- Measurement of real-world PM10 emission factors and emission profiles from woodheaters by in situ source monitoring and atmospheric verification methods (PDF - 1,357 KB) | (RTF - 3,619 KB)
Executive summary
Domestic woodheaters are a major source of particle (PM10) pollution in Australia. Although most jurisdictions require woodheaters to comply with the Australian Standard for woodheater emissions (AS/NZ 4013), which includes a particle emissions limit of 4g per kg of wood burnt, there has been growing concern that even compliant heaters frequently do not meet this limit when operated in homes.
The key issue for policy development for air quality and environmental health is the contribution that woodheaters make to ambient concentrations of particulate and gaseous pollutants. A comprehensive understanding of the factors that influence the contribution of woodheaters to ambient PM levels involves at least three steps: verifying the heater's design characteristics, determining in-service emission PM factors for woodheaters, and quantifying the contribution of woodheater emissions to the ambient PM levels.
This project was commissioned to investigate the second and third steps by measuring in situ the emission rates of woodheaters for a small selection of households in the Launceston air shed in Tasmania. The specific objectives were:
- To provide an estimate of real-world emission factors for woodheaters in Launceston;
- To provide an estimate of wood- heater usage patterns and PM10 emission rates, and
- To assess whether CSIRO's transport model (TAPM) using in-service emission factors as determined through this study can accurately predict PM concentrations in the Launceston airshed.
