Frazil Ice Problems and Solutions at Hydro-Power Intakes

by Eugene J. Gemperline, Harza Engineering Co, Chicago, United States,



Document Type: Proceeding Paper

Part of: Waterpower '91: A New View of Hydro Resources

Abstract:

Active and passive frazil ice effects on hydroelectric plant intake design and operation are described and references are provided. The most frequently encountered problems and the basic principles involved in good design are described. Active frazil ice problems addressed include the accumulation of ice on hydraulic and mechanical surfaces in the powerhouse and loss of conveyance capacity in the approach channel. Passive frazil ice problems addressed include accumulation in forebays, clogging of hydraulic structures and associated loss of conveyance capacity and head. Examples of problems and mitigation measures described in historical and current literature are provided and referenced.
