The bottom drain line on your boiler usually has two valves: a gate valve and a knife valve. The proper way to bottom blowdown a boiler is to start with both valves fully closed. Start by opening the knife valve, then completely open and then close the gate valve. Do this to both front and back drain valves if your boiler is so equipped.
2014-10-17 · operating a once-through supercritical boiler on OT include: • Lowering overall corrosion rates by forming a protective, double-oxide layer with a controlled amount of oxygen present in the condensate (This protective layer is considered to be more stable than the oxide layer formed using AVT.) • Decreasing boiler chemical cleaning frequency
