Exploding the misconceptions and myths about arc flash issues

As a member of the NFPA 70E Committee and an instructor, I hear it all. There seems to be some common misconceptions among people that are like urban legends; they just don’t go away. One of my favorites is that “You don’t have to worry about arc flash below 240 volts.” While it may be true that an arc is more difficult to sustain at lower voltages, there have been some ...

Is Your Boiler the Best It Can Be?

Few energy devices are as universally used in industrial plants as are boilers. Because they are seen as a mature technology, boilers often don’t receive the regular attention given other industrial equipment. Yet because it is the largest single energy consuming device in the plant, the industrial boiler should be at the center of interest in most energy efficiency improvement plans.

Using technical assessment to identify root cause

A large pulp mill was shut down due to failure of the forced draft fan on its recovery boiler. Excessive vibration of the inboard bearing had broken the cooling water line inside the oil-filled bearing housing and flushed out the oil. The bearing journal had overheated, cracked and melted the Babbitt causing heavy scouring damage to the shaft surface.

Find, track the right metrics

Performance monitoring is not new. The concept of regular reporting has been around for as long as manufacturing operations have been in place. However, the pursuit of real-time performance management (RPM) requires managers to actively consider which metrics effectively track key processes and enable process improvements.
