How high is Yangzhou chimney?

In the past, the big chimneys in cities were generally more than 50 meters.

According to the technical requirements of general coal-fired boilers, the chimney should not be less than10m. However, there is no specific requirement for gas boilers, and it is generally required to exceed the building height. If it is too high, the outlet flue gas temperature will be too low, which will affect the power and life.
