Flue-cured tobacco (Nicotiana tabacum L.) is one of the most important commercial crops in the world. Genetic diversity studies provide estimates on the level of genetic variation among diverse materials that can be used in germplasm management, varietal protection, and flue-cured tobacco improvement. Amplified fragment length polymorphism (AFLP) analysis of 51 flue-cured tobacco cultivars prod...

Combustion of the municipal waste generates highly corrosive gases (HCl, SO2, NaCl, KCl and heavy metals chlorides) and ashes containing alkaline chlorides and sulphates. Currently, corrosion phenomena are particularly observed on superheater’s tubes. Corrosion rates depend mainly on installation design, operating conditions i.e. gas and steam temperature and velocity of the flue gas containing...

Project Description The EERC is performing fundamental research to understand mechanisms responsible for conversion of mercury to other chemical species within combustion and gasification flue gas. This research is imperative for development and validation of improved mercury emission measurement, monitoring, and control. Several tasks are devoted to understanding mercury transformations. Unbur...

Coaxial (wire-cylinder) electrodes arrangements are widely used for electrostatic deposition of dust particles in flue gases, when a high voltage is applied to immersed air and provide strongly non-uniform electric field. The efficiency filters mainly depends on the value distribution In this work, two-dimensional computer simulation was constructed study effect different voltages (20, 22, 25, ...

Algae are without doubt the most productive photosynthetic organisms on Earth; they are highly efficient in converting CO2 and nutrients into biomass. These abilities can be exploited by culturing microalgae from wastewater and flue gases for effective wastewater reclamation. Algae are known to remove nitrogen and phosphorus as well as several organic contaminants including pharmaceuticals from...

Adsorption of flue gases by single-wall carbon nanotubes (SWCNT) has been studied by means of Monte Carlo simulations. The flue gas is modeled as a ternary mixture of N2, CO2, and O2, emulating realistic compositions of the emissions from power plants. The adsorbed flue gas is in equilibrium with a bulk gas characterized by temperature T, pressure p, and mixture composition. We have considered ...

Arsenic is a poisonous element and its super mobility can pose major threat to the environment human beings. Disposed arsenic-bearing waste or minerals over time may release arsenic into groundwater, soil then food chain. Consequently, safe landfill deposition should be carried out minimize bleeding. Cement-based stabilization/solidification glass vitrification are two important methods for imm...

In this paper, an improved system to efficiently utilize the low-temperature waste heat from the flue gas of coal-fired power plants is proposed based on heat cascade theory. The essence of the proposed system is that the waste heat of exhausted flue gas is not only used to preheat air for assisting coal combustion as usual but also to heat up feedwater and for low-pressure steam extraction. Ai...
