Maximize power plant production and profit

FOULING MANAGEMENT

Run your sootblowing cycles at the right time, not just any time.

Knowing the right sootblowing interval of your boiler is challenging, yet important:

  • Too frequent sootblowing may cause accelerated wear in boiler tubes and uses excess steam.

  • On the other hand, lack of proper sootblowing allows fouling to degrade heat exchanger performance.

This problem can be solved with Fouling Management, which enables you to optimize boiler performance with adaptive sootblowing cycles. The operator can monitor performance of heat exchangers from heat transfer indexes, and he/she is also informed of the optimal timing for the next sootblowing.

Benefits

Increase boiler efficiency

By knowing the right sootblowing interval of your boiler you can increase it's efficiency and profit level.

Sootblowing too frequently easily causes accelerated wear in boiler tubes thus adding maintenance costs. Sootblowing also uses steam and any unnecessary sootblowing is directly out from the total production.

On the other hand, lack of proper sootblowing allows fouling to degrade heat exchanger performance. This also results in unnecessary lost production capacity.

The problem can be solved with Fouling Management, which enables you to optimize boiler performance with adaptive sootblowing cycles. The operator is informed of the optimal timing for the next sootblowing. The indexes and optimal timing are continuously calculated from actual boiler conditions with machine learning algorithms. Heat exchangers performance can be monitored online with the use of heat transfer indexes for each heat exchanges.

Avoid unnecessary sootblowing

Sootblowing too frequently easily causes accelerated wear in boiler tubes thus adding maintenance costs. Sootblowing also uses steam and any unnecessary sootblowing is directly out from the total production.

Reduce lost steam

Sootblowing also uses steam and any unnecessary sootblowing is directly out from the total production.

Reduce wear of components

Sootblowing too frequently easily causes accelerated wear in boiler tubes thus adding maintenance costs.

Unified operations between shifts

When fixed sootblowing schedule is in use the operators all follow the same routine. However, this is usually far from optimal and demands for more flexible and adaptive scheduling. Fouling management provides the essential insights about the heat transfer indexes and guidance for the optimal time for next sootblowing. This unifies the operations between operators – every operator uses the same knowledge and follows the best practices the same way.

Features

Adaptive sootblowing cycles

Fixed sootblowing schedule is usually far from optimal and would require adaptive sootblowing cycles and scheduling. Fouling management optimizes the cycles by ensuring perfect heat transfer index for each heat exchanger while minimizing the sootblowing for each one of them.

Individual heat transfer indexes

Each heat exchanger is analyzed individually and the total heat transfer is optimized.

Optimal time to next sootblowing

The optimal time to next sootblowing is calculated for heat exchanger individually. Depending on their controls and grouping the system displays which heat exchangers are to be cleaned and when.

Boiler power trend

Boiler power trend provides the operator information about the earlier power levels of the boiler. This provides additional insights about fouling.
