Analysis on Waterfall Tube Corrosion and Strength Calculation for Boilers Exceeding Service Life

Abstract:

Former USSR manufactured ΤΠ-230-2 type coal burning boiler has serviced for more than 369000 hours. The water fall tube burst caused by corrosion. The following examinations have been carried out , including macro-examination, metallographic analysis, tensile tests, inner and outer wall corrosion products and insulation materials analysis. Strength and remained thickness has also been calculated. Suggestions have been proposed to prevent similar explosions.
