Surface and Bottom Blow-Off Valves
Surface and Bottom Blow-Off Valves: Automatic Blow-Off Systems in Steam Boilers
In industrial steam boilers, if the water is not handled correctly, the concentration of insoluble substances (TDS - Total Dissolved Solids) increases during steam generation. This can lead to serious problems in boilers and pipelines. ORFA Industrial Products Industry and Trade Inc. offers Surface and Bottom Blow-Off Valve solutions to prevent these problems and increase the efficiency of steam systems.
What is Bluffing and Why is it Necessary?
During the steam production process, insoluble substances (typically calcium and magnesium salts) form in the boiler. If these substances exceed a certain level, it can cause the following problems:
- Equipment failures
- It is carried away by the steam, increasing the conductivity of the condensate and causing energy loss.
- Corrosion and shortened boiler lifespan.
To prevent these problems, these substances that accumulate in the boiler need to be removed at regular intervals. This process is called "BLOWDOWN".
The Difference Between Surface and Bottom Bluffing:
Blowdown is performed in two different ways, depending on the type of substances that accumulate in the boiler:
- Surface Blowdown: If insoluble substances are in the liquid phase, meaning they do not sink or dissolve in water, they are automatically removed from the system thanks to the surface blowdown system.
- Bottom Blow-off: If insoluble substances are in the solid phase, meaning they settle to the bottom, they are removed from the system using a bottom blow-off valve.
Surface Bluffing System:
ORFA Industrial's surface blowdown system consists of the following components:
- 1 conductivity detector
- 1 transmitter
- 1 control valve
- 1 x PID conductivity control panel
Optionally, one plate heat exchanger and one recirculating pump can be added for the energy recovery system.
The Bottom Bluff System:
ORFA Industrial's bottom blowdown system consists of the following components:
- 1 timer
- 1 x fully stainless steel 3-piece actuator ball valve
- 1 pneumatic actuator
- 1 solenoid valve
Advantages of Surface and Bottom Blow-Off Valves:
ORFA Industrial's Surface and Bottom Blow-Off Valves offer significant advantages for steam boilers:
- It improves boiler safety and efficiency.
- It saves on labor costs.
- Suitable for all types of steam boilers.
Energy Recovery with Surface Blow-Off System:
ORFA Industrial also offers energy recovery possibilities with its surface blowdown system. By adding the necessary equipment to the system according to the determined TDS level, the saturated water removed by the blowdown valve can be used to heat the ship's feedwater using a plate heat exchanger. This can result in energy savings of 5-10% in fuel consumption.
Surface and Bottom Blow-Off Valve System Specifications:
- Working Pressure: Up to 16 bar
- Operating temperature: Up to 150°C
Surface and Bottom Blow-Off Valves Application Areas:
Surface and bottom bleed valves are used in steam boilers.
