Absorption chillers, particularly those manufactured by BROAD, are well-regarded for their efficiency and environmental benefits. However, like any complex system, they are susceptible to certain issues. One common problem is the leakage in High-Temperature Generator (HTG) tubes and corrosion in Absorption chiller. This article explores the causes, impacts, and our innovation for HTG tube leakage and corrosion problem in BROAD absorption chillers.
BROAD Inovation for Leakage in HTG Tube
The working principle of BROAD’s fire tube Dry Back HTG structure can be succinctly described as: Exhaust in the tube, merged in the solution. This innovative design ensures that the exhaust gases are channeled through tubes submerged in the absorbent solution. This unique setup optimizes heat transfer and enhances the overall efficiency of the absorption chiller system.The fire tube Dry Back HTG structure in BROAD absorption chillers offers several benefits and some drawbacks. Understanding these can help in addressing issues such as HTG tube leakage effectively.
BROAD Advantages:
•Easily clean the soot, and heat efficiency is ensured. Almost same exhaust oulet temperature
•Soot corrosion is minimized which extends the lifespan of tubes.
•Easy leakage checks and maintenance
•Longer life span of chiller
Conventional Technology on HTG Structure :
Working Principle of HTG Structure for conventional absorption chiller is solution located in the tube and heated by exhaust outside, this technology have advantage for good thermal efficiency and have smaller size HTG, but have many disadvantages such as :
1. Soot can not be cleaned, thermal transfer resisted and thermal efficiency decreased;
2. Serious soot corrosion shortens the HTG life-span;
3. The leakage identification is difficult, once the leakage occurs, more leakage will happen and the HTG has to be replaced completely
4. High maintenance cost and short life span of chiller.
Conclusion
In conclusion, BROAD’s innovative fire tube Dry Back HTG structure offers a transformative solution to address HTG tube leakage and corrosion in absorption chillers. By channeling exhaust gases through tubes immersed in the absorbent solution, BROAD ensures optimal heat transfer, streamlined maintenance, and extended lifespan of HTG tubes. In contrast, conventional technology, while efficient in thermal transfer, faces challenges such as soot buildup and corrosion, leading to higher maintenance costs and shorter chiller lifespan. BROAD’s innovation represents a significant advancement in absorption chiller technology, promising enhanced efficiency, reliability, and longevity.
