Abstract : Currently most military district steam heating systems operate by maintaining a constant steam pressure regardless of actual steam demand. This method of operation, while practical, is often the source of significant energy losses. Energy conservation is a national goal and may perhaps be a future necessity. In accordance with this outlook, researchers at the U.S. Army Construction Engineering Research Laboratory (USACERL) examined the Steam Dispatching Control System (SDCS). SDCS is a control system for reducing the losses in a distribution system by controlling the steam pressure. Lowering the steam pressure to slightly above the amount needed to meet the thermal demand reduces the steam temperature with only slight reductions in steam enthalpy. Thermal losses at the lower temperature are reduced and leak losses are also diminished. The past success of SDCS in industry indicated that SDCS could be successfully applied to military district heating systems.
