SMART Clean™ Intelligent Sootblowing is a closed loop control system that uses feedback from the heat exchanger, gathered in real-time during normal boiler operation, to effectively clean the recovery boiler heat transfer surfaces.
This system intelligently manages the sequence of sootblower operation through the use of a targeted cleaning strategy that saves steam by dynamically managing the sootblowing timing and flow. The SMART Clean™ system utilizes the real-time boiler data to detect build up in specific areas of the boiler. Once this build up has been identified, the system initiates a localized cleaning events to target the build up with the appropriate intensity. Comprised of an industry leading SMART Controls platform and real time Thermodynamic Modelling (TDM) feedback, the Clyde Bergemann SMART Clean™ system is the ultimate weapon to combat carry over and plugging problems while maximizing the heat transfer efficiency of the recovery boiler.
Clyde Bergemann has developed a numerical algorithm to filter the massive volume of data from the DCS and fouling sensors and convert it into boiler fouling information. The incoming data will be verified to ensure only quality information is used to control sootblower operation.
Once the analytical process from Step 2 is completed, the system operates selected cleaning equipment that will give the most heat transfer improvement impact for the boiler. Sootblower parameters such as blowing pressure, blowing speed, and zone by zone control are precisely directed according to the local cleaning requirements.
Once the particular cleaning devices complete their operations, the SMART Clean™ system evaluates the cleaning effectiveness and uses the information to continuously improve the sootblower cleaning performance.
The SMART Clean™ system will also use the existing flue gas draft differential pressures (DP) as a process variable and will calculate effectiveness for each sootblower on flue gas DP.
