Titanium® Intelligent Sootblowing (ISB) System

ISB systems are proven tools for increasing efficiency and maximizing unit output. Performance-based ISB systems, in particular, provide a cost-effective method of achieving unit cleanliness and performance by optimizing boiler heating surfaces while helping to reduce costs related to fuel usage, maintenance, sootblowing medium management, and tube failures from sootblower erosion. B&W’s Titanium® performance-based ISB system is powerful, yet easy-to-use and is built upon B&W’s extensive boiler design experience and the Diamond Power boiler cleaning experience.

Key Features

  • Boiler-performance model configured specifically to your boiler for accurate modeling of boiler performance and heating surface cleanliness
  • Expert system with flexible decision logic based on boiler performance and/or operational values
  • Automatically adapts sootblowing thresholds based on historical performance
  • Dynamic queueing of individual sootblowers based on calculated effectiveness
  • Multi-unit sootblowing coordination capability
  • Data historian for trending and analysis
  • Can operate without boiler model if needed

Potential Benefits

  • Improvements in heat rate and unit efficiency (see table on next page)
  • Reduction in overall sootblower usage while maintaining boiler performance
  • Reduction in tube erosion and thermal fatigue cracking
  • Reduced sootblowing-related O&M costs
  • Reduced temperature and spray swings
  • More consistent operation across load range and operating shifts
  • Reduced operator focus on sootblowing

Performance-driven sootblowing

The Titanium ISB system enables intelligent cleaning of your boiler based on calculated heating surface cleanliness. The system provides real-time analysis of slagging and fouling effects on local heat transfer and how that impacts overall boiler performance. This analysis produces effective cleaning strategies that are automated through the ISB expert system. The result is an industry-proven solution to boiler cleaning that optimizes system performance and provides quick returns on your investment.

Dynamic blower sequencing

The Titanium ISB system tracks the impact of every sootblower operation and uses this information to calculate sootblower effectiveness. When a heat transfer section needs cleaning, the Titanium ISB system uses the individual blower effectiveness and the last blower operation time to dynamically create a blower sequence. In doing this, the Titanium ISB system operates the sootblowers which have the highest cleaning impact more often while still making sure all areas of the boiler are kept clean.

Operation without model (optional)

The Titanium ISB system can be supplied without the boiler model for applications when it cannot be applied or is not desired. In this configuration, the expert system utilizes measured operational values such as temperatures and spray flows to make blowing decisions. All other Titanium ISB advanced features such as blower effectiveness tracking and dynamic blower sequencing are still used.
