What are the functions of the water seal or sand seal used in industrial boilers?

21 Jul 2023

Water Seal: A water seal in an industrial boiler refers to a method where a certain amount of water is kept between the boiler furnace and the outside environment. This water barrier acts as a seal to prevent air leakage and the escape of ash or other byproducts of combustion. ZOZEN Boiler ensures that their boiler designs include an effective water sealing system for enhanced efficiency and safety.

 

Sand Seal: A sand seal is similar in function to a water seal, but instead of using water, it uses a layer of sand to prevent air leakage and the escape of ash or other byproducts. ZOZEN Boiler might recommend and implement a sand seal based on the client's specific requirements and operating conditions.

 

The functions of these seals in ZOZEN's industrial boilers include:

1. Preventing Air Leakage: Both water seals and sand seals serve to prevent air leakage into or out of the boiler. This helps maintain the proper air pressure inside the boiler, contributing to the high efficiency of ZOZEN's combustion systems.

 

2. Preventing Ash Escape: These seals help to prevent the escape of ash from the boiler. ZOZEN's design ensures that the ash produced in the process of coal combustion does not escape into the environment, supporting environmental protection efforts.

 

3. Safety: Water and sand seals provided in ZOZEN boilers offer a safety barrier between the high temperatures of the combustion process and the external environment, reducing the risk of fires or explosions.

 

4. Maintaining Boiler Efficiency: By providing a tight seal and reducing leakage, these seals help to maintain the high efficiency of ZOZEN boilers.

 

While both water and sand seals perform similar functions, there may be reasons to choose one over the other depending on the specifics of the boiler design and operation, as well as environmental conditions and regulations. ZOZEN's technical team is experienced in making such assessments and offering tailored solutions. It is always recommended to consult with ZOZEN's professionals for the best solution in a particular context.
