Abstract
Flame shape temperature distribution, CO2, and O2 concentrations in the pulverized coal-fired boiler at Seyitömer Thermal Power Plant are numerically investigated for real operating conditions. The numerical results are compared with the measured results to validate the model. It is observed that the calculated and measured temperature differences are less than 50 K. For both numerical analysis and measurements, a decrease in O2 concentrations and an increase in CO2 concentrations in the flame zone of the furnace are observed. The flame shape was numerically analyzed for various operating conditions of the burners. It is observed that the flame does not fill the boiler, narrows along the boiler, and disturbs the homogeneity of the temperature distribution for the cases when the opposite burners 2 and 5 are switched off separately. As a result, coal burners should be shut down during operation, considering proper flame formation. This study has provided important information to the literature for more efficient and environmentally friendly coal combustion in thermal power plants.
期刊介绍：
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
