Abstract
The flue gases from wood-fired domestic central heating boilers have been characterized. The following parameters were measured: - CO, CO{sub 2}, NO{sub x} and total hydrocarbons (THC), - tar and particulates, - twelve volatile organic compounds (VOC), - polyaromatic hydrocarbons (PAH), - chlorinated benzenes and phenols, - dioxins. Measurements were made on four boilers. Three were environmentally approved boilers with developed combustion technology, while the fourth was a traditional boiler, not environmentally approved. Measurements were made at nominal heat output when fired with dry and moist wood (moisture contents 16% and 28% respectively), and at 20% part load, when fired with moist wood. The tar emissions from the approved boilers were below the limit value, 30 mg/MJ, with the exception of one boiler when fired with moist wood. The traditional boiler showed tar emissions about 30 times higher than the approved boilers. The NO{sub x} emissions from the approved boilers were 100-140 mg/MJ. For the traditional boiler 60-76 mg/MJ was recorded. The emissions of Volatile Organic Compounds (VOC) were measured to 200-900 mg/MJ (12 selected VOC compounds) at nominal heat load from the approved boilers. At 20% part load, about ten times higher values were recorded. The traditional boiler emitted

At 20% part load the VOC emission was about the same as for the approved boilers. Dioxin sampling was conducted for one approved boiler. No detectable concentrations were found.
