Mutagenicity in Emissions from Coal- and Oil-Fired Boilers

The history, genotoxicity, and carcinogenicity of carbon

Oct 01, 2014 · Also in 1983, Alfheim et al. demonstrated that emissions of mutagens from coal- and oil-fired boilers are low when the boilers are operated at optimal conditions. For samples from three of the plants investigated, no mutagenicity could be observed with the Salmonella /microsome assay; only one remained non-mutagenic when tested with V79

1.3 Fuel Oil Combustion

The major boiler configurations for fuel oil-fired combustors are watertube, firetube, cast iron, and tubeless design. Boilers are classified according to design and orientation of heat transfer surfaces, burner configuration, and size. These factors can all strongly influence emissions as well as the potential for controlling emissions.
