HIGH MILEAGE STEAM

摘要

Energy, or more specifically wasted energy, is sometimes visible and you can notice immediately if an improvement in energy efficiency is made. Ask the operators of Ponderay Newsprint's (Usk, WA) PM 1 about wet end steam spillage and they will tell you the air is much clearer around the press section since the installation of a new Metso IQSteamPro steam profiler, replacing an older unit installed about 12 years ago. If the steam is not spilling out of the machine, as it was before, the energy it contains is going into the paper sheet where it helps to drain water in the presses and improve the sheet moisture profile. And that is definitely more energy efficient, as proven by mill steam consumption statistics. Just like a modern car that gets better gas mileage, the Ponderay machine is getting better steam mileage.
