PURPOSE:To heat plural fluids to be heated respectively up to specified temperature without utilizing any specific temperature controller. CONSTITUTION:A combustion cylinder 3 and flue group 4 are inserted into a heating medium liquid reservoir 2 in a sealed up container 1 maintaining the inside pressure not exceeding the atmospheric pressure while the inside of the container 1 is divided by a partition board 9 into a chamber 8A containing a part of the flue group 4 and another chamber 8B containing the combustion cylinder 3 and the residual flue group 4 and then the chamber 8B is enclosed with water while the other chamber 8A is enclosed with aqueous solution of lithium bromide or calcium chloride with boiling point higher than that of water as heat medium. Besides, the heat exchangers 7, 11 flowing fluids to be heated (a), (b) are provided in a vapor chamber 6 and the outlet of the heat exchanger 11 is connected to another heat exchanger 10A immersed in the heating medium liquid inside the chamber 8A. The liquid level L1 in the chamber 8A is made lower than the liquid level L2 in the chamber 8B at specific concentration while the water volume equivalent to the evaporated water from the chamber 8A is flowed over the partition board 9 from the chamber 8B. |
