Quantification of radionuclides and associated radiological risk estimation of coal combustion residues from a South African coal-fired power plant
Background: Radionuclides occur in coal combustion residues, such as fly ash and bottom ash, which are by-products of coal combustion. They pose potential radiological risks to people present in the surrounding areas. Materials and Methods: Gamma spectrometry was performed to determine the radionuclide activity concentrations in a coal-driven power plant located in the Limpopo province, South A...
متن کاملIncreasing the Efficiency of Existing Coal-Fired Power Plants
Coal has long been the major fossil fuel used to produce electricity. However, coal-fired electric power plants are one of the largest sources of air pollution in the United States, with greenhouse gas (GHG) emissions from burning of fossil fuels believed to be the major contributor to global climate change. Regulations under development at the Environmental Protection Agency (EPA) would impose...
متن کاملCO2 CAPTURE OPTIONS FOR AN EXISTING COAL FIRED POWER PLANT: O2/CO2 RECYCLE COMBUSTION vs. AMINE SCRUBBING
The existing fleet of modern pulverized coal fired power plants represents an opportunity to achieve significant greenhouse gas (GHG) emissions in the coming years providing efficient and economical CO2 capture technologies are available for retrofit. One option is to separate CO2 from the products of combustion using conventional approaches such as amine scrubbing. An emerging alternate, commo...
متن کاملOxyfuel Coal Combustion Power Plant System Optimization
Oxyfuel-firing of a steam boiler is a low risk high-efficiency technique for CO2 capture in a power plant. Oxyfuel-firing can be readily adapted to a new power plant or to retrofit applications. Development and design of pulverized coal and circulating fluidized bed oxyfuel boilers and balance of plant equipment have been conducted to identify the required specific features, which will maximize...
متن کاملEnthalpy Calculation for Pressurized Oxy-coal Combustion
Oxy-fuel combustion is recognized one of the most promising available technologies that zero emission accomplishment may be in the offing. With coal burned under the pressure of 6MPa and oxygenenriched conditions, the high temperature and high pressure gaseous combustion product is composed of 95% CO2 and water-vapor, with the rest of O2, N2 and so on. However, once lauded as classic approach o...
