| کاهش آلودگی هوا در هنگام مصرف سوخت مازوت از جمله نیازهای ضروری بخش نیروگاهی برای جلوگیری از بروز آسیب‌های زیست محیطی می‌باشد. از طرفی آلودگی‌های سمی موجود در هوا با نزولات جوی ترکیب شده و باران‌های اسیدی به وجود می‌آورند، لذا اثر تخریبی آنها زیاد می‌گردد. پژوهش حاضر به بررسی ویژگی‌های مکانیکی و متالوژیکی رسوب‌های حاصل از احتراق سوخت مازوت بر روی مشعل و لوله‌های سوپر هیتهای نیروگاه ایرانشهر و همچنین میزان آلاینده‌های آن می‌پردازد. سپس مطالعات و تحلیل و بررسی در زمینه عوامل ایجاد آلودگی زیست محیطی در هنگام مصرف سوخت مازوت انجام می‌شود. همچنین روش‌های نوین کاهش این آلودگی‌ها و استفاده از فناوری‌های جدید بررسی و بهترین راه حل برای کاهش این آلاینده‌ها و حفظ محیط زیست در نیروگاه ایرانشهر مورد تحلیل و بررسی قرار می‌گیرد. با تعیین ده مالک اصلی، از بین روش‌های گوناگون، دو روش نانوامولسیون مازوت و روش گوگردزدایی از گازدودکش به روش جذبی تر انتخاب و پیشنهاد شده است. علاوه بر این با امکان سنجی استفاده از فناوری‌های جدید روش ایده‌الی برای کاهش آلودگی ناشی از احتراق سوخت مازوت در نیروگاه ایرانشهر انجام گردیده است. | ||

| چکیده [English] | ||
| Reducing air pollutions due to the combustion of Mazut fuel is one of the essential requirements of the power plants to prevent environmental damages. On the other hand, toxic contaminations in the air combine with atmospheric precipitation and cause acid rain, and thus their damaging effects increase and their effects are greenhouse gas and global warming. This study investigates the mechanical and metallurgical properties of sediments ash due to the combustion of Mazut fuel on torch and superheater pipes of Iranshahr power plant as well as its pollutants. Then, the factors that cause environmental pollution involve sulfur and nitrogen oxides using Mazut fuel are studied. Also, new methods of reducing these contaminations such as nanotechnology and the best solution for reducing these pollutants and preserving the environment in the Iranshahr power plant are analyzed. By determining the ten main criteria, two methods of Mazut nano-emulsion and wet flue gas desulphurization method have been selected and are suggested to reduce the contamination of the Mazut combustion in Iranshahr power plant. In addition, with the feasibility of using new technologies, an ideal method for reducing the pollution caused by the combustion of Mazut fuel at Iranshahr power plant has been carried out. | ||
