چکیده
Mazot has negative environmental effects compared with gas fuel. Mazot is employed as a secondary fuel in some cement plants located in Iran. Besides, replacing Mazot with natural gas (NG) not only reduce pollutant emission, but also save huge amount of money for those companies. Hormozgan Cement Plant operates two clinker kilns, each comprises of 5-stage FCB inline calciner kiln at a typical raw meal feed rate of 225t/h. The calciner burns 86% natural gas and 14% Mazot. In the present study, we will show how computational fluid dynamic (CFD) can be aided us to simulate the calciner of the cement plant and propose a cost-effective solution to replace Mazot with NG. At the end, it is demonstrated that not only the plant can operate with 100% NG, but also its production rate can increase with the new proposed configuration. Furthermore, the specific fuel consumption rate reduces. After this simulation, one of proposed cases implemented on the plant and results showed that by removing Mazot, production rate remained constant and specific heat consumption reduced as the simulation results.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
