<p>The rotor (14) of an existing rotary regenerative air preheater is retrofitted with deeper cold end baskets (68) for general performance enhancement and/or for the tolerance of ammonium bisulfate deposits. The normal cold end support gratings (54) are removed and the support of the cold end baskets (68) of increased depth is at least partially from the existing rotor stay plates (26).</p> |
