PURPOSE:To obtain a safe and well-managed heater utilizing energy derived from difference in density by producing a hot air through a heat exchanger from absorbed heat generated when a medium steam is introduced into a heated absorptive exothermic salt solution to absorb. CONSTITUTION:A solvent tank 10 is filled with a solvent 11 such as water while a solution chamber 20 filled with a concentrated solution 21 of an absorptive exothermic salt such as alkali metal. Then, the solvent 11 and the solution 21 are heated with a heater 40. The solvent 11 is evaporated and absorbed into the solution 21 elevated in the absorptivity by the heating and heat is generated by the solution 21. The heat is released into air delivered from a blower 51 through a heat exchanger 30 to produce a warm air. The solvent 11 liquefied with the heat exchanger 30 returns to the tank 10 passing through a gutter-shaped member 26 and a drain pipe 27. The solution 21 diluted by the absorption of the solvent 11 is exchanged between the concentrated solution withdrawn from a drain pipe 27 not illustrated. This provides a safe and well-managed heater. |
