Abstract
PURPOSE:To obviate the corrosion resulted from the lowering of temperature of exhaust in the case of a waste heat recovering type heat exchanger, by attaching a recoverer for recovering a highly acid drain and a neutralizer for neutralizing the drain. CONSTITUTION:A finned tube type heat exchanger 6 is positioned over a burner 4, and over the heat exchanger 6 is positioned the the finned tube type heat exchanger 1 for recovering waste heat. In the case of a heater including the above- mentioned arrangement, a higly acid drain is produced below the waste heat recovering heat exchanger 1. This drain is received into the recovering section 2B, then is introduced via a drain pipe 2A into the neutralizer 3 where it is neutralized. Furthermore, the surfaces of the heat exchanger 1 are treated to have an acid proof coating for example a tin or nickel plating, so that the corrosion problem is solved. As a neutralizing agent above mentioned solid neutralizing materials such as solid metal paraticles, a powder inorganic compound or cement are usable.
