As a manufacturer of Gas Waste Heat Boilers, we frequently receive inquiries from users regarding decreased heat exchange efficiency. These issues are often caused by minor problems during daily use, and with targeted troubleshooting and solutions, the equipment's normal heat exchange performance can usually be restored.
First, check for scaling on the heat exchange tubes. Smoke and impurities produced during gas combustion easily adhere to the surface of the heat exchange tubes, forming an insulating layer. If scaling is found, clean the tubes according to the equipment manual using a specialized descaling agent or high-pressure water to remove the dirt inside and outside the tubes, restoring the heat transfer capacity of the heat exchange surface.
Second, check for blockages in the flue gas passages. Excessive ash accumulation in the flue can obstruct flue gas flow, preventing sufficient waste heat transfer. In this case, open the flue inspection door and clean the internal ash to ensure smooth flue gas flow through the heat exchange area.
Finally, check the equipment's sealing. Air leaks in the boiler's flue, flanges, etc., will lower the flue gas temperature and affect waste heat recovery.Check each sealing point, replace aged gaskets, and repair leaks to ensure the equipment's sealing performance.
If the problem persists after self-troubleshooting, please contact our technical team. We will provide remote guidance or on-site repair services to help locate the problem and develop a solution, ensuring the Gas Waste Heat Boiler can stably perform its waste heat recovery function.
