The feedwater must be specially treated to avoid problems in the boiler and downstream systems. Untreated boiler feed water can cause corrosion and fouling. Boiler corrosion. Corrosive compounds, especially O 2 and CO 2 must be removed, usually by use of a deaerator. Residual amounts can be removed chemically, by use of oxygen scavengers.Get Price
The treatment and conditioning of boiler feed water must satisfy three main objectives:. Continuous heat exchange; Corrosion protection; Production of high quality steam; External treatment is the reduction or removal of impurities from water outside the boiler. In general, external treatment is used when the amount of one or more of the feed water impurities is too …Get Price

Off-line boiler corrosion is usually caused by oxygen in-leakage. Low pH causes further corrosion. Low pH can result when oxygen reacts with iron to form hydroferric acid. This corrosion product, an acidic form of iron, forms at water-air interfaces. Corrosion also occurs in boiler feedwater and condensate systems.Get Price
Jul 09, 2019 · (In some ways, the word "boiler" is a bit of a misnomer, as the boiler doesn't actually boil the water.) Blocked/frozen condensate pipes can cause this sound due to the water gathering in the condensate sump. Another common reason is the buildup of limescale and corrosion inside the heat exchanger.Get Price
Stress corrosion is frequently seen on condenser tubes and boiler tubes in the area where the tubes are rolled into the tube sheets. 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.Get Price
Corrosion weakens boiler metal by the thinning (removal) of the metal. Corrosion causes pitting and channeling of the metal, which results in the thinning of tubes, piping, and other boiler components. Corrosion is primarily caused by oxygen in the boiler water. Feedwater is treated to remove oxygen by heating and/or chemical treatment.Get Price
Oct 04, 2020 · Boiler Leaking Water from Bottom: The Fix. A leaky boiler is often the result of a small hole or a worn-out seal. This sort of problem does not affect the functions of the boiler but it can still make a mess and make you worry about how safe it is.Get Price

High boiler solids will lead to foaming, priming, surging and carry over. These problems can be overcome by proper, daily blowdown of the boiler. Alkalinity. The alkalinity of boiler water should be sufficiently high enough to protect shell and plates against acidic corrosion, but not high enough to produce carryover.Get Price

Sep 26, 2016 · Aluminum: deposits as scale on the boiler interior and can react with silica to increase the likelihood of scaling; Hardness: also causes deposits and scale on boiler parts and piping; Dissolved gasses: chemical reactions due to the presence of dissolved gases such as oxygen and carbon dioxide can cause severe corrosion on boiler pipes and partsGet Price
A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler …Get Price

Corroded pipes, high pressure and loose joints are all common causes of a boiler leaking water. If your boiler was only installed recently, the leak could be down to poor installation. Should you spot even the slightest leak, contact a heating engineer right away. The water could lead to corrosion, rust or cause electrical parts to malfunction.Get Price
Dec 22, 2016 · There are a few possible causes for your combination boiler to trip the electric, however it mainly comes down to a potential leak or moisture build-up. Leaking boilers can occur due to corrosion, faulty pump seals or high pressures and should be assessed by a professional heating engineer.Get Price

In the case that the boiler is leaking around the pipes or tank then that's a strong indication of corrosion. Otherwise, it could be the result of a poor installation. Either way, we recommend calling out an engineer who will be able to diagnose and fix the leak.Get Price
