Oct 10, 2020 · At the heart of a steam boiler is a cast-iron tank filled about halfway with water. A burner below the tank heats the water until it turns to steam. The steam rises up through a system of supply pipes to each radiator in the home. The steam heat is transferred to the radiator (and into the room via air convection), causing the steam ?/p>

Jan 13, 2015 · The starting point in any combustion system is the supply of fresh air. To avoid serious problems, the boiler must have an adequate supply of fresh air and a supply system that does not affect the boiler operation. An adequate, proper and consistent supply of fresh air must be supplied into the boiler room for burner combustion air. A rule of thumb is to provide four to six square inches of

Boiler/Burner Combustion Air Supply Requirements and

Air is present within steam pipes and steam equipment at start-up. Even if the system were filled with pure steam when used, the condensing steam would cause a vacuum and draw air into the pipes at shutdown. Air can also enter the system in solution in the feedwater. At 80°C, water can dissolve about 0.6% of its volume, of air.
