Where are stationary soot blowers typically installed?

Stationary soot blowers are typically installed in convection zones because these areas are where flue gases are cooled significantly, often to the point where soot and other particulate matter condense and accumulate. The function of soot blowers is to inject steam or compressed air to dislodge soot buildup on heat exchange surfaces, improving heat transfer efficiency and maintaining operational efficiency of the system.

In convection zones, the heat exchangers are particularly susceptible to fouling from soot, which can lead to reduced thermal performance. Installing soot blowers in these areas allows for regular cleaning without needing to take the system offline, which is crucial for maintaining continuous operation and optimal heat transfer.

The other choices, such as secondary superheater banks, primary superheater banks, and reheater banks, while important components of thermal systems, are not typically where stationary soot blowers are placed. These components usually have different operational dynamics and might not experience soot accumulation to the same extent as convection zones.
