Influence Factors of Particle Diameter of Fly Ash during Pulverized Coal Combustion

Carbonation of Brine Slurried Size Fractionated Coal Combustion Fly Ash

Coal combustion by-products such as fly ash (FA), brine and CO2 from coal fired power plants have the potential to impact negatively on the environment. Reaction of CO2 with FA/ brine slurry can potentially provide a viable route for CO2 sequestration through formation of mineral carbonates. Fractionated FA has varying amounts of CaO which not only increases the brine pH but can also be convert...

Characterization of Nano-Ashes Generated during Pulverized Coal Combustion

Statistical Modeling of Constituents in Ash Evolved From Pulverized Coal Combustion

Industries using conventional fossil fuels have an interest in better understanding the mechanism of particulate formation during combustion since such is responsible for emission of undesired inorganic elements that directly impact the atmospheric pollution level. Fine and ultrafine particulates have tendency to escape the flue gas cleaning devices to the atmosphere. They also preferentially c...

Pulverized Coal Combustion: the Influence of Flame Temperature and Coal Composition on Thermal and Fuel

A laboratory combustor was used to investigate the factors that influence the conversion of fuel nitrogen in coal during coal combustion. Fuel NO was isolated by experimentation utilizing Argon/Oxygen/Carbon Dioxide mixtures as the oxidant, and care was taken to compare cases with air at matched conditions. For both well mixed and slowly mixed flame types, fuel NO contributed over 75% of the to...

Size Distribution and Trace Elements Contents of Coal Fly Ash from Pulverized Boilers

Pulverized coal boilers, commonly used in the power and heat-generating industries, constitute one of the most important sources of fine particulate matter (PM) emitted to ambient air. The evidence on airborne PM and its public health impact is consistent in showing adverse health effects at exposures currently experienced by urban populations in both developed and developing countries [1]. The...
