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
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
