Unusual Refinery Boiler Tube Failures Due to Corrosion by

May 21, 2012 · So it passes from a drying tower, usually with counter current sulfuric acid (96-98%). 2. Assuming a water tube boiler, an understanding of heat exchange in radiant and convection section can be found in "Petroleum Refinery Engineering" by W. L. Nelson, 4th edition, McGrawHill 1958, Chapter 18. But this is devoted to tubestill heaters (furnaces

FAILURE ANALYSIS OF WASTE HEAT BOILER TUBES

Oct 01, 2013 · It can be concluded from the metallurgical investigations that the cause of the boiler tubes failure is the sulfuric acid dew point corrosion due to air leakage and cyclic temperature profile. Development of corrosion resistant materials is desirable to prevent sulfuric acid dew point corrosion in waste heat boiler tubes.

Sulfuric acid dew point corrosion in waste heat boiler

Boilers in acid plants are waste heat boilers cooling gases from sulphur furnaces, regeneration furnaces and between catalyst beds. Types of Boilers. There are basically two types of boilers in common use: 1) Firetube 2) Watertube. Firetube Boilers. In firetube boilers the hot gases are confined within tuibes arranged in a bundle within a shell.

heat recovery in sulfur,sulfuric acid plants

Mar 22, 1998 · In economizer tubes, sulfuric acid corrosion is an unlikely event because flue gas and tube temperatures are normally over the acid dewpoint. In this paper, the failure analysis of generator tubes (similar to the economizer of bigger boilers) of two small oil-fired subcritical boilers is reported.
