Abstract:

An investigation was conducted by the Naval Facilities Engineering Service Center NFESC to determine current and emerging technology for cost-effective, durable materials for condensate return lines associated with district piping systems for central steam distribution on Navy shore facilities. The distributed steam may be used for building heating, cooking, ships supply, and other direct-use processes. This investigation sought to identify materials and specific technology to improve the reliability and maintainability of these condensate return lines. The investigation included literature searches for technology associated with all types of piping materials including piping material and piping processes not generally associated with steam condensate return. The search for a durable material to replace existing materials used for condensate return piping was unsuccessful. Provided that returning condensate to the boiler is economical based on site factors, improvements to the reliability and maintainability of condensate return lines can be accomplished through stricter adherence to existing installation specifications and operating procedures. Alternatively, the reliability and maintainability of a steam system may be improved by converting all or part of the heating load over to a hydronic system. The economics of this conversion would likely pay only for those facilifies considering system replacement or system expansion. MM
