Boiler System Information
Boilers are used in buildings to produce hot water in a simple, economical, and effective way to meet domestic hot water needs, while also providing storage. One of the most commonly used plumbing equipment, boiler systems, answers to the most frequently asked questions are as follows.
Where are Boilers Used?
Boilers are usually used in centralized hot water preparation systems in places where people live in groups. They are used in places where there is a high demand for hot water, such as factories, barracks, hotels, dormitories, apartment buildings, hospitals, and construction sites, where the number of people opening the tap at the same time is high.
How to Use Boilers with Plumbing Equipment?
Boilers generally use hot water provided from boiler or cascade systems as the heating fluid. A closed circuit is created through a pump and circulation is provided. There are thermostat inputs on the boiler for temperature control. Based on the measured values from these inputs, flow is cut off with pump control. Heating is provided at maximum efficiency by adjusting the input temperature and pump speed according to the desired heating time.
Why is Enamel Important in Boilers?
To ensure hygiene, boilers are coated with titanium enamel. The enamel used in boilers should not contain heavy metals in the main structure made of boron and silicon. It should be produced in accordance with RoHS values and European Standards.
Why Should Magnesium Anode Rods be Used?
Enamel and galvanized coated boilers should be protected against corrosion with magnesium anode rods. The magnesium anode dissolves in the tank through electrolysis, sticks to the points where enamel needs and extends the life of the tank. It is important that the magnesium anode rods used in boilers comply with European Standards components. How Should Resistance Tests be Performed in Boilers? It is very important to test the corrosion processes of surfaces in contact with water in boilers. In the boiler tests applied according to European Standards, a 10% citric acid solution is used. The citric acid solution is applied to the enamel surface for 15 minutes, and the acid resistance is determined according to the deformation it causes on the enamel in the end.
What is the Citric Acid Resistance Test in Boilers?
The citric acid test is conducted according to ISO 2722 standards. In boiler enamel tests, the citric acid solution is applied for 20 minutes. MIT Boilers are in the highest class, AA, according to this test result.
What Should be the Sheet Quality in Boilers?
MIT Boilers use low carbon hot-rolled sheets suitable for cold forming according to Ereğli TRKK 6222 standards. This sheet is resistant to aging, suitable for welding, has deep drawability properties, and is suitable for enamel coating used in single/double-layer or single/double firing. In addition, S355J2 (ST 52-3) sheet is used in galvanized immersion accumulation tanks.
How is the Hot Water and Steam Resistance Test Performed with Boilers?
The test piece is subjected to a 48-hour hot water and steam test. At the end of this process, the enamel on the test piece decreases slightly. According to European standards, the highest acceptable amount is 3.5gr/m². This amount is only 2gr/m² for MIT Boilers.
How is Boiler Selection Made?
The most important criterion in boiler selection is the usage area. Boiler selection should be made by mechanical engineers based on specific criteria. Boiler selection is made based on the conditions of the Chamber of Mechanical Engineers according to the hot water needs of collective settlements. Calculated data is based on the hourly water requirement and all water usage sources (faucets) are calculated by counting them open for 1 hour. In short, boiler selection should be made based on the hourly production value and the simultaneous use factor.
What are the Advantages of Boilers?
Boilers can preserve hot water inside for a very long time when not in use. While providing high efficiency with advanced insulation materials used, they also protect boilers from external factors. Coils in boilers should be designed to prevent the formation of cold spots. Fast Boilers prevent the formation of cold spots due to their special coil designs and do not allow bacteria that cause Legionnaire's disease to survive. Thanks to the titanium enamel coating, it prevents bacteria growth and corrosion.
