Boiler System Information
Boilers are used in buildings to provide hot water production in a simple, economical, and effective way to meet the needs of domestic water usage, while also enabling storage. One of the most commonly used plumbing equipment, boiler systems, the answers to the most frequently asked questions are as follows.
Where are Boiler Usage Areas?
Boilers are generally used in centralized hot water preparation systems in areas where people live in groups. Boilers are used in places where there is a high demand for hot water, such as factories, barracks, hotels, dormitories, apartment buildings, hospitals, construction sites, where the number of people opening taps simultaneously is high.
How are Boilers Used with Plumbing Equipment?
Boilers generally use hot water provided from boilers or cascade systems as the heating fluid. A closed circuit is created and circulation is provided through a pump. Thermostat inputs are available 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 entry temperature and pump speed according to the target 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 and should be produced in compliance with European Standards, keeping the RoHS values in mind.
Why Should Magnesium Anode Rod be Used?
Enamel and galvanized coated boilers should be protected from corrosion with a magnesium anode rod. The magnesium anode dissolves in the tank through electrolysis and adheres to the points needed by the enamel coating, extending the life of the tank. It is important for the magnesium anode rods used in boilers to be in compliance with European Standards. How Should the Resistance Test be Done in Boilers?
What is the Citric Acid Resistance Test in Boilers?
The citric acid test is done according to ISO 2722 standards. In boiler enamel tests, citric acid solution is applied for 20 minutes. MIT Boilers are of the highest class, AA, based on this test result.
What Should be the Sheet Quality in Boilers?
Ereğli TRKK 6222 cold-formed low carbon hot-rolled sheet is used in MIT Boilers. This sheet is resistant to aging, suitable for welding, has deep drawing properties, and is suitable for enamel coating used by single/double layer or single/double cooking. Also, S355J2 (ST 52-3) sheet is used in immersion galvanized accumulation tanks.
How is the Hot Water and Steam Resistance Test Performed with Boilers?
The test piece is subjected to a 48-hour test of boiling water and steam. At the end of this process, the enamel on the test part decreases slightly. According to European standards, the highest acceptable amount is 3.5gr/m². However, this amount is only 2gr/m² in MIT Boiler products.
How is Boiler Selection Made?
The most important criterion in selecting a boiler 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 includes the hourly amount of water needed and all water sources (taps) are calculated by being opened for 1 hour. In short, boiler selection should be made based on the hourly production value and the simultaneous usage factor.
What are the Advantages of Boilers?
Boilers can keep hot water inside for a very long time when they are not in use. While providing high efficiency with advanced technology insulation materials used, boilers are also protected from external influences. In boilers, the coils should be designed in a way that does not create cold regions. Rapid Boilers prevent the formation of cold regions through special coil designs and do not allow bacteria causing Legionnaires' disease to survive. In addition, with the titanium enamel coating, bacteria growth and corrosion are prevented.
