Flue Gas - an overview | ScienceDirect Topics

The hot flue gas holds an appreciable amount of energy. Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam. In other units, the flue gas is exchanged with boiler feed water to produce steam via the

Why Is My Boiler Losing Pressure Q&A

Boiler losing pressure problem and cures. Before we explain about your boiler losing pressure, we will give you just a little history. The combination boiler was invented in the mid 1800s but not in the way we use it for central heating or hot water today, it was only in the early 1960s that there was some serious inventions leading to what we have today.

Boiler Efficiency and Combustion - beta.spiraxsarco.com

Flue gases on steam boiler plant are not condensed, therefore the actual amount of heat available to the boiler plant is reduced. the substantial pressure drop created over the orifice when the fuel is discharged into the furnace results in atomisation of the fuel. Putting a thumb over the end of a garden hosepipe creates the same effect
