The Benefits of Floating HRSG Duct Liners

The heat recovery steam generators (HRSGs) of combined cycle power units utilize the exhaust gas from the combustion turbine(s) to generate steam for additional power production. The harsh environment that exists in HRSG inlet ducts requires careful design/installation of insulation and liner plates.  Expansion and contraction issues play a great role in proper design.

Is Your Wet Scrubbing Tower Working?

Is your scrubbing tower working? A wet scrubbing tower is used to clean odors, particles, mists, and vapors from a gas stream. The gas is forced through the tower. As it moves from inlet to outlet it is washed and cleaned. The washing is done with suitable chemicals that remove the active components in the gas flow. The gas is cleaned to environmentally acceptable levels and discharged to atmosphere.

Diagnosing a Bent Shaft

Diagnosing a bent shaft with vibration analysis is easy to do, especially when you can visualize its movement using 3D animations. Vibration patterns for different faults can look similar to each other. This is why it is always best to start with the machine, consider what faults are most likely and then take data in the proper test points and axes to find the most likely faults. It can get complicated, but 3D animations make it easier to visualize what is going on.

Experiences with Magnetic Drive Pumps

Magnetic drive pumps (also called magdrive pumps) come in three varieties – canned motor pumps, all metal pumps, and plastic lined metal pumps. They are sealless and cannot leak into the environment. Long, repair-free service life depends on recognizing the limitations of these pumps. This article covers issues with using direct mounted, lined magdrive pumps experienced ‘in the field’.

Motor Brush Facts and Maintenance

A motor brush is not a brush at all in the traditional sense. It is actually a carbon or graphite cube, commonly held in place by a spring, that acts as a conductor between the electrified stationary and rotating parts of a motor. The whole brush assembly is made up of a carbon block, one or more shunts, a spring and a holder. The carbon blocks are easily replaceable and are therefore intended as a wear part to prevent damage to more costly motor components.

The Pump Impeller: Pump Life Extension

A standard centrifugal pump impeller is constructed of a group of elongated, solid-walled chambers attached together in the shape of a circular ring. The ring is spun quickly and the liquid that enters the inside end of the chambers is flung out at high speed from the other end. Figure No. 1 shows a section through centrifugal pump wet-end showing regions of low and high pressures.
