Abstract
低NOx石炭燃焼ボイラーにおけるボイラーチューブ用の溶接オーバーレイとして使用する合金は、重量%で、Cr:36〜43%、Fe:0.2〜5.0%、Nb:0〜2.0%、Mo:0〜1%、Ti:0.3〜1%、Al:0.5〜2%、C:0.005〜0.05%、(Mg+Ca):0.005〜0.020%、Mn:0〜1%、Si:0〜0.5%、S:0.01%未満、残部実質的にニッケル及び痕跡量の添加剤及び不純物を含んでなる。この合金は、低酸素分圧で傑出した石炭灰耐性を与える。この合金は、使用温度で硬度及び熱伝導率も経時的に増加させる。硬度の増加により、チューブの浸食耐性が改良され、熱伝導率の増加により、ボイラーの熱的効率及びその発電能力が増加する。
