Eight tips to keep steam dry and clean
Maintaining steam quality can reduce plant downtime, improve energy efficiency and minimize the use of chemicals and water.
1. Keep contaminants at bay by checking the total dissolved solids boiler blowdown rate.
2. Make sure the first stream trapping point after the boiler goes straight to waste in case any contaminants are carried over from the boiler.
3. Check to see if the chemical dosing is accurate. Too little, water quality will suffer, too much, and you are wasting costly chemicals.
4. Aim for maximum condensate return. In a well-maintained system, condensate will be more pure than any top-up water.
5. Check the feedtank to see if it is at the optimum temperature. A higher temperature is energy efficient and minimizes corrosion by driving off dissolved gases.
6. Use a sample cooler to improve the quality of samples and make your water-quality monitoring more reliable.
7. Avoid overloading the boiler, which may lead to water being carried over into the steam system.
8. Use a conductivity meter to quickly and accurately check the quality off feedwater, boiler water, and condensate.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
