    Abstract

    In Tanegashima, the sugar mill, which is the main industry recycles sugarcane bagasse as a fuel but concurrently generates the massive amounts of unused heat at 200 °C. Raw sugar is shipped to a sugar-refinery in Osaka where the sugar products are produced. The sugar-refinery uses a city gas boiler to generate a massive quantity of heat at 150 °C for refining. In order to resolve this spatial and temporal mismatch, we propose the application of chemical heat storage. Steam adsorption and desorption cycle of zeolite was employed in this work. Process flow diagram of the sugar mill was developed and potential heat storage capacity, the transport capacity for zeolite and reduction rates of city gas consumption at Osaka were calculated. From the results, it was revealed that the transport capacity for zeolite was restricting factor in the heat storage and transport system. In fact, heat storage capacity depends on desorption amount and regeneration rates, so potential heat storage capacity, the transport capacity for zeolite and fuel reduction rates at Osaka were recalculated using the results of the adsorption/regeneration tests.
