In small-sized steam plants, as a effective countermeasure for energy saving and reduction CO₂ emissions, a screw type compact steam generator unit “STEAM STAR” has been developed by KOBE STEEL, LTD. in 2006.
At present time, this machine has been improved power output, which is 132 & 160 kW.
This machine has many excellent features as bellow ;
1) The generating efficiently is about 50% better than a conventional turbine type. (It can be generated efficiently with stepless adapted for fluctuating steam flow rate)
2) It has excellent pressure control characteristic comparing pressure reducing vale.
3) The first time of all-in-one construction package in the industry.
In this paper, details of above-mentioned features are introduced and shows their application for steam systems, domestic credit system for CO₂ emission.
