STEAM SYSTEM DESCRIPTION

The NSAA steam system includes all mechanically and electrically interlocked ancillary parts, equipment and components required for safe and continuous operation of steam and high temperature hot water generation and delivery and condensate return including but not limited to: generators, pumps, valves, piping, insulation, traps, expansion joints, portable boilers, tanks, controls systems, terminals, software, instrumentation, ventilation, water softeners, compressors, regulators, etc.
The U.S. Naval Academy Central Heat Plant (CHP) is a High Temperature Hot Water (HTHW) system rated at 266 million BTU by way of (2) 100 million BTU high temp hot water generators (water tube boilers) and (1) 66 million BTU hot water generator (boiler). Each boiler is rated at 620,000 pounds of water per hour flow rate. All three boiler models are Indeck International La Mont series TJW-C. The controls platforms are Rockwell Automation, AllenBradley system. All three boilers are dual fuel. The primary fuel is natural gas, and the secondary fuel is No. 2 fuel oil (diesel). Historically, diesel is only consumed during periods of natural gas curtailments. Set point temperatures are 360° Fahrenheit winter mode, and 325° Fahrenheit summer mode. System design pressure is between 390-410 PSI and is set at the expansion tank.
Bancroft Hall Wing 1 and Wing 2
Steam generators and associated feed tanks are also found within Bancroft Hall Wing 1 and Wing 2, with a condensate tank in the C.S. tunnel. These generators serve several mission-essential functions and should be considered part of the HTHW system because the primary source of heat is the HTHW. The steam generators can also be considered segmented because they are independent of the HTHW system, but they are just as vital to the
