Description :

　　Manufacturing site of waste heat boiler

　　The smoke tube waste heat boiler consists of a drum, tubes, and a metal shell, with a compact structure and low metal consumption per unit heat transfer area. It can adapt to a wide range of media and operating conditions.

　　The boiler has good sealing performance and can operate under positive pressure.

　　Smoke tube waste heat boilers are inevitably contaminated by dust during operation. Excessive dust accumulation can cause an increase in exhaust gas temperature, affecting the heat transfer efficiency of the waste heat boiler. In severe cases, it can cause erosion and wear on the heating surface of the waste heat boiler, leading to production accidents such as boiler shutdown.

　　Adopting appropriate cleaning methods can improve the thermal efficiency of waste heat boilers and extend their service life.

　　The cleaning work of smoke tube waste heat boiler should not be underestimated. The heating surface of waste heat boiler is affected by many factors such as flue gas characteristics, temperature level, and heating surface structure. Only through boiler design and operation adjustment, the problem of ash accumulation on the heating surface of waste heat boiler cannot be completely solved.

　　The appropriate method should be chosen for cleaning the ash of the waste heat boiler in order to effectively reduce the accumulation of ash on the heating surface of the waste heat boiler and ensure its safe operation.

　　Ash cleaning method for smoke tube waste heat boiler

　　1. Steam cleaning

　　Steam ash cleaning of waste heat boiler uses high-pressure steam as the working medium, and blows the heat exchange surface with high-pressure steam by spraying through the ash blowing pipeline and ash blower, utilizing the impact kinetic energy of high-pressure steam for ash removal.

　　2. Acoustic soot blower for dust cleaning

　　The acoustic soot blower mainly uses compressed gas vibrating diaphragms or acoustic generators to convert the energy of compressed gas into sound energy of a certain frequency, and the sound waves enter the space area where the boiler accumulates dust during operation.

　　Using sound energy to cause dust particles to oscillate with air molecules, thereby preventing dust particles from accumulating on the heating surface and bonding between dust particles; Then use the power of the flue gas and the gravity of dust particles to bring it out of the boiler.

　　3. Air cannon dust cleaning

　　Air cannon dust cleaning uses the principle of air pressure balance to first store compressed air in a steel container, namely an air cannon. When the pressure inside the bubble reaches 0.4~0.8MPa, the air source is cut off through electric or automatic components; At the same time, open the exhaust port to allow compressed air to be sprayed in a predetermined direction at supersonic speed during braking, directly rushing into the ash accumulation area of the waste heat boiler.
