ISWA'15 World Congress, Antwerp

Dublix has been selected to present its optimization technology at the ISWA World Congress 2015, Antwerp, Belgium, 7-9 September 2015.

Dublix will present its concepts for optimization of WtE (Waste to Energy) combustion plants.

For many years the Real-time Control of industrial processes has revolved around the use of the traditional PID (Proportional-Integral-Derivative) controller. As mathematical modeling techniques have developed and computational power at the process control level has improved, techniques have been developed over the last 20 or so years looking to improve the control of continuous processes.

Terms such as MPC (Model Predictive Control), High Level Control, Expert System and Fuzzy logic are often banned by suppliers of automation equipment but when implemented successfully, the described methods can have a significant impact on the profitability and efficiency of any industrial process.

Dublix applies its FuzEvent® system for combustion stabilization on WtE plants.

It is not uncommon to achieve anything between 0.5 and 5% improvement in for example boiler efficiency, steam generation and stability, plant capacity, overall energy production, and emissions/chemical reductions. The payback time will in many cases be only a few months.

Due to the nature of the WtE process - the fluctuation in heat values and other variations in the fuel, the waste, the required emission limits, the process equipment limitations - many WtE plant operators want to improve the combustion performance, either by upgrading its existing control system or by installing new advanced combustion control facilities, but unfortunately the obtained results are not always successful due to a number of reasons.

When introducing advanced combustion stabilization technology such as FuzEvent® or similar tools, it provides a different method to control the plants, the system activating special control strategies, when the situation so requires. It is a challenging discipline to implement these new advanced functions in an existing organization already used to handling the combustion process and coping with its often special behaviour. Some operators therefore tend to be reluctant to participate in such optimization projects, basically because it is questioning the current mode or regime of operation.

Experience however shows that specialists cannot do the job without strong support from the operators with hands on experience, the optimization specialist needs to receive maximum feedback from the operators during the commissioning and test phases.

During the ISWA'15 World Congress Dublix will address the process and the methods to be applied during the implementation; we would like to discuss how to obtain the crucial acceptance by the operators of the need for alternative techniques/methods implemented in the optimization project.

Dublix will be represented by our Sales Director Asger Danielsen. Please contact us for more information and if you want a meeting during the ISWA'15 World Congress.
