Description:
The report goes results of (1) a comparison the hood and chamber techniques for quantifying pollutant emission rates from unvented combustion appliances, and (2) an assessment of the semivolatile and nonvolatile organic-compound emissions from unvented kerosene space heaters. In general, the techniques yielded similar emission- rate results for CO, NO, and NO2. However, when differences were observed, it was concluded that the chamber- technique value was more realistic because it allows the oxygen level supplied to the appliance to decrease as it would in residences. A well-tuned radiant heater and a maltuned convective heater were tested for semivolatile and nonvolatile organic pollutant emissions. Each heater was operated in a 27 cu m chamber with a prescribed on/off pattern. Organic compounds were collected on Teflon-impregnated glass filters backed by XAD-2 resin and analyzed by gas chromatography/mass spectrometry. Pollutant source strengths were calculated using a mass-balance equation. The results show that kerosene heaters can emit polycyclic aromatic hydrocarbons (PANs); nitrated PANs; alkyl benzenes; pentachlorphenol; phthalates; hydro naphthalenes; aliphatic hydrocarbons, alcohols, and ketones; and other organic compounds, some of which are known mutagens.
