pipe rotation can cause cyclic stresses that can accelerate pipe failures due to fatigue, casing wear, and, in some cases, mechanical destruction to openhole sections.

Fire and Explosion Hazards in Cement Manufacturing ...

Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk.

Environmental Assessment of Coal Transportation

At present only one proposal for a coal slurry pipeline would entail water withdrawal from the Missouri River Basin. This is the pipeline proposal initiated in late 1973 by Energy Transportation Systems, Inc. The coal slurry pipe- line would pump coal from Gillette, Wyoming, to White Bluff, Arkansas (Ref. A-3).

Blaster's Training Modules - Module 4 - Blasthole Drilling

Rotary Drill Rigs Many rotary rig masts have pinning capabilities that permit drilling at angles as much as 30 degrees out of the vertical. Drilling in this manner is necessary at large surface coal mines where overburden will be cast. Typically, angles range from 10 to 15 degrees on the back row and 20 to 23 degrees along the front row.

Ball joint connections can be used to help hold two tubes together in a way that allows some movement at the joint. One of the keys to forming in the swage box is holding the tube firmly with the collets and collet holder. The forces required to form the new metal shapes are great… 25,000 lbs of force exerted across just a few inches of diameter.

Cement Kilns: Firing systems

The use of pulverised coal for firing industrial furnaces was pioneered in the cement industry, and the perfection of the technique was a critical factor in the development of the rotary kiln in the 1890s. The desired requirement was for a system that could make cheap coal into a direct replacement for the more expensive fuel oil previously used.

Introduction to Pneumatic Conveying of Solids - AIChE

Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.
