【 摘 要 】

Pulverized Coal Injection (PCI) used for the first time in 1850 by a French and a Belgian entrepreneur. Because of its increasing use, today, PCI has become the most traditional method decreasing the amount of coke consumption in high ovens. To increase capacity of coal burning process results an increase in ore/coke rate and a decrease in greenhouse gases (CO2, SO2, NOx) emissions, in terms of environmental effects, it constitutes significance. Life cycle Assessment (LCA) methodology is preferred in many studies as an evaluation method for economic and environmental effects used in production areas at present. Microalgae are important for the bio-mitigation of carbons/biological sequestration due to their property of under greenhouse gases and under flue gas effectively. Steel and iron industry is known for its high capacity of these kind of gases and microalgae pond integrated to a steel and iron industry can be a good way of struggling the unwanted impacts of these gases. Our project aims to develop a technology to burn Turkish coal and microalgae biomass resources and their mixtures at certain proportions under LCA. The results obtained in this study will be used to create a database on LCA evaluations in energy areas of Turkey.
