Failures in Ammonia Plant Vertical Waste Heat Boilers-Potential Causes & Remedies
The authors were involved in investigations of corrosion problems in Ammonia plant Waste Heat Boilers that had in common, that deposits on the water/steam side were noticed/involved in all cases.The paper will give a brief description of the operating conditions for different designs and shortly resume cases of corrosion in synloop Waste Heat Boilers (WHB) concerning location of the damages. The potential sources of deposits, the analysis of potential causes and the remedies to avoid premature failure will be discussed. Oxidation scale generated during Post Weld Heat Treatment and remedies to further boiler failures will be discussed based on actual inspection results.
