Cracking - can occur at both front and rear ends at any position around the furnace tube plate but most common cracking is at the bottom of the tube plates. > Get A Quote >

Analysis on High Temperature Corrosion of a 600 M

2019-10-9 · Abstract: Aiming at the problem of corrosion occurred in the cold ash hopper area of a 600 MW coal-fired boiler after low NO x combustor retrofitting, the cause analysis is conducted in this paper by adopting testing and numerical simulation. The test results show that the volume fractions of H 2 S and CO have bigger promotion at the primary and reducing zones of the furnace after retrofitting. > Get A Quote >

Monitoring Dissolved Oxygen in High-Pressure Boile

2019-7-1 · Maintaining Water Quality in High-Pressure Boilers . Dissolved oxygen, or DO, is one of the most important water quality parameters to control in a boiler system. It is the primary corrosive agent of steam-generating systems. Even low concentrations of DO can be highly destructive, causing localized corrosion and pitting of metal system components. > Get A Quote >

Boiler Blowdown Analysis In An Industrial Boil

2015-8-5 · Boiler Blowdown Analysis In An Industrial Boiler International organization of Scientific Research 23 | P a g e There are two sources of blow down from a steam boiler; bottom blow down and surface blow down. Bottom blow down is the removal of the sludge which accumulates in the bottom of a fire tube boiler, or in the mud drum of a water tube > Get A Quote >

Tube Damage Mechanism and Analysis in Feed Wate

Boiler Tube Failure Analysis - Jonas I

2016-11-3 · Boiler Tube Failure Analysis. It is estimated that the cost of water/steam-side boiler tube corrosion is over $1.1 billion per year. cuts should be made with an electric or air powered reciprocating saw or grinder with a thin cut-off wheel to obtain high quality cuts. Tube ends should be sealed with tape to prevent contamination or loss > Get A Quote >

Characteristics of Water-Side Deposits in Boiler Tub

2018-2-2 · Another problem associated with water chemistry and water-side deposits is the corro- sion of the tube. A common corrosion problem is the pitting of tubes due to the ingress of oxygen into the boiler water. The oxygen tends to attack welds and backing rings preferen- > Get A Quote >
