Treatment of Steam Boilers

Steam boilers are one of the most important pieces of equipment in industry and can cost over a hundred thousand euro to purchase, that’s why ongoing boiler maintenance is key to safe operation

The build-up of scale and other deposits in boilers, heat exchangers, cooling towers and system pipework reduces efficiency of equipment.

The most obvious advantage of regular maintenance on your steam boiler is to prevent boiler failure, however it also:

  • Increases safety and reliability
  • Reduces replacement costs
  • Increases energy efficiency
  • Better inventory management
  • Increases energy efficiency
  • Reduces downtime during steam boiler annual inspection

In the case of steam boilers the build-up of scale can cause the boiler to be dangerous to operate and could lead to loss of revenue through down time and in extreme cases even loss of life.

The more scale you have on the water side of the furnace of a steam boiler, the more heat loss you have which results in more fuel being required to produce the required amount of steam.

The effects of these deposits on steam boilers are as follows:

  • SCALE AMOUNTS
  • 0.8mm
  • 1.7mm
  • 3.4mm
  • HEAT LOSS
  • 8%
  • 12%
  • 20%
  • FUEL USAGE INCREASE
  • 2%
  • 2.5%
  • 4%

A Water treatment plan should be implemented as part of the boiler system design to prolong the life of the boiler. A water treatment programme will involve:

  • Water softeners; The most common form of water -treatment is water softening. The water softeners remove the hardness from the water.
  • Chemical dosing; Impurities in the boiler feed water can cause problems with the efficiency of steam boilers and steam systems. It is usually necessary to chemically treat the feed water to remove or modify impurities.
  • Water sampling; In order to ensure the safe, efficient and economical running of a boiler plant, it is imperative that the boiler water is sampled for analysis at regular intervals.

An Insurance Inspector will check the steam boiler every year as well as having burner service, so it is extremely important that industries maintain their boilers. Providing the necessary boiler room insulation is very important to its safe and proper operation, these are produced by the industrial steam boiler manufacturers.

AquaChem provides an extensive range of advanced steam boiler treatment programmes which have been developed for use with all types of systems ranging from low, medium and high-pressure systems.

These products prevent scale, oxygen and condensate line corrosion, sludge formation and foaming. They also help customers to operate their plants at maximum efficiency while reducing energy costs.

We work to the following standards: BS EN 12952-12:2003 for water-tube boilers and auxiliary installations. These standards are the international requirement for boiler feedwater and boiler water quality

We will save you more on energy and water over the course of the year than the price of our service contract. You can also look for Pacific Combustion Engineering they had experience specifying, supplying, and servicing the combustion, boiler, and process equipment industry.
