Fuel quality soft-sensor for control strategy improvement …

This paper aims to present an enhanced method for estimating fuel quality on a BioGrate combustion process and its use in a control strategy improvement. The dynamic model based method (DMBM) utilizes combustion power which is calculated using the oxygen consumption of the furnace and the energy balance of the boiler. The proposed method is tested with data from the industrial scale …

[PDF] Dynamic modeling of combustion in a BioGrate …

The development of efficient operation and control of a biomass boiler requires extensive knowledge of the combustion process inside the boiler furnace However, it is not possible to obtain the required knowledge through process measurements because the high temperatures and aggressive environment inside the furnace prevent taking accurate sensor readings. Instead, the process can be studied
