Hospitals and care homes have traditionally been using steam in various ways. As goes for any system, continuity is an important factor.
The following problems may arise during the normal operation of steam boilers if no measures are taken:
- calcium deposits
- deposits of other salts on the boiler wall
- corrosion (rust formation)
- discharge of residual water
What can Kalsbeek do for you?
Paying attention to the above-mentioned four problems is important for the proper operation of the steam boiler. Kalsbeek can take these tasks off your hands. They provide the best possible composition of the water and make regular checks.
Kalsbeek can offer solutions for calcium, salts and corrosion, and makes sure you waste as little as possible water, energy and agents when discharging water. Every year, Kalsbeek checks the feed and boiler water several times for overall quality. Points of particular interest include the calcium, iron and salt contents. Product measurements and, if necessary, dosages are also adjusted.
This will eliminate any harmful process, so you can be assured of a properly operating steam boiler. At minimum costs for energy and water, of course.
Solutions for:
- Calcium deposits
- Corrosion
- Discharging water
The calcification level depends on the degree of hardness of the feed water. Calcium conducts heat approximately 300 times poorer than copper. Calcification has therefore a detrimental effect on the operation of the boiler. The results: higher power consumption and the risk of cracks in the boiler wall as a result of shrinkage stress below the layer of calcium deposits. For that reason the use of the right quality of feed water is recommended for the boilers. To prevent calcium deposits, it would be recommended to pre-treat the make-up water using a softener. Kalsbeek will be able to supply this equipment and regularly check the equipment as well as the quality of the boiler water.
Oxygen corrosion
As well as the risk of calcium deposits, the presence of oxygen in the feed water may also cause corrosion. Oxygen-binding substances must be added to the boiler water to prevent corrosion. Kalsbeek is a supplier of such products and also gives advice on the amount that should be added.
Discharging water
By reducing the amount of water through evaporation (in fact, that is what happens in the steam boiler) the content of minerals and added substances is rising. That is because these substances do not evaporate but remain in the boiler instead. One could say, the fluid becomes more concentrated by evaporation.
From time to time, some of the water must be drained from the boiler in order to retain the optimum quality of the boiler water; that is the so-called discharge of boiler water. This will cause the water level to drop; for the proper operation of the steam boiler you will have to raise the level by filling up with fresh water.
Discharging is always expensive. You purchased (costly) water, which you subsequently heated and treated. You would rather not discharge it into the sewer. With smart applications and additions, Kalsbeek reduces the frequency of discharge. For instance, we desalinate the water using a reverse osmosis device to further thicken the water without a problem. The advantages include: less discharge, lower purchase costs and lower environmental impact.
