Project: Develop Advanced Image-processing
Algorithms to Control the Cleaning of Heat-transfer Surfaces
in Energy-intensive Industrial Processes
Overview of R&D project sponsored by Washington Technology
Center, conducted in partnership with the University of
Washington:
- Develop an automated imaging system that can be used in
hostile process environments to provide information to
operators about abnormal or undesirable conditions within
kraft boilers
- Target detection of fouling in convection exchanger areas
of kraft boilers
Benefits of this technology include:
- Provides a means to automatically measure extent of
deposits on boiler tubes during normal boiler operations
- Enables tuning of the cleaning process in order to focus
on those areas where deposits are forming and de-emphasize
areas where tubes remain clean
- Reduces the amount of steam used for defouling, resulting
in energy savings, reduction of pollutants and greenhouse
gases, and reduced operating costs for the pulp and paper
industry
- Allows the operation of recovery boilers for longer
periods between shutdowns
Applications of this technology include:
- Kraft boilers used in the pulp and paper industry
- Power boilers
- Waste-to-energy boilers
