Model based control of a small-scale biomass boiler

For this reason, a model based control strategy for small-scale biomass boilers was developed and successfully implemented in a commercially available system. Thereby, appropriate mathematical models were developed for all relevant parts of the furnace and connected to an overall model subsequently used for the control unit design.

Dynamic modelling of a CFB boiler including the solids

title = "Dynamic modelling of a CFB boiler including the solids, gas and water-steam systems", abstract = "Due to the widespread deployment of non-flexible renewable energy sources, an increasing trend is to use coal-fired boilers as support to the base energy production. High flexibility is usually required, and consequently, it is fundamental to be able to accurately predict and study dynamic behavior of the boilers.
