ABSORPTION OF FLUCTUATION IN HEAT LOAD IN BATCH TYPE OPERATION

摘要

PURPOSE:To reduce heat loss extremely, by carrying out load leveling using both endothermic heat during hydrogen release of alloy for occluding hydrogen and exothermic heat during hydrogen occlusion of the alloy. CONSTITUTION:Hydrogen is released from the alloy A for occluding hydrogen in the regeneative tank 6 using excess heat when the heat is in excess state in a batch operation. A regenerative device which is used in the operation is obtained by providing the regenerative thak 6 packed with the alloy A for occluding hydrogen with the tank 7 for storing hydrogen packed with the alloy B for occluding hydrogen through the hyrogen pipe 8. The operation system is cooled by the endothermic heat during the operation, the evolved hydrogen is sent through the hydrogen pipe 8 to the tank 7, for storing hydrogen, and hydrogen is occluded in the alloy B for occluding hydrogen. While, when a heating medium in the heating medium pipe L is in a heat demanding state, hydrogen occluded in the alloy B for occluding hydrogen is released, transferred through the hydrogen pipe 8 to the regenerative tank 6, and hydrogen is occluded in the alloy A for occluding hydrogen in the regenerative tank 6. The heating medium in the pipe L is heated by the heat generated during this operation.
