Long-distance transmission of hot water for district heating. [Profile of potential heat source/market distances]
The technical feasibility of hot-water-based district heating has been demonstrated by years of operation of large-scale systems in Europe and parts of Asia. District heating affords the opportunity of substituting low-grade heat resources for prime fossil fuels in the space- and water-heating market, thus conserving scarce fuels. Development of cheap, reliable long-distance hot-water-transmission technology could lead to far-reaching consequences for the U.S. The profile of distances between markets and potential heat sources is investigated. Potential sources include geothermal resources and power plants. Typical market characteristics are analyzed, and the technical and economic aspects of long-distance transmission to these markets is presented. Results show that the limits to feasibility of long-distance hot-water transmission are determined by economic, not technical factors. Inclusion of district-heat service for air conditioning, and heating and drying industrial processes can dramatically affect the economic picture for district heating, especially in warmer climates. Cost-reducing developments in transmission technology could have greater payoff when applied to distribution systems. 11 refs., 5 tables, 8 figs.
