Aug 12, 2009 · 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.
Boiler systems are classified in a variety of ways. They can be classified according to the end use, such as foe heating, power generation or process requirements. Or they can be classified according to pressure, materials of construction, size tube contents (for example, waterside or fireside), firing, heat source or circulation. Boilers are also

radiant heat of the furnace and/or the high temperatures of the flue gases. In Figure l, we are attempting to show that steam mass flow by itself is not the governing criterion for reducing tube metal temperatures. For the same tube O.D., we have indicated a thick wall tube on the right and a thin wall tube on the left. The thick wall tube will
microorganisms that may attach to the tube wall. Unfortunately, on the steam side of the tubing, copper transport to other locations due to this slow dissolution may cause other problems. The copper can deposit on the HP turbine blades or boiler tubes. When it deposits in the turbine (Figure 1), it can cause as much as 5% decrease in MW
