The paper summarizes EPA-sponsored large-chamber characterizations from unvented kerosene space heaters. EPA's AEERL has been investigating emissions from kerosene space heaters since 1984. The focus of EPA's efforts has been on evaluating organic and particulate emissions from those sources and the development of emissions factors for these pollutants. To date, 26 makes and models of kerosene space heaters have been tested in the program. The tests have covered a variety of use conditions in different test environments, including hoods, chambers, a test house, and the 'field.' Objectives of the first study in 1984 were to determine the more appropriate method (i.e., hood vs. chamber) of evaluating emissions from kerosene heaters, and to characterize the organic and particulate emissions from two such units. The work concluded that, except for particulate measurements, the testing methods were basically the same for all pollutants. However, the larger volume of the chamber permitted particle formation similar to that anticipated to occur in indoor environments. Consequently, chambers were selected as the method of choice for further studies.
