Coal Plant Soot Blower Thermal Inspection (Pre-Automation Era)

01 The Problem

Before automated thermal monitoring existed, coal plants had to send an operator with a handheld pyrometer to walk past every soot-blower angle valve, twice a day, and write the temperature in a logbook. That left a 23-hour blind window every day in which a soot blower could be venting steam onto a boiler tube and slowly cutting through the wall — and nobody would know.

The Risk

Soot-blower valve internal leak causes continuous steam discharge between blowing cycles, eroding boiler tubes until rupture — tens of millions $in shutdown losses.

Detection Gap

Manual temperature-gun inspections left a 23-hour monitoring blind spot daily.

02 The OctosX Solution

We installed a Thermalpas pipe-clamp thermometer on every soot-blower angle valve — straps over the outside of the pipe, no welding, no drilling. The signal flows up to OctosX 24/7. If a valve that's supposed to be closed is venting steam, the temperature rise shows up immediately and the operator is paged.

Sensor & Edge

Thermalpas L-TYPE pipe-clamp thermometers install on every soot-blower angle valve outlet; OctosX monitors 24/7 and alerts immediately on continuous abnormal blowing.

03 The Outcome

This site was the precursor to the FPCC Mailiao project — the case that proved soot-blower monitoring was worth automating across an entire plant. Mailiao's full deployment now saves $12.85 million per year and paid back in 1.1 years. Without this earlier site, that project would never have been greenlit.

Field Detection

This is the precursor to the FPCC Mailiao automated system (see flagship case below) — annual savings $12.85M, 1-year payback.
