Finding the Root Cause of Boiler Tube Failures - babcock.com

Symptoms: Aggressive localized corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water treatment equipment.

FIRESIDE TUBE CORROSION IN AN INDUSTRIAL RDF-FIRED

Various means of protecting fireside tube surfaces from deterioration have been attempted since 1975. These are: (a) Carbon steel and alloy weld overlay of wa­ terwall tubes. (b) Carbon and alloy shields on superheater plat­ ens and boiler convection and waterwall (burner area) tubes.

Boiler Fireside. The fireside of your boiler will include all refractories, furnace, tubes, and tube sheets. 1) Use a bright light to visually inspect the Boiler Fireside surface condition. Check for blistering and pock marks. Blistering and pock marks are an indication of corrosion from flue gas condensation.

A Checklist of Boiler Maintenance Tasks

• Check the pump alignment on all the base-mounted pumps in the boiler room, and reset combustion using a combustion analyzer for reading O 2, CO and NOx emissions. Annual Maintenance • Properly shut down the boiler and open the access doors to expose the fireside of the boiler. • Thoroughly clean the tubes and tube sheets.

Clean ash, soot and other products of combustion from fireside tube and tube sheet surfaces immediately after shutdown. Flush these surfaces completely with water to dissolve, dilute and remove any remaining sulfur compounds. Dry by blowing air through the boiler. All cleaned surfaces should be coated with a good grade of light oil to prevent rust.

Fireside corrosion in the superheaters and reheaters of coal-fired units is known as coal ash corrosion, in oil-fired units as oil ash corrosion, and in refuse-fired boilers as ash corrosion. Sometimes, fireside corrosion is also referred to as hot corrosion. The mechanism in each case is similar,

Soot & Scale Affects Boiler Performance | Goodway

Oct 11, 2016· Soot and scale are removed by vacuuming, or by water flow, with watertube boilers. For severely scaled tubes, equipment is available that rotates a flexible shaft with a cleaning tool and vacuum (or water flow) attachment through the tubes. Every boiler cleaning program should include regular efficiency testing.

Cracks near a weld or attachment are a separate category from those away from these stress concentrators. Holes, pits and gouges are three examples of corrosion and may occur on the fire/gas side or on the water/steam side of the tube. Deformation includes thinning from the water or fireside and bulging or blistering.

Difference between Fire Tube Boiler and Water Tube Boiler

Mar 19, 2016· The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is the key difference between these boilers.

Characteristics of Water-Side Deposits in Boiler Tubes

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- tially and can lead to eventual failure. In addition there are two major types of water-side attack of furnace tubes which can result in catastrophic failure of tubes and cause forced outages.
