COLORADO RESEARCH PROJECT USES GEOTHERMAL WATER TO PREVENT BRIDGE ICING

A test section of bridge deck has been constructed in Glenwood Springs, Colorado, to determine the feasibility of a heat transfer system using hot spring to control preferential icing. The geothermal water is pumped to a 4-inch header pipe along the bridge deck where it heats liquid-ammonia which vaporizes and flows through 1-inch pipes underneath the bridge deck. All heated sections of the bridge deck have remained free of snow and ice during the three storms that have occurred since construction. Thus far, this system appears feasible for use in nearby Glenwood Canyon.
