ZOZEN Boiler Solved Temperature Anomaly of Boiler Exhaust Gas

Boiler exhaust gas temperature is one of the important factors affecting energy saving. The high temperature of the boiler exhaust gas indicates that the heat released by the fuel combustion is not fully supplied to the water in the boiler, which results in a relatively large heat energy loss.

ZOZEN Boiler helps users resolve abnormal smoke exhaust temperature

Recently, a feedback on the abnormal temperature of exhausted gas was received by the after-sales department of ZOZEN Boiler. The energy-saving device of ZOZEN gas-fired boiler can control the flue gas temperature below 60℃, which leads to the boiler thermal efficiency up to 98%.

Previously, a research institute purchased a set of ZOZEN WNS series gas-fired steam boiler. The boiler ran smoothly for two years, the user spoke highly of the boiler. But recently, the user found the boiler was unable to operate normally due to the exhaust gas temperature was too high.

The technician of ZOZEN Boiler arrived at the site, they checked the boiler operation record and found no other abnormalities except the high temperature of exhaust gas. The temperature showed 144℃ in shutdown state, which was obviously unreasonable. After the inspection of the boiler system, the technician determined that the transmitter module of temperature sensor on the economizer was damaged, resulting in abnormal temperature display.

Sensor damage is a common cause of abnormal temperature of boiler exhaust gas, so it only needs to replace the corresponding components. With the help of ZOZEN after-sales team, the user replaced the damaged part in time, and the exhaust temperature on the boiler control display returned to normal immediately.  At the same time, the technician of ZOZEN Boiler carried out a systematic inspection of the boiler, re-set the gas boiler control procedures, in order to achieve better operating conditions.

It is worth noting that there are many reasons for the abnormal temperature of the boiler exhaust gas. Such as insufficient combustion burner, dust deposition on inner wall of smoke tube; circulating pump not started, water temperature is too high, etc., will lead to the boiler exhaust gas temperature exceeded.

Users do not have to worry too much when they encounter such problems. On the one hand, they need to observe the boiler operation at any time and stop the boiler when necessary. On the other hand, they may need to contact the manufacturer in time and wait for the professional serviceman to find out the cause on the spot before making a solution. In addition, during the daily use of gas-fired boilers, users should abide by the safety operation regulations and master the operation skills of boilers.
