Oct 01, 2013 · It can be concluded that the reduction of the boiler tube thickness due to sulfuric acid dew point corrosion was the major cause of the water leakage from the boiler tubes. 3.3. Exposure test in the waste heat boiler. It was concluded from examination that the major cause of the boiler tube failure was sulfuric acid dew point corrosion.
Sulfuric acid is manufactured by the combustion of sulfur in air, S02' 02 and N2 enters a waste heat boiler where it is cooled to about 4l00 C. Before entering the converter, the gas is filte~ed to prevent ash from entering the converter and fouling the catalyst. Conversion
The gases are very hot and so are passed through heat exchangers (waste heat boilers). The gases are cooled to about 700 K and the water in the surrounding boiler pipes is converted into steam. In manufacturing one tonne of sulfuric acid, one tonne of high pressure steam is also produced.
Waste heat boiler and process gas cooler for nitric acid, caprolactam and hydroxylamine plants; Waste heat boiler for sulfuric acid plants; Turnkey thermal plants for the incineration of liquid and gaseous fuels and residues; Direct-fired steam generators for fuels such as natural gas, oil, hydrogen and low-carbon gases containing carbon monoxide
BOILER WATER TREATMENT AND TEST. By C/E Md. Azizur Rahaman Corrosion • Most metals used has been processed from there natural state and corrosion of metals may be considered as the returning of metal to its original form of metal oxide. • It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment.
