Boiler Water
Can you identify some of these challenges with boiler water?
Already from the beginning wrong water treatment in a steam boiler, steam generator or high pressure hot water boiler will lead to a negative shift in “total cost of ownership” (TCO). This will cause increased costs and major problems for you and your business. Some of these problems are:
- Lack of capacity which leads to investing in an “over-sized” plant.
- Interruptions of operating time.
- Increasing operational and maintenance costs.
- Increased fuel consumption.
- Increased water consumption.
- Increased electricity consumption.
- Loss of productivity.
- Unnecessary environmental impacts and Co2-emission.
- Hazardous work environment.
- Replacement of expensive equipment etc.
- Expensive cleaning/descalings.
Common Problems
When oxygen is present in the boiler the following process will happen: (2Fe3O4 + ½ O2 -> 3Fe2O3), which means that the protective magnetite film is corroded and a pitting-type corrosion in the boiler will take place. This type of corrosion can easily penetrate thick steel. The speed of corrosion will increase if the pressure and temperature are increased.
If you absorb the oxygen by using an oxygen absorbing chemical, such as sulphite, DEHA, ascorbic acid or tannins, the chemical reaction is blocked (as an example using sulphite the chemical reaction will be SO32- +1/2O2 -> SO42-). This way you avoid oxygen corrosion. (pitting)
Furthermore the formation of magnetite is stimulated (Fe + 2H2O -> Fe(OH)2+H2 and the temperature > 120 oC 3Fe(OH)2 -> Fe3O4 + 2H2O + H2)
Carbon dioxide leads to the formation of carbonic acid in the condensate system, which results in corrosion of the system´s parts (CO2(g) + H2O -> HCO3- + H+) = a pH value of 5-6 in the condensate.
Carbon dioxide can easily be neutralised by using volatile amines, as well as amines that are approved of according to the national or international standard
If the sludge is not properly spread, it will result in an accumulation of sludge, which reduces the circulation and affect the thermal efficiency.
Aqua-x only offers environmentally friendly boiler protection programs. These programs include the use of high-tech polymers, efficient oxygen scavengers, and sludge dispersing agents. Using these will make the sludge discharge from the boiler when performing the regular blow down intervals.
The products also have a foam-suppressing effect, so the highest possible concentrations are possible without the risk of priming. (carry-over)
