Improving precipitator performance

Are you looking for strategies to improve your precipitator performance?

Many factors can influence the performance of a precipitator but the cause can be identified by a thorough review of the current performance and a solution can then be recommended.

Precipitator modelling

We provide each customer with the best solution by: 
  • analysing available operational data to identify problem areas
  • providing a root cause analysis of performance issues
  • assessing coal quality issues
  • designing flow correction devices

 
Case study

High dust emissions were causing loss of generation in a base load power station. Operators had to regularly reduce load limit to meet emission limits.Total financial losses were in the order of $200,000 over a six-month period.

All aspects of precipitator performance were examined and a number of findings were reported. Recommendations were made to improve performance. Once implemented load ???

Our customers have enjoyed benefits including:
  • reduction of dust emissions which can also reduce plume visibility
  • reduction in pressure losses which can ease fan load requirements
  • identification of particular zones having reduced performance for inspection at the next outage
  • independent assessment and recommendation
  • accurate root cause diagnosis
  • improvement in ability to measure dust flows accurately

Case study

A power station's precipitators were performing so badly that the boiler often had to be run 20% below MCR to meet emission license limits.

An extensive testing and modelling program (including in-plant velocity measurements) was completed. Flow corrective devices were designed and tested in the model, then the optimal solution was fitted to the power station unit. No changes to the duct geometry were required, with modifications consisting of turning vanes and baffles.

The final design was tested in plant through velocity measurements taken during the return-to-service. Precipator performance was improved and could be run at MCR without exceeding emission licence limits.
