Emissions from unvented kerosene heaters.
Vapor-phase polynuclear aromatic hydrocarbon (PAH) emissions from unvented kerosene heaters were measured. During normal heater operations, tri- and tetra-cyclic PAHs were observed, whereas penta-, hexa- and hepta-cyclic PAHs were not observed. The convective-type heaters had significantly less PAH emissions than the radiant-type heaters. Emissions of particulate soot were also measured. The soot did not contain PAH. A two-compartment model is presented and used to simulate heater operation in a home. Certain simulated PAH levels are similar to that measured in the ambient air of large cities.
