Sep 03, 2020 · Copper in the boiler displaces metal from the tube surfaces and plates out on the tubes. This condition often occurs under existing scale and sludge deposits, which is known as under deposit Copper corrosion. Copper deposits are a serious problem in high pressure boilers.

Old "fire-tube" boilers often failed due to poor build quality or lack of maintenance (such as corrosion of the fire tubes, or fatigue of the boiler shell due to constant expansion and contraction). A failure of fire tubes forces large volumes of high pressure, high temperature steam back down the fire tubes in a fraction of a second and often

Aug 19, 2019 · Once it is heated, the steam generated is moved along downstream. Fire-tube boilers tend to be the cheapest type of boiler to produce, as they have a fairly simple construction but are typically limited for low to medium pressure applications due to the thickness of the outer shell containing the water.

Rupture disks are replaced after actuation or periodically as part of preventative maintenance or inspection. These devices are manufactured in accordance with provisions of the ASME Boiler and Pressure Vessel Code (ASME B&PV Code), Section VIII.They are certified by the National Board through a program that tests samples for correct burst pressure and flow resistance.

Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.
