In the present investigation, the concentrations of polycyclic aromatic hydrocarbons (PAHs) associated with PM2.5, PM10 and dust particles emitted from two tea processing industrial units were studied that uses high-sulfur coal as their energy source. A total of 16 PAHs (viz. naphthalene (Nap), acenaphthene (Ace), acenaphthylene (Acen), phenanthrene (Phe),(More)
The objective of this study is to determine the concentrations of gaseous species and aerosols in and around a non-recovery type coke making oven using high sulphur coals. In this paper, physico-chemical properties of the feed coal sample are reported along with the collection and measurement of the emitted gases (SO2, NO2, and NH3) and aerosol particles(More)
Bio-energy is now emerging as a future source of energy. Pyrolysis is one of the main thermo-chemical processes that can provide a useful and valuable bio-fuel such as bio-oil and bio-char. Bio-oil was produced from an undesired bio-weed named Ipomoea carnea by thermal pyrolysis at a terminal temperature range from 350 to 600 °C with a heating rate of 10(More)
Studies on coal-derived nanoparticles as well as nano-minerals are important in the context of the human health and the environment. The coal combustion-generated aerosols also affect human health and environmental quality aspects in any coal-fired station. In this study, the feed coals and their combustion-generated aerosols from coal-fired boilers of two(More)
