Sootblow optimisation saves energy, CO2 and money. Sootblowing is inevitable, why not chose to optimise it?

Sootblowing too early leads to a loss of steam and energy. Sootblowing too late leads to losses due to bad heat exchangers’ conditions. Optimising the timing of sootblowing solves the dilemma. 

Optimisation of total costs means optimising the energy balance, while taking into account fuel costs and electricity or heat revenues. Our algorithms are based on a multi-dimensional real time optimisation. In addition, we developed a calculation method for real-time monitoring of heat exchanger efficiency.

The algorithms were developed with funding from the Flemisch agency of innovation and entrepreneurship (VLAIO). Patent pending.


By means of a detailed heat- and mass balance of the installation, we derive the costs for the energy lost through inefficient heat exchangers. By comparing these costs with the cost of performing a sootblow, an optimum timing for sootblowing is proposed.

We worked with Entras from the development of our business case to the contracting of our asset.

Value creation is their leading principle, this during each phase of the project.
