WIC - Combustion Manager

Optimisation of combustion processes in waste-to-energy and biomass-to-energy plants can significantly improve plant reliability, availability and profitability.

The task of the combustion optimisation system is to stabilise the combustion process and thus stabilise the production of energy and the main process values like flue gas temperature and combustion air flows.

The development of WiC is based on more than 25 years of experience in combustion optimisation on plants from different suppliers.

Some simple combustion optimisation systems can provide stabilisation of steam production by implementing large oscillations in combustion air, especially in primary air.
These technologies may be very simple to use, but fluctuations in combustion air flow have significant disadvantages:

• Oscillations in the fan speeds (higher energy consumption - higher mechanical wear)

• Too much movements of the air dampers

• Increased fly ash

• Increased consumption of additives for flue gas cleaning

• Fluctuations in flue gas temperature

WiC uses real-time data processing, with far more data than traditional systems. WiC processes some 6500 functional diagrams instead of typically 50.

Every plant is unique and for every particular plant the control calculations must be done thoroughly. In the combustion management process, it is necessary to calculate many equations simultaneously in real time.

With its 6500 functional diagrams, WiC provides a quality and accuracy which is not possible to reach with conventional controllers and classic control strategies.
