- The Steam Plant at Sandia National Laboratories/New Mexico (SNL/NM) supplies on average 680,000 kg/day (1.5 x 10⁶ lb/day) of saturated steam for space heating and laboratory processes for SNL/NM, Technical Area 1, the eastern portion of Kirtland Air Force Base, the Department of Energy`s Albuquerque Office, and the KAFB Coronado Club. The primary fuel is natural gas (740 mscf/yr); the secondary fuel in the event of a natural gas interruption is diesel fuel. Two storage tanks provide a diesel fuel reserve of 1.5 million gallons. The Steam Plant has been in continuous operation since 1949, and some of the boilers are past their design life. Each of the boilers is controlled through a central Digital Control System (DCS). The DCS design is based on the stoichiometric equation, where the O₂ stack concentration and load rate are set points and the combustion air and gas flow are adjusted based on the equation. The DCS was installed and programmed in 1992, but has not been updated since. Long range studies are being conducted to determine the fate of the steam plant, but implementation of any of these options is at least 5 years in the future. Because it is a major source of air emissions, water and chemical use, and waste water at SNL/NM, the steam plant pursued immediate solutions to reduce costs and pollutant releases, while still providing uninterrupted, quality service to its customers. This paper will summarize the ongoing efforts to conserve water, and reduce air and wastewater discharges at the SNL/NM Steam Plant. These improvements were identified through a Pollution Prevention Opportunity Assessment, an Emissions Reduction Study.
