CH-89-10-4 -- A Steam Dispatching Control System for Fort Benjamin Harrison, Indiana PDF

A steam dispatching contro/system (SDCS) is system for improving the therma/ efficiency of steam distribution networks. The SDCS regulates the steam pressures in the network just enough to satisfy the steam requirements of the connected buildings. This minimizes the distribution network thermal losses. The steam distribution network at Fort Benjamin Harrison, IN, has been selected for future SDCS field demonstration. Numerical analysis of the system, using a distribution network thermal efficiency computer model, indicated that the SDCS is a viable option for this site. About 12 TJ (11 by 10g) Btu of steam energy would be saved each year, which is about 3.4% of present annual steam energy. The coal savings associated with this translates to an estimated sirnple payback time of 4. 2 years. Had natural gas been used as the fuel, this value would be about 1.3 years.
