In boilers, efficient water injection is a necessity for the proper functioning of this steam generator. The boiler water injector is responsible for ensuring the water supply in the absence of external energy sources. It is worth mentioning that this is a requirement present in NR-13.
In this context, among the water injectors offered for the national market, the MBX water injector for boilers deserves great attention, mainly due to its construction features and quality standard.
Understand the importance of water injectors for boilers and learn about the main differences in the device manufactured by MBX.
Functions of a water injector for boilers
In a boiler, water feeding means replenishing the water that is transformed into steam by the boiler.
Typically, this water supply to the boiler is done by high-pressure centrifugal pumps that are driven by electric motors.
However, if this replacement does not occur, the amount of water inside the boiler tends to decrease, consequently the tubes overheat, causing damage to the entire structure of the equipment. This fact increases the occurrence of possible and serious accidents.
To avoid this occurrence, the use of a water injector for boilers becomes mandatory and a requirement of Regulatory Standard number 13 (NR-13).
Its function is to supply water to the boilers in cases where the electrically powered water pump stops.
Operation of the water injector for boilers
In the absence of power, the injector will be immediately put into operation and will use the steam generated to inject water into the boiler. This ensures the operational safety of this equipment.
The injector uses the process steam itself to inject water into the boiler, through the venturi system. Given this pressure differential, these injectors do not require external energy sources to operate.
This feature meets the requirements of regulatory standard NR-13, as an independent water supply system for non-atomized solid fuel boilers or suspended combustion.
Furthermore, because they have no moving parts inside and do not depend on electrical energy, water injectors for boilers are high-performance and versatile equipment, ensuring safety in the use of the equipment.
Technical data and advantages
MBX is entirely focused on research and manufacturing of innovative products, serving the entire national territory. We manufacture high-performance, high-quality products for companies in all segments.
For these companies, MBX manufactures an excellent water injector for boilers. MBX injectors promote the feeding of water into boilers with great efficiency, whenever necessary, mainly because they present some very important differentials.
The ends of the MBX injector body (cold water inlet, steam inlet and water outlet for the boiler) are forged connections (welding tips) prepared to be welded to the pipes with great efficiency.
This condition facilitates handling for assembly and disassembly and offers greater safety in installations. It also eliminates the occurrence of leaks in connections.
These are technical data of the water injector for MBX boilers
- Manual operation;
- It has back-pressure safety valves;
- Uses steam from the boiler itself;
- Operating range (2.8 kgf/cm² to 9 kgf/cm²);
- Flow rate from 600 to 1,400 l/h;
- BSP input and output connections;
- Adjustment rod with aluminum handle;
