| Abstract | Scaling problem at geothermal power station exerts an evil influence upon the power generation and the flow of terrestrial hot water and vapor in the station. This work examined the clarification of scale formation mechanism and the prevention for scale formation by the surface coating of rotor with organic compound. From observation results of rotor surface after working during one year, it is found that the coated surface only had a small amount of scale and that there are the traces of separation of scale, that is, the scale is easy to separate from this surface. Therefore, this surface coating has the role of the prevention of scale formation and the prolongation of workable surface conditions. |
