دراسة آلية تآكل مسخنات هواء الاحتراق في مراجل توليد البخار في مصفاة بانياس

The search comprehensive analytical study to determine the problem erosion experienced by air heaters combustion in boilers to generate steam in Banias refinery, through a detailed study of the reality of the work of these heaters include: study (type of spent fuel in the burner, temperature exhaust gases actual, and analysis chemical products of these gases). It also includes research testing process to check corrosion in air heaters by preparing coupons metal of the same type metal heaters are grown for specific stream of exhaust gases near the heated first enters the air first, and prepare reports for it, with a chemical analysis of the sediment surface studied Coupon. The study concludes that the heated first exposed to significant erosion where low surface temperature below the dew point, therefore been proposed a new design for this heated by determining surface heat exchange between combustion air and exhaust gases so that the temperature stays above the dew point, which reduces erosion thisheated significantly.
