Basics of hot water heating boilers - Specifying Engineer

Sep 18, 2020 · The heat exchange surfaces for hot water boilers must be in contact with water to prevent the heat exchange surface from overheating. Low level water sensors are required to ensure this. Fuel and air are controlled in concert, but the quantity of fuel delivered is a function of thermal input required to control the boiler temperature.

What Pressure Should My Boiler Be? | Vaillant

A boiler's pressure gauge will usually sit between 1 and 2 bars when it is turned on. The exact recommended pressure level will vary depending on the boiler manufacturer, but generally, anywhere between 1.0 and 2.0 bar is ideal. The boiler pressure level will rise when heating a home or providing hot water. However, it should still stay below

Water Levels in Steam Boilers | Spirax Sarco

Water Levels in Steam Boilers. The task of any steam boiler is to provide the correct amount of high quality steam: safely, efficiently, and at the correct pressure. Steam is generated by heat from the combustion of fuel in a furnace, or by waste heat from a process. The heat is transferred to water in the boiler shell, which then evaporates to

Boiler Combustion | CleanBoiler.org

A boiler's excess air supply provides for safe operation above stoichiometric conditions. A typical burner is usually set up with 10-20% excess air (2-4% O2). NOx controls that require higher excess air levels can result in fuel being used to heat the air rather than transferring it to usable energy.
