What should be done to heavy soot on the fireside of the tubes for optimal heat transfer?

For optimal heat transfer in a boiler system, it is essential to remove heavy soot that accumulates on the fireside of the tubes. Soot acts as an insulating layer that decreases the efficiency of heat exchange between the combustion gases and the boiler tubes. When soot builds up, it limits the amount of heat that can transfer to the water, causing the boiler to work harder and ultimately reducing its efficiency and increasing fuel consumption.

Regular maintenance, including the cleaning of soot from the fireside, ensures that the boiler operates at peak performance. This not only helps in maintaining a stable operation but also prolongs the life of the boiler and its components. Therefore, removing soot is a critical task that can't be overlooked in any boiler operation.
