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; PottertonGet a Quote

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.Get a Quote

Feb 17, 2016· This may be caused by a combination of dirty heating surfaces, over firing, water-side scale buildup, excessive draft or excessive velocity of the water inside the boiler. If the stack temperature is too low, the flue gases will condense and damage the boiler, flue and chimney unless it is a boiler designed for condensing.Get a Quote
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 ...Get a Quote
