Thermodynamic Analysis of Feed Water Heating Repowering of Mohammad Montazeri Steam Power Plant

در اين مقاله، بازتواني نيروگاه شهيد منتظري اصفهان به روش گرمايش آب تغذيه مورد بررسي قرار گرفته است. براي اين كار، سه طرح جداگانه پيشنهاد شده است كه به ترتيب مبدل‌هاي فشار ضعيف، مبدل­هاي فشار قوي و هر دو گروه مبدل­ها با مبدل جديد جايگزين مي‌شوند. از بازده ­هاي انرژي و اگزرژي، به عنوان توابع هدف استفاده شده است. براي انجام شبيه‌سازي از نرم‌افزار Cycle-Tempo استفاده شده است. با توجه به نتايج بدست آمده، در طرح جايگزيني كليه گرمكن­هاي آب تغذيه با دو مبدل بازياب، بيشترين بازده اگزرژي حاصل مي­شود. در اين حالت، توربين گاز مدل Westinghause-401 بهترين گزينه است كه بازده­ هاي خالص انرژي و اگزرژي و توان توليدي سيكل به ترتيب، 8/12، 1/13 و42 درصد افزايش مي­يابند.

This study investigates the feed water heating repowering of Isfahan Montazeri Steam Power Plant is. To do this, three designs have been suggested; low pressure heat exchangers, high pressure heat exchangers and both of heat exchangers respectively are replaced by the new heat recovery heat exchangers. Energy and exergy efficiencies are used as goal functions. Cycle-tempo software is used to simulate. As it shown in results, in the method of replacing all heat exchangers with two heat recovery heat exchangers, the maximum exergy efficienciy is reached. In this case, The gas turbine westinghause-401 is the best choice that energy and egergy grass efficiencies and power production of the cycle increase 12.8, 13.1 and 42 percents, respectively.
