Abstract :

This article gives an overview of the first results of a long-term research on work regimes and behaviour of mineral matter in biomass boiler systems. As woody biomass is gaining importance as an energy source for electricity and heat, we need to investigate, with scientific methodology, the main problems that occur with biomass boiler systems. There are more researches on large power plants and lab scale batch boilers, but the results are often not applicable in case of small and medium size biomass boilers on which the research has been limited. In this article, two small-scale combined heat and power (CHP) plant industrial boiler systems are compared based on design and measured operating data. One boiler system uses grate firing and the other one uses bubbling fluidised bed technology. Both CHP plants have capacities of 2 MW electrical and 8 MW thermal. Previous research on the subject is reviewed, the set-up of the experiment is described and the results are provided and analysed. First conclusions on a more suitable technology for a mixed woody biomass fuel are drawn.
