PROBLEM TO BE SOLVED: To store waste heat making it retainable for a long period, and to take out and use the heat of the temperature higher than that of the charged heat when using the stored heat in a continuous furnace that can continuously execute a plurality of treatments of a workpiece to be treated during the conveyance thereof.SOLUTION: In a heat utilization method of a heating apparatus 10 including a chemical heat pump 40 having a reaction vessel 41 storing chemical heat storage media 45 and a water tank 42, and a continuous furnace 11 having an exhaust line 25, exhaust gas from the continuous furnace 11 is supplied to reaction products in the reaction vessel 41 of the chemical heat pump 40, the heat is stored to progress the dehydration and endothermic reaction, and the chemical heat storage media 45 and steam are generated thereby. The steam shifted to the water tank 42 through a connection conduit 47 is condensed by a condensation unit 43, and the supply of the exhaust gas is stopped. Water in the water tank 42 is evaporated by an evaporation unit 44 to form steam. The chemical heat storage media 45 is brought into contact with steam shifted from the water tank 42, the hydration exothermic reaction is progressed to radiate the heat. |
