Abstract:
PURPOSE:To enhance heat-accumulating density and supply thermal energy having favorable property free from lowering of temperature, by capsules containing pentaerythritol and an organic heat-transmitting medium immiscible therewith are contained in a high-pressure water tank of a steam accumulator. CONSTITUTION:In the interior of each of the capsules 6, a crystal (particulates) of a latent heat type heat-accumulating material consisting of pentaerythritol is contained in the condition of being immersed in an organic heat-transmitting medium immiscible therewith, e.g., a silicone oil. When accumulating heat, a steam is blown into pressurized water 5 contained in a pressure vessel 3 through nozzles 4, thereby raising the temperature of pressurized water 5. When the temperature of water 5 exceeds 188 deg.C, pentaerythritol undergoes a crystalline transition, so that the quantity of heat accumulated at 188 deg.C is increased. When releasing heat, a controlling valve 2 is opened, whereby pressurized water 5 is evaporated, and steam flows out. When the temperature of water 5 is lowered below 188 deg.C, pentaerythritol is converted into a low-temperature stable phase, and steam of a constant temperature approximate to 188 deg.C is discharged.
