| Outline of Final Research Achievements |
A compact industrial boiler system that is combined with solar-thermal collector pipe has lower fuel consumption and CO2 emissions than conventional systems, and has been subjected to basic testing. High-pressure steam generated by the compact boiler drives a steam ejector to decrease the pressure inside the tank, causing the generation of low-pressure steam within them using solar thermal energy. Steam from both sources is mixed in the ejector and is supplied on demand at low to medium pressure to where its use is required. Evaluation results of the operating performance of the boiler system using evacuated dual glass tube confirmed that the internal pressure of the tank was maintained at close to predicted levels, and that there was a stable supply of low-pressure steam.
