Dust Monitoring Across the Steel Manufacturing Process

Lower downtime and better visibility across process stages

A large European steel producer

Challenge: repeated closures due to bag-filter failures

Solution: leak detection + continuous trend information

Continuous dust measurement supports filter condition assessment, process performance monitoring, post-ESP measurement and particulate emissions control in steel production.

The challenge

Steel production uses dust collection throughout cokemaking and sintering, furnace operations, conversion and finishing. Filter failures can release dust back into the process or towards emission points, while delayed detection can increase maintenance time, product losses and the risk of unplanned shutdowns.

A large European steel producer was shutting down three to five times per month because of bag-filter failures. Each shutdown lasted approximately two to three hours while maintenance teams identified and replaced the affected filter bags, resulting in around 10–15 hours of downtime per month and substantial annual cost.

The solution

The plant installed Sintrol Snifter monitors on each baghouse compartment to detect broken or deteriorating filter bags. Sintrol S303 trend monitors were added at outlet measurement points, and the monitoring system was connected to DustLog software.

Combining compartment-level leak detection with continuous trend information helped maintenance teams identify the affected baghouse more quickly and use cleaning-cycle behaviour together with dust trends to locate filter problems.

Results

Several hours of plant availability recovered each month.
The monitoring system shortened the time needed to identify filter failures and supported faster maintenance response.

  • Earlier detection of deteriorating and broken filter bags
  • Faster localisation of the affected baghouse compartment
  • Reduced downtime for filter maintenance
  • Better visibility into filtration performance

How it works

Sintrol’s probe-based dust monitors use Inductive Electrification technology. When solid particles contact or pass close to an insulated probe, they generate an electrical signal. Signal processing converts this response into a continuous indication of changes in dust levels for filter and process monitoring. Application-specific technologies are used where conditions require post-ESP field neutralisation or extractive measurement of wet and condensing gas.
