An Assessment of the Efficiency and Emissions of a Pellet Boiler Combusting Multiple Pellet Types

With sustainable energy being the key to reaching climate neutrality, utilization of non-wooden biomass is a necessity. This article compares emissions and efficiency combusting number types agrobiomass wood pellets. A comparison was made on moving grate pellet burner mounted in boiler, where flue gas had vertical flow via two pass heat exchangers with turbulization elements. Tests were conducted pellets (ENPlus), miscanthus straw pellets, sunflower husk corn stover During combustion, both met PN-EN 303-5:2012 emission requirements. Corn requirement nominal capacity. Sunflower are characterized by excessive CO particulate matter emissions. most problematic fuel from point view results this research. combustion there need decrease heating capacity due ash sintering.
