Problems with 20,000-ton sulfur waste heat boilers
Thread Content
After operation began, regular wastewater discharge inspections revealed that the wastewater from the waste heat boiler was red-colored – could this be due to corrosion? How should it be adjusted?
No. Add chemicals as normal, and carry out regular sewage discharge more frequently.
It is caused by rust or impurities in the pipes during the initial operation period; what you need to do is ensure proper dosing of chemicals, increase the frequency of regular blowdowns from the boiler, and maintain the quality of the boiler water and steam!
