PURPOSE:To heat the fluid to be heated up to high temperature by a method wherein a second heat exchanger is provided in the fluid to be heated inside a reservoir of heat medium solution enclosed in a sealed up container. CONSTITUTION:A flue group 2 for high temperature gas is inserted into a reservoir 1A of a sealed up container 1 enclosed with 55% solution of lithium bromide as a heat medium solution maintaining inside pressure not exceeding the atmospheric pressure while heat exchangers 3A, 3B flowing the fluid to be heated inside thereof are inserted into a steam chamber 3A connected to another steam chamber 1B in the sealed up container 1 constituting a heat exchanger 3. Another heat exchanger 5A is inserted into the space above the flue group 2 inside the reservoir 1A constituting the second heat exchanger 5 while the fluid to be heated different from the fluid flowing inside the heat exchangers 3A, 3B is flowing inside the heat exchanger 5A. The fluid flowing inside the heat exchanger 5A is preliminarily heated in the other heat exchanger 6A inserted into the second sealed up chamber 3A. |
