Design of thermal power plant modernization and rehabilitation model for the new market demands and challenges

Abstract

The article presents the model for the rehabilitation of existing conventional thermal power plants in order to lower the consumption of fossil fuels. Instead of them, the model uses an alternative energy source - sun irradiation. The proposed rehabilitation model is theoretically calculated and designed. The model in the software environment Matlab Simulink was developed, based on previous calculations and determined parameters. In this article, it is presented the combination of Clausius - Rankine process and solar central receiver system. The model enables simultaneous calculations of exit model parameters for the complete model, based on predetermined entering parameters of the model.

First-principles study of calcium-based sulfur fixers and their products

“…The investment and operating costs of this method are both low, and it has been widely used. However, the limestone furnace decomposition and sulfur fixation technology have their own shortcomings [5][6][7][8][9][10]: (1) The decomposition time of limestone in the furnace is longer, and the organic sulfur volatilized in the coal is shorter, resulting in the decomposition of calcium oxide and the decomposed sulfur. Oxides cannot match the reaction well, which affect the efficiency of sulfur fixation in the furnace, resulting in a large concentration of sulfur oxides in the flue gas.…”
