Understanding Coal Power Plant Heat Rate and Efficiency

Because approximately 3,412 Btu/hr equals 1 kW, we can easily determine the thermodynamic efficiency of a power plant by dividing 3,412 by the heat rate. For example, a coal power plant with a ...


SECTION 5 Methods of sampling and analysis

Finished feed can be sampled as it is transfer-red to the delivery vehicle if the feed is in the bulk form. In the case of cattle feed that is mixed during transport, collecting the sample from the feed bunk is an acceptable practice. Any sign of non uniform material, which includes differences in shape, size or color of

Speeds and Feeds 101 - In The Loupe

Feed rates assume a linear motion. However, there are cases in which the path takes an arc, such as in a pocket corner or a circular interpolation. Just as increasing the DOC increases the angle of engagement on a tool, so does taking a nonlinear path. For an internal corner, more of the tool is engaged and, for an external corner, less is engaged.


Air Cannon Solutions - Martin Eng

To preserve the life of the air cannon's piston and sealing o-rings, oil was added to the air supply. But as the air cannons would discharge the oil would collect on the filter, causing the filter to plug or bind. Filter efficiency would go down, which in turn reduced plant output and increased maintenance problems.
