Modeling of a Small-Scale Biomass Boiler as a Basis for Model Based Control Strategies

M. Gölles, S. Reiter, T. Brunner, N. Dourdoumas & I. Obernberger
Currently the full potential for low¬ emission operation at high efficiencies of small¬scale (residential) biomass boilers for space heating cannot be exploited since there is still the need to optimize the plant control systems. They are currently based on decoupled control circuits with linear controllers. But a small¬ scale biomass boiler is a strongly coupled and nonlinear system. Therefore, the full potential in terms of low¬ emission operation and high efficiency can not be utilized...
