Abstract:

The objectives of this project were:

To develop Self-Illuminated Video (SIV) and image analysis techniques to identify adverse combustion conditions in utility PF boilers.

To provide a number of quantifiable parameters from video images which can be used to evaluate flame stability and combustion.

To develop PC software to transfer key parameters to existing data logging systems in real-time.

To develop systems to transmit and integrate video data from a number of cameras, under actual boiler plant conditions.

To determine optimum video probe designs and locations for quantitative SIV on utility boilers.

All project objectives have been achieved. As planned, video capture and processing equipment was installed and tested on actual boiler plant early in the project and the results of practical experience used progressively to inform and refine developments.

This experience has confirmed the importance of proving techniques under actual PF combustion techniques. Work by Imperial on a number of other video projects involving observations in small-scale furnaces has shown that the technical challenges involved in acquiring satisfactory video data are much more severe in full scale plant. Different combustion-related phenomena are also encountered in practice.
