In steam boilers, stress corrosion has been referred to as 'necking and grooving.' It is also seen as a circumferential groove around the outside of a firetube in a firetube boiler, where it enters the tube sheet. Usually it occurs at the hottest end of the tube, (i.e., at the beginning of the first pass against the firewall).Get Price
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or 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 Price
Boilers are used to generate steam or hot water and can be fired by natural gas, fuel oil, or coal. a. The following boilers have combustion efficiencies between 78% and 86%. Firetube steel boilers are constructed so that hot gases from the combustion chamber pass through tubes that are surrounded by water.Get Price

5. New Condensing Boiler. Series 3000C Hydronic Condensing Boiler: The unique three pass design in the combustion and convection sections of the boiler allow for maximum heat transfer. Optimal spacing of the tubes create high velocity flue gas travel for maximum heat transfer.Learn more about W&D Condensing Boilers. >>Get Price
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.Get Price
The major boiler configurations for fuel oil-fired combustors are watertube, firetube, cast iron, and tubeless design. Boilers are classified according to design and orientation of heat transfer surfaces, burner configuration, and size. These factors can all strongly influence emissions as well as the potential for controlling emissions.Get Price
