Boilers & Steam Generating Systems

Boilers and steam generating systems are an essential component in many commercial, industrial and process applications where their primary purpose is to transfer energy from one part of the system to another. Such systems use water (steam) at elevated temperatures which is a highly efficient means of energy transfer.

Problems Affecting Boiler Water Systems

If a boiler system is poorly maintained or the water used within it is left untreated it can lead to a number of serious issues that will affect the integrity and performance of the boiler and steam-raising system. The problems associated with poor boiler water treatment and system maintenance can include scaling, corrosion and deposition.

  • Scaling

  • Corrosion

  • Deposition

Such problems can affect steam quality, reduce heat transfer efficiencies, increase energy costs, and reduce asset reliability and life-expectancy. In the worst cases poor boiler maintenance can also result in catastrophic system failure which can be very hazardous.

To combat these problems the water used in both the boiler and the wider steam-raising system will require suitable treatment which would typically include the boiler together with the feed-tank, feed-lines, and steam and condensate return systems.

Successful Boiler Water Treatment

Successful boiler operation requires a holistic approach to the maintenance and protection of both the boiler and wider steam system against the detrimental effects of scale formation, corrosion and deposition.

A well-managed boiler system will help to optimise costs and operational efficiencies, reduce downtime, achieve water and energy savings, maintain steam quality, and increase plant reliability and safety.

Water Treatment Services holistic approach to the successful management of boilers and steam generating systems typically involves the following stages:

  • Pre-Treatment

    Suitable pre-treatment of the boiler feed water, this may include commercial water softeners and industrial reverse osmosis units.

  • Protection

    Protection of the boiler and steam system.

  • Deposit Free

    Maintaining clean internal surfaces free from scale and deposition using a range of techniques for the treatment of industrial boilers and steam generators, heritage steam and marine boilers.

  • Condensate Return

    Maximise levels of condensate return.

Controlling Scale Formation in Boilers

Scale formation on the internal surfaces of boilers and steam systems is a significant issue. If left untreated scale can build-up on the internal surfaces of pipework, boiler tubes and other heat transfer surfaces to act as an insulator and reduce boiler efficiencies significantly. It can also cause the boiler and pipework to overheat, and in extreme circumstances catastrophic failure can result.

Boiler scaling occurs when high temperatures reduce the solubility of calcium and magnesium salts commonly found in the feed water allowing them to precipitate out and on to internal surfaces.

To control boiler scale formation it is therefore important to pre-treat the feed water, removing as effectively as possible any hardness salts before they enter the boiler system. This can be achieved using a commercial boiler water softener and specialist scale inhibitors. Reverse osmosis (RO) equipment can also be considered for the pre-treatment of the boiler feed water.

To ensure the steam system is kept under full control at all times the quality of the boiler water should also be tested regularly to ensure the boiler treatment programme is operating effectively and the correct water conditions are being maintained.

Corrosion Control for Steam Boilers

The internal environments found within boilers and steam systems be extremely aggressive to the materials of construction and can cause a number of serious problems. Corrosion is one such problem and if left untreated it can increase costs, reduce asset reliability and life-expectancy, and in the worst cases it can cause catastrophic failure. The primary causes of corrosion in boiler systems are dissolved oxygen, acidity and excess alkalinity. The most common of these being oxygen associated corrosion which is caused by oxygen dissolved in the feed water entering the boiler system.

The oxygen contained in the water acts aggressively to create localised corrosion of the internal surfaces in the form of oxygen pitting. These corrosion pits are generally small but can sometimes grow, resulting in deep pinholes which if left to penetrate boiler tubes and other internal surfaces can affect their integrity and result in failure.

Effective boiler water treatment should be holistic in its approach and focus on the removal of dissolved oxygen from the feed water, whilst controlling both pH and alkalinity levels. This can be achieved through good system design, particularly feed-tank and condensate return arrangements) and the use of high performance boiler treatment technologies.

Steam Condensate Corrosion

Managing condensate water quality in your steam generating system is important as if left untreated it can cause a number of serious issues including acid and oxygen corrosion. This can lead to the failure of the condensate return lines and other system components.

Problems arise in the condensate system when steam condenses. As it does so it absorbs carbon dioxide and oxygen from the atmosphere to create corrosive water conditions which can be detrimental to the boiler system, but particularly the condensate return lines, threaded joints and elbow components. Oxygen corrosion acts aggressively on the internal condensate line surfaces to create localised pitting and potentially deeper pinholes. Pitting and pinholing can be controlled using boiler oxygen scavengers including tannin, sulphite or DEHA.

The formation of carbonic acid in the system will lead to general corrosion throughout the boiler system and can be controlled using specialist steam volatile boiler treatment chemicals including film forming and neutralising amines, or by pre-treatment of the boiler water using reverse osmosis or de-alkalisation techniques.

Boiler Blowdown

Boiler blowdown is an important component in the successful management of any steam generating system as it helps to remove accumulated sludge from the boiler, control levels of both suspended and total dissolved solids (TDS) and so maintain boiler efficiencies and overall steam purity.

It is also important to remember that blowdown, while important should only be performed when required as it can be very energy inefficient.

Sludge Deposition

The formation of boiler sludge occurs as the concentration of suspended solids, primarily from corrosion by-products and the deposition of solid hardness salts, increases in the system. If left unchecked the build-up of sludge can reduce heat transfer efficiencies and overall boiler performance.

Total Dissolved Solids (TDS)

As steam is generated in a boiler system water naturally evaporates and is lost to the atmosphere. As this occurs the concentration of TDS in the remaining boiler water increases and can cause a number of problems including carryover and foaming.

Carryover (see below) can cause steam contamination issues whilst foaming can reduce the heat transfer efficiency of boiler tubes and lead to overheating and premature failure. To prevent carryover and unwanted foaming it is therefore important to control TDS levels in the boiler water. This can be achieved by blowdown and the introduction of fresh, suitably pre-treated feed water.

Boiler Water Carryover

Carryover occurs when boiler water in its liquid form is “carried over” in to the gaseous steam. This can cause solids contamination of the steam and any process products it comes in to contact with. It can also result in damage to the boiler, steam system and other process equipment.

To prevent carryover and unwanted foaming it is therefore important to control the levels of contaminants in the boiler water (total dissolved solids). This can be achieved by blowdown and the introduction of pre-treated feed water.
