Abstract
The minor scale steam plant is widely prevalent in the industrial world. However, change of steam flow, a small amount of steam, and low-pressure steam prevent energy saving technology in spreading minor scale steam plants. From such a reason, screw type small steam generator was developed, it was called micro steam energy generator. This machine enables effective use of steam in a minor scale steam plant and promotes the further energy saving and CO2 reduction. The advantage of this machine can control the downstream pressure, equivalent to a reducing valve, and generate the power in the wide range of steam flow. Furthermore, 60% or more of high efficiency was realized in the 100kW class steam turbine. The test result of this machine is shown in this paper.
