1 can 2 circuit die instantaneous heating type heat exchangers

摘要

PURPOSE: To provide a one-boiler two-circuit type instantaneous heating heat exchanger in which some heat exchanging pipes are hardly damaged at a combustion boiler part and they have durability. ;CONSTITUTION: A one-boiler two-circuit type instantaneous heating heat exchanger is operated such that a hot water feeding circuit 20 and a bath additional boiling circuit 30 are introduced into a combustion boiler 10 so as to perform an instantaneous heating of water flowing within each of the circuits. The hot water feeding circuit 20 is constructed such that the heat exchanging pipes 21 are wound around the combustion boiler, thereafter they are passed within the combustion boiler 10. The bath additional boiling circuit 30 is constructed such that its heat exchanging pipes 2 are directly passed within the combustion boiler without being wound around the combustion boiler.;COPYRIGHT: (C)1993,JPO&Japio
