Corrosion Prevention in Boilers by Using Energy Audit Consideration

Abstract:

Marun's petrochemical boilers after four years was auditing by a team consist of different experts. Result of that audit was showing over design consuming of excess air and fuel which it cause low efficiency of working that evaluated by a program in excel application. For next step by using Fluent &Gambit software, boiler analyzed and it appeared that some of primary rows of boiler bank tubes caused overheating and after report, because of exceed requirement of steam for operation, boilers operated without stopping. So after short period some of boiler tubes ruptured and this failure continued until were decided to repair and replace overheated tubes with new ones and by calibrated and changed instrument logic, correction control loops, excess air set and it caused better efficiency, decrease polluted environment gas, prevention of corrosion in tubes, decrease fuel consumption and turning off one of boilers by receiving high efficiency of others boiler. So by using designed excel program for boiler process, condition monitoring perform monthly.
