Abstract:

A concept to reject heat generated by an underground power plant by disposal of exhaust steam to rock tunnels was evaluated by means of a field test. The tunnel walls would, thus, be used to condense the steam and store the heat under a transient heating load. Heat transfer to the rock was initially predicted using the well-known Carslaw and Jaeger analytical model which considers the test tunnel to be represented by a hollow cylinder in an infinite medium initially at a constant temperature. Information was developed regarding the heat transfer coefficient associated with the condensation of steam on rock. Establishing a comparison between the measured and predicted temperatures was complicated by the problem of rock fall which retarded the rate of temperature rise. The writers feel that meaningful comparisons are valid for the first few days of the test, prior to any substantial rock fall.
