Material and heat flow analysis in thermal energy storage and transport system utilizing unused heat from bagasse boiler
Sugar production is the main industry in Tanegashima, Japan. Whilst the sugar mill recycles sugarcane bagasse as a fuel, it concurrently generates large amounts of unused 200 °C heat during operation. Raw sugar is shipped to a refinery in Osaka for the final stages of production, which uses a city g...

Sugar production is the main industry in Tanegashima, Japan.

However, factories in Tanegashima need a continuous supply of process steam at temperatures of up to 120 °C.

A process flow diagram of the sugar mill has been developed, and the amount of available heat, the potential storage capacity, and the transportable amount of heat have been calculated.
