Toxicity of carcinogenic pahs in boiler flue gases thermal capacity up to 1 Mw

Abstract

THE PURPOSE. In accordance with the new requirements of domestic environmental legislation, technological principles of state regulation of the negative impact of energy enterprises on the environment have been introduced. The established principles of environmental protection activities provide for technological regulation of emissions based on the introduction of the best available technologies, as well as differentiation of state regulatory measures to ensure the environmental safety of thermal power facilities. Within the framework of the current environmental legislation, it is shown that it is necessary to determine emission standards for highly toxic substances that have carcinogenic properties. The main representatives of carcinogenic PAHs found in the flue gases of boilers of low power up to 1 MW are considered.METHODS. The research methods included the generalization of experimental data and thecalculated assessment of the content of carcinogenic emissions, including benz(a)pyrene in the flue gases of boilers using statistical data processing methods.RESULTS. The necessity of taking into account the contribution of the harmfulness of carcinogenic PAHs in the system of industrial environmental control at thermal power facilities during the operation of low-power boilers is determined.CONCLUSION. The results of the study can be used at energy enterprises to implement the requirements of the new environmental legislation in terms of technological regulation of carcinogenic emissions, including for the development of measures to improve environmental performance indicators.
