Emissions by the combustion of wood, fuel oil, coal and gas.

The emissions were measured in a steam boiler with a thermal output from 28 to 70 kW. To get the real data the emissions measurements were not taken in testing laboratory but in place. Analyses were made of the standard components as O2, CO2, CO, NOx, SO2, TOC and dust, also some alcohols, aldehyds, acids, cyclic, polycyclic and aromatic hydrocarbons.
