Breakdown or an unplanned shut down of a boiler leads to tremendous monetary loss to the asset owners. To be specific water wall tubes act as veins of boiler operation and thus remain the most critical segment as the operational temperature ranges between 500 to 550 degree Celsius which leads to following failures: Boiler Waterwall Tubes and Condenser Tube Leakage in Tube failures are a cause of concern in boiler outage, contaminating boiler feed water due to condenser leakage leads to a large amount of damage. Condensers using brackish water for cooling in high pressure boilers will have to be maintained well to avoid any leakage of condenser tubes . Any leakage of condenser cooling water to the condensate leads to low pH Boiler tubes, Boiler steel tubes, Boiler steel pipeIn smaller boilers , the additional power generation tubes are separated in the furnace, while larger utility boilers rely on water injection tubes that make up the furnace wall to generate steam. High-pressure water tube boiler The hot water then rises into the steam drum.

Furnace wall construction . The problems associated with furnace refractory materials, particularly on vertical walls , have resulted in two water -wall arrangements without exposed refractory. These are known as 'tangent tube ' and 'monowall' or "membrane wall '. Boilers - University of Alabamatubes containing the water . The water tube diameter is much smaller than the shell diameter of a fire-tube boiler , so much higher pressures can be obtained, well over 2000 psi. The furnace and boiler tube area must be surrounded by a heavily insulated refractory wall to prevent heat transfer through the boiler walls .

Understanding the Boiler Furnace Wall Construction water wall construction for boiler water wall tubes in

Introduction Alternatives to Refractory Material Tangent Tube Monowall Membrane Boiler furnace is that part of the boiler where the temperature of the system reaches the highest. The furnace produces the necessary heat required by burning the fuel oil inside its small closed chamber. Because of the fuel combustion the internal temperature goes extremely high and for this rea it is necessary that the walls of the furnace are stacked with proper high temperature withstanding material.
