Gas Boiler Flue Regulations: Things to Know before .

Structure of the Flue. Usually a typical gas boiler flue looks like a 4-inch metal pipe that goes from the boiler’s top. Today there are two concentric pipes: for fumes out; for air in; Sometimes it is a 5-inch pipe. The size normally depends on a manufacturer. A 5-inch type is common to the boilers from such manufacturers as: Vaillant; Worcester; Potterton

This will ensure that all of the fuel is burned. The extra oxygen that is added to the combustion zone, however, enters at ambient temperature and it exits the boiler at flue-gas temperature. The flue-gas temperature of a typical boiler could be anywhere in the range of 300 to 500 degrees Fahrenheit range.

The cooled water or the condensed steam returns to the boiler where it can be heated again. Loss of water must be compensated by treated fresh water to avoid corrosion. Flue gases created by combustion are discharged into the atmosphere through a chimney. Particularly efficient systems additionally use the residual heat in the flue gases.

Fire-tube boiler - Wikiped

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low ...
