پایان نامه - بویلرها ، نحوه طراحی و انتخاب بویلرها
چکیده:
بشر از قرنها پیش به قدرت بخار پی برده بود ولی استفاده صنعتی از دیگهای بخار از سال 1712 میلادی توسط (ساوری و نیوکامن) با ساخت اولین دیگ بخار با پوشش سربی یا چوبی و با فشار کمی بالاتر از فشار اتمسفر آغاز گردید. در سال 1725 میلادی (هیستک بویلر) با صفحات فولاد پرچ شده و با فشار نسبی مورد استفاده قرار گرفت. با گذشت زمان مشخص گردید که تنها شکل عملی استفاده از دیگ بخاری مدور ساختن آنهاست که در سال 1795 با بوجود آمدن صفحات نوردی دیگ بخار بصورت مدور ساخته شد.
در این پایان نامه در فصل اول با بویلر و مفاهیم اولیه مربوط به بویلرها آشنا شدیم، سپس در فصل دوم انواع بویلر ها براساس پارامترهای مختلف تقسیم بندی و توضیح دادیم. همچنین طرز کاربرد و چگونگی طراحی همراه با نقشه های فنی بویلرها برای علاقمندان ارائه کردیم.
