EMISSION CHARACTERISTICS OF BIOMASS COMBUSTION IN A DOMESTIC HEATING BOILER FED WITH WOOD AND VIRGINIA MALLOW PELLETS

摘要

The presented research was aimed at analysing the emission characteristics of a domestic heating boiler fed with Virginia mallow pellets (Sida her-maphrodita Rusby) and wood pellets available on the market. A 32 kW boiler with automatic fuel load adapted to wood pellets combustion was used in the research. The installation used in the research was a typical installation used to heat single-family houses. Timelines of changes in O2, CO, CO2, NO, NOx, and SO2 concentrations were registered at the boiler’s outlet throughout the study. Analyses of mallow pellets and wood pellets combustion in a boiler with automatic fuel load adapted to wood pellets combustion showed that CO, NO, NOX and SO2 emissions were higher during mallow pellets combustion.
