Anti-fouling and anti-corrosion of thermal systems

Boiler Anti-scale and Anti-corrosion Solution

A boiler is a device that transfers the heat released by fuel combustion to water and produces hot water, hot steam, dry steam or saturated steam. In general, devices that convert water into steam are called boilers. Boilers are divided into high-pressure, medium-pressure and low-pressure boilers based on their working pressure, which are used in steam turbines, steam turbine-driven pumps, reboilers and strippers, or to keep tanks and equipment warm. Hot water boilers and hot water are also fire-tube boilers that are capable of producing water at a temperature of 90˚C to 135˚C. The working pressure of these boilers is less than 8bar, which is used in central heating and air conditioning systems and heating absorption chillers, swimming pool and sauna facilities, industrial facilities, etc.

Boiler Optimization

There are two main flows in boilers, controlling these flows will optimize boilers. These two flows include fuel and water flow. Since the water entering the boiler has low hardness, the carbonate and sulfate compounds in the water precipitate due to the heat. Over time, these deposits increase and act as an insulator against heat transfer. As a result, energy consumption increases and if no action is taken to eliminate these deposits, it will increase boiler corrosion and wear. Therefore, it is necessary to use materials to prevent the formation of deposits and prevent corrosion, which will lead to increased efficiency, reduced energy consumption and reduced boiler wear.

Control of deposits and corrosion in boilers

To control the rate of deposits and corrosion in the liquid phase of the boiler, polyphosphate-based materials should be used. Anti-scaling and anti-corrosion solutions for boilers have buffering properties and minimize pH fluctuations, which is done without using alkaline compounds (sodium and potassium hydroxide) in the composition of the main material. Also, this solution, by forming a corrosion-resistant film and neutralizing carbonate and sulfate compounds, shows high performance in controlling sedimentation and preventing corrosion. It should be noted that great care must be taken in selecting anti-scaling and anti-corrosion solutions for boilers so as not to cause any foaming problems in the boiler.
