Johnston Boiler Technical Paper in support of 4:1 over 10:1 This paper presents a case where it is more efficient to run a 4:1 in an on-off mode rather than run a 10:1 boiler at 10% fire. The paper assumes that the 4:1 boiler can be shut off for long periods of time, and the 10:1 boiler uses large amounts of excess air at low fire.

How Do Steam Boilers Work - What Do Steam Boilers Do?

What Does A Boiler Do? A steam boiler is a type of heat exchange system where water is heated to its' boiling point via combustion of a fuel blown through a tube submerged in water. The heat produced in this system is then rejected into the system as steam. This steam flows through pipe systems to the equipment that is being heated, whether it be hot water coils in air handling units, or

Boiler Safety and Role of Low Water Levels

Controlling the boiler drum level is complicated as the "water level" in a steam drum is actually a fairly unstable mixture of water and steam bubbles that shrinks and swells as the pressure changes. This is because of the fact that as the steam demand increases, the pressure in the boiler drops causing the water level to rise.
