Causes: Tube damage occurs due to the combination of thermal fatigue and corrosion. Corrosion fatigue is influenced by boiler design, water chemistry, boiler water oxygen content, and boiler operation. A combination of these effects leads to the breakdown of the protective magnetite on the ID surface of the boiler tube.Get Price
WASTE HEAT BOILERS AND STEAM DRUMS FEATURES Thin tubesheet, typically 1 inch (25 mm) thick, allows good cooling by the water on the rear face and as such, operates at lower temperature The tubes, which act as stays, are all at the same temperature, therefore, the tubesheet remains flat with no bending between tube holesGet Price
The double fire-tube boiler with water-cooled reversal chamber and burner penetration has a capacity of 70 t/h and pressures of 0.5 to 40 bar (g). As hot water boilers, the capacity is between 0,5 and 44 MW. The design temperature for the hot water boilers can be up to 200 ºC. To achieve better efficiency, an economiser can be installed.Get Price
Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.Get Price
