主蒸汽温度700℃超超临界锅炉水冷壁选材分析
, PP. 66-71
Keywords: 超超临界,600mw机组,锅炉,主蒸汽温度,水冷壁,选材
Abstract:
针对超超临界600mw机组主蒸汽温度为700℃的锅炉(700℃锅炉)水冷壁选材问题,分析比较了t12,12cr1movg,t23,t24,t91,t92,t122(hcm12a),vm12shc和617mod等备选管材的适用性,包括母材和焊接接头的持久强度、热疲劳和蠕变疲劳,母材和焊接接头的抗蒸汽腐蚀和抗烟气腐蚀性能,热成型性能及可焊性。同时,提出超超临界700℃锅炉水冷壁应选用t92高强度马氏体钢管和617mod镍基合金管,应采用电加热板对t92水冷壁管对接焊接接头进行焊后热处理。
