Advances in Icing Control at Corps Hydraulic Structures. Ice Engineering. Number 31, November 2001.

摘要

Adhesion of ice to surfaces creates problems for many industries, including hydropower and navigation. At present, ice removal techniques are costly, hazardous, and time-consuming. Anderson and Anderson (1992) reported that at one hydropower station in Sweden, ice-related costs averaged $0.2 million per year over a 10-year period. At Corps of Engineer project, annual maintenance costs resulting from ice problems were estimated to be $33 million in 1992 (Haynes et al. 1993). Recent advances in deicing and anti-icing technologies have been evaluated in the laboratory and the field to assess further applicability for use at hydraulic structures operated by the U.S. Army Corps of Engineers. At Corps projects, considerable resources are expended annually to keep ice off steel and concrete structures to maintain operations through the winter months. Comparisons of the performance of these new technologies with current practice are given herein.
