Advantages of flue-type waste heat boiler

　　Advantages of flue-type waste heat boiler:

　　1. The heat transfer efficiency is high, and the ventilation resistance is small, thereby saving the power consumption of the blower and the induced draft fan.

　　2. The heat transfer of the heat pipe relies on the phase change of the working fluid in the pipe. The two ends of the heat pipe are sealed by end caps. When one side of a heat pipe is perforated, only a small amount of working fluid in the pipe leaks out, but the hot fluid will not collude, so It also greatly reduces the possibility of air leakage.

　　3. The isothermal heat transfer characteristics of the heat pipe can ensure that the pipe wall temperature is maintained above the flue gas dew point temperature, so as to ensure that the heat pipe wall temperature can always be maintained above the flue gas dew point temperature, and the soot collected on the pipe wall is basically dry ash. When the flue gas flow rate fluctuates, it is taken away with the wind, forming a self-blowing process. At the same time, the heat pipe generates self-vibration during operation, which will shake off the ash and take it away with the wind, so that the entire heat exchanger is not prone to ash blockage.

　　4. By controlling the wall temperature of the flue gas end of the heat pipe heat exchanger, every point of each heat pipe of the heat exchanger can be above the dew point, thereby effectively avoiding sulfuric acid dew point corrosion during coal combustion.

　　5. The heat pipe heat exchanger is a static device with no moving parts, so there is no possibility of mechanical failure. Each heat pipe is relatively independent and can be repaired individually. Even if a small amount of heat pipe is damaged, it will not cause air leakage or significantly reduce the heat load, so that the reliability of the entire device is very high.
