SELECTION OF LIQUID FUEL TYPE FOR BOILER ROOM Проведен сравнительный анализ основных видов резервного топлива для котельных, включая мазут, дизельное топливо и сжиженные углеводородные газы. Проанализированы основные технологические аспекты и особенности построения топливных хозяйств. Рассмотрены экономические аспекты использования различных видов резервного топлива. Оценены тепловые и стоимостные затраты на хранение и сжигание топлив. Выполнен расчет выбросов в атмосферу вредных веществ, включая диоксид азота, оксид азота, оксид углерода, бензапирен, диоксид серы, сажу. Определены массы выбрасываемых веществ, их концентрации в долях ПДК, расстояния, на которых наблюдается максимальная концентрация выбросов. Обоснована перспективность использования сжиженных углеводородных газов и технологии «Propane-Air». The article presents a comparative analysis of the main types of reserve fuel for boilers, including fuel oil, diesel fuel and liquefi ed petroleum gases. The main technological aspects and features of construction of fuel farms are analyzed. The economic aspects of the use of diff erent types of reserve fuel are considered. The thermal and cost costs of fuel storage and combustion are estimated. The calculation of emissions into the atmosphere of harmful substances, including nitrogen dioxide, nitrogen oxide, carbon monoxide, benzapyrene, sulfur dioxide, soot. The masses of emitt ed substances, their concentration in fractions of MPC, distances at which the maximum concentration of emissions is observed are determined. The prospects of using liquefi ed hydrocarbon gases and «Propane-Air» technology are substantiated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
