Özet:This study presents solar thermal application in the most energy consuming units of a cement plant located in Gaziantep, Turkey. Cement industry is the most important energy intensive and the second largest contributor to anthropogenic greenhouse gas emissions in the world which accounts for 5-6% of global CO2 emissions. Both material and energy flows are analyzed in the system for a conventional cement industry and a solar integrated one taking the most energy-efficient innovations into account. The whole system is modeled in TRNSYS and is simulated using data from the literature. The reason TRNSYS software is used is the availability of a considerable number of variable components required to simulate thermal and electrical energy systems. The aim of this work is to assess how much electricity can be supplied by solar resources and fossil fuel energy can be replaced using solar thermal energy. By using solar hybridization at the calcination and clinkerization processes in the cement production line, fossil fuel and CO2 emission flowrates are evaluated. According to the results, the studied solar-integrated systems produce approximately half of the electrical work demand of the plant and contribute to the reduction in annual fossil fuel consumption and CO2 emission by more than 10%.
