Old boilers – high emissions | Airclim

For example, under normal conditions, emissions from old wood boilers were between five and ten times higher than those from modern wood or pellet boilers. The study also showed that reducing output – burning too little wood and throttling back the air supply to achieve longer burning times – results in poorer combustion and higher emissions.
