"Internal cleaning of water tanks" Preventing problems caused by iron Chemical manufacturer

Invisible iron is undermining the performance of the boiler! Identify the cause through fiber scope investigation and work towards improvement.

To the chemical manufacturers, we would like to introduce a case where we visualized the internal condition of a boiler and conducted internal cleaning of the water supply tank. We received inquiries expressing concerns that the efficiency of the boiler seems to be declining, fuel consumption is increasing, and steam generation is poor. As we investigated further, the possibility arose that iron content in the raw water was gradually accumulating inside the boiler. First, we used a fiberscope to visualize the internal condition of the boiler. As a result, reddish-brown deposits were observed on the heat transfer surfaces and inside the piping, confirming the accumulation of iron. Additionally, to address the raw water side of the boiler, we conducted internal cleaning of the water supply tank. It became clear that iron rust was settling at the bottom of the tank, indicating that the root cause was the carryover from the raw water. [On-site issues] ■ The efficiency of the boiler seems to be declining. ■ Fuel consumption is increasing, but steam generation is poor. ■ Iron content may be related. *For more details, please download the PDF or feel free to contact us.
