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 کاملPotassium behaviour during combustion of wood in circulating fluidised bed power plants
The behaviour of alkali metals, especially of potassium, during circulating fluidised bed combustion of wood-based fuels was studied experimentally in pilot-scale and industrial scale combustors. The fuels included willow, forest residue and waste wood co-combusted with paper mill sludge. As a result of this work, the main chemical and physical transformation mechanisms of potassium compounds i...
متن کاملDevelopment of Methane and Nitrous Oxide Emission Factors for the Biomass Fired Circulating Fluidized Bed Combustion Power Plant
This study makes use of this distinction to analyze the exhaust gas concentration and fuel of the circulating fluidized bed (CFB) boiler that mainly uses wood biomass, and to develop the emission factors of Methane (CH(4)), Nitrous oxide (N(2)O). The fuels used as energy sources in the subject working sites are Wood Chip Fuel (WCF), RDF and Refused Plastic Fuel (RPF) of which heating values are...
متن کاملNovel catalytic process for flue gas conditioning in electrostatic precipitators of coal-fired power plants.
One of the most important environmental protection problems for coal-fired power plants is prevention of atmospheric pollution of flying ash. The ash particles are typically removed from flue gases by means of electrostatic precipitators, for which the efficiency may be significantly increased by lowering the resistance of fly ash, which may be achieved by controlled addition of microamounts of...
متن کاملDesign of MPC for Superheated Steam Temperature Control in a Coal-fired Thermal Power Plant
A superheater is an essential part of the steam generation process in the boiler-turbine system. Reliable control of temperature in the superheated steam temperature system is necessary to guarantee efficiency and high load-following capability in the operation of coal-fired Thermal power plant. The PI and PID controllers are extensively used in cascade control of secondary superheated steam te...
