Furnace Wall Blowers Optimization in Boile

Wall blowers are provided in boilers to clean the furnace wall deposits. They seldom finds its use in oil and gas fired boilers. Many methods are used for optimization of wall blower operation, like the manual method, heat flux measurement method, and the automated method. The interval period will depend on the area of deposition and the severity of deposition.
