DETAILS OF INTERESTING CLAIM - I mia

The presence of steam would weaken the acid concentration that in turn would cause extensive corrosion throughout. Attempts to purge the steam from the system included closing of dampers, depressurizing the boiler, opening vents and blowing dry air through the plant. Before the air blowers could be turned on however, it was necessary to cool the HRS acid tower via the acid circulating pumps.

Low Temperature Corrosion in Boiler and Its Prevention

Boilers generating steam for use in power generation and process power plants use different type of fuels. These fuels contain sulphur to differing percentages. The higher the percentage of sulphur, the higher will be the risk of cold end corrosion in the boiler. The sulphur in the fuel during combustion gets converted to sulphur dioxide.
