  • APTI Course SI:428A Introduction to Boiler Operation: Self

    Thus, if a boiler produces two times the amount of its rated capacity, it operates at 200% of rating. Boilers are also classified by the pressure at which they operate. The five common groupings are: below 900 psi, 900 to 1000 psi, 1200 to 1500 psi, 1800 to 2500 psi, and 3500 to 5000 psi. Fire-tube boilers usually operate between 50 and 250 psi.Learn More

    the boiler. At the temperatures of boiler tubes in units with operating pressures below about 900 psi, carbon steel tubes corrode slowly enough to have an acceptably long life. In higher pressure boilers the corrosion rates are significantly higher. Until the early 1970s, all recovery boilers operated at relatively low pressures and used carbon Learn More

  • Black Liquor Recovery Boilers - An Introduction

    Above 900 psi, special corrosion protection (such as composite tubes, chromizing, metal spray coating and stainless weld overlay) is provided for furnace tubes. The furnace of a BLRB is generally taller than a utility or industrial watertube boiler of similar steam generating capacity, due to the sticky nature of the combustion gases.Learn More

  • Why Is My Boiler Pressure Too High or Too Low? - 7 Reasons

    Nov 02, 2019 · The green 1 – 1.5 bar is the safe spot where you want to be. If you are hitting over 2.5, then you have too much pressure in your boiler. If you are below 1 you have low boiler pressure. While gauges will go higher in most cases, a boiler will shut off or …Learn More

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

    When the heating is turned on your boiler pressure should be between 1.5 and 2 bar. Most boilers will highlight this area on the pressure gauge in green to help you see if the needle is pointing to the correct amount of pressure. Some boilers will also have the critical zones below 1 and above 2 marked in red to help you identify any issues.Learn More

  • Is My Boiler Pressure Too High? | Hometree

    Boiler pressure refers to the pressure of hot water running in your sealed central heating system, while water pressure is the pressure of the water coming through your taps. Boiler pressure is important for several reasons. Primarily, if you have low boiler pressure your system could cut out, preventing your central heating from working. Learn More


    If your pressure gauge is marked with a green zone and the needle has fallen below it, this is a sign that the gas boiler pressure is too low and action should be taken. If you have radiators that fail to heat up as they should, this may also be a sign that there is an issue with your boiler pressure and can be confirmed by checking the gauge.Learn More
