英文要約Title: "Research and development of geothermal power generation technique/ Development of small binary power generation system to utilize the geothermal resource in the low temperature range/ Development of the hybrid-type small generation system preparing corrosion and scale adhesion countermeasures to utilize both the steam and the hot water getting out of a hot spring" annual yearly report of 2014 from 2013 to 2016.

Name of outsourcing company: ADVANCE-RIKO, Inc. and Mabuchi Engineering, Co. Ltd.

1. Content and results, etc. of research collaboration
In this year, we started to be proactive in doing the power generation by the small portable power generation system to utilize the hot water getting out of a hot spring and the development of the heat exchange preparing corrosion and scale adhesion countermeasure.
We were conducting the verification test at the hot spring at Obama by the manufactured second steam power generation, confirming the performance of power generated by flowing steam into this generation system.
Everything was going according to the operation plan document. We write down the all items doing in this year as follows.

(1) Development of the heat exchange preparing corrosion and scale adhesion countermeasure used in the small portable power generation system.
Mabuchi Engineering, Co. Ltd. conducted verification experiments for corrosion and scale adhesion at the both hot springs of Naruko and Obama.
(1)-1: Investigation of corrosion condition, and scale adhesion experiment in the field.
(1)-2: Analysis of corrosion condition and scale adhesion.
(1)-3: Consideration of corrosion and scale adhesion countermeasure, and determination of design requirement for heat exchange.
(1)-4: Designing and test production of heat exchange.
(1)-5: Investigation of heat exchange equal to performance evaluation of maintenance.
(1)-6: Considering the highly corrosive-resistant frame of the small portable power generation system.
(1)-7: Net estimation of installation and maintenance cost.

(2) Second stage prototype of the steam power generation system making of the scroll type of the steam expander.
ADVANCE-RIKO, Inc. performed designing and assembly of the steam power generation, and did the verification test by this system worked by flowing the steam.
(2)-1: Designing consideration of second stage prototype of the steam power generation system making of the scroll type of steam expander.
(2)-2: Designing and assembly of second stage prototype of the steam power generation system making of the scroll type of steam expander.
(2)-3: Designing and assembly of second stage prototype of steam-water separator.
(2)-5: Demonstration of second stage prototype of the steam power generation system making of the scroll type of steam expander works at the hot spring of Obama.
