To provide a rotary regenerative heat-exchanger provided with members, such as heat-transfer element, in which heat resistance is enhanced, and simplification in production processes and effect on environment can be improved, without degradation of excellent corrosion-resistance of conventional enamel.
This heat exchanger is constituted of a rotation center-shaft 1, a rotor 2, a partition 3, a basket, a heat-transfer element in the basket, and a seal in the radial direction, extending axially along the edge of the partition 3. In the heat exchanger, any one of the heat-transfer elements, the basket, the partition 3, and the axially extending seal is covered with an enamel comprising 50-60 wt.% of SiO2+ZrO2+TiO2, 10-20 wt.% of Al2O3+B2O3, 10-15 wt.% of Na2O+K2O+Li2O, 10-15 wt.% of CaO+BaO+SrO, and 1.5-5.0 wt.% of FeO+ CoO+NiO+CuO.
