One of the most important aspects of a steam system’s efficiency is the quality of its steam. By quality, we mean moisture content. Wet steam is very inefficient. The process of ringing that moisture out of the steam takes place with modern boilers in the near-boiler header piping. Four aspects are critical: First, we must have sufficient height in the risers to allow some of the moisture to drop out. We strive for 30″ on every install. Second, dual risers out of the boiler are always used. This slows the velocity of the exiting steam, making it less likely that it will pull moisture along with it. Thirdly, we install oversized header piping which additionally slows down the velocity of the steam. Standard threading equipment at most companies stops at 2″ diameter pipe. This is inadequate for all but the smallest boilers, -but is the reason why it is so often utilized. At NES, we have the proper equipment to make the header whatever size your system requires. Lastly, we always utilize dropped headers, which serve to wring the last of the moisture out of the steam before it travels into the system. NES = Highest Quality Steam
