Influence of the Pellets Type on the Emission Characteristics of a Domestic Boiler

M. Rabaçal, U. Fernandes & M. Costa
This study evaluates the influence of the fuel type on the gaseous emission characteristics of a domestic boiler. To this end, pellets of pine and of furniture waste, both currently manufactured and commercialized in Portugal, and peach stones, made specifically for this study, were burned under two comparable boiler operating conditions and measurements of the principal parameters of the combustion process (flue-gas composition, excess air coefficient and boiler thermal efficiency) conducted under steady-state conditions.
