Boiler Questions and Answers regarding Your Boiler

Our 1,200,000 lb/hr steam boiler normally operates at around 3% excess O2 or 15% excess Air. If it operated at 3% excess O2 what would be the approximate % boiler efficiency loss? Answer. The term Boiler efficiency is a generic term that could mean many things. The best definition of your boiler's efficiency is the fuel-to-steam efficiency.

The Temperature in Your Boiler and the Dangers of

Mar 12, 2014 · The energy applied to the water in the tank raises it to high levels, but not to the point that it converts the water into steam. Boilers originally did use steam heat to provide warmth—it was how they earned their name—and people still expect to see boilers in movies explode with geysers of steam when bullets puncture them.

What Should The Boiler Pressure Be When The Heating Is On?

To increase the boiler pressure you will need to add mains cold water to the system using the external filling loop. Make sure that the boiler is turned off and completely cooled down before you start. You should only have to increase the boiler pressure once or twice a year.

Reasons why the water is bouncing in the - Heating Help

Jun 25, 2014 · The boiler is priming or foaming. Priming is the violent bouncing of the water. Foaming happens when bubbles form on the surface of the water. Foaming follows priming, and while priming is bad, foaming is worse. Foaming throws water up into the system and creates water hammer, uneven heating and water level problems within the boiler.

How can I increase PSI in my boiler? (pics attached) | DIY

Dec 18, 2007 · Where the cold water comes into the boiler unit, I noticed a "backflow preventer" unit which has a small lever on the top of the unit which, when flipped, sounded as though it began allowing *more* water to flow into the unit. Almost immediately (within 10 mins, I noticed the PSI levels begin to increase). As you can see by the gauge picture

Steam and Condensate - A basic overview of a steam system

Steam passes from the boiler into the steam mains. Initially the pipework is cold and heat is transferred to it from the steam. The air surrounding the pipes is also cooler than the steam, so the pipework will begin to lose heat to the air. Insulation fitted around the pipe will reduce this heat loss considerably.
