Distiller Anti-Scale

Problem: The current anti-scale injector for shipboard flash-type distilling plant is very unreliable and cannot use the new concentrated solutions. If the injector fails, there is no way to detect it until the distiller fails and requires substantial maintenance.

Solution: MTTC, in conjunction with NSWCCD/NAVSSES Philadelphia, will design and test a new injector, derived from a commercial product. Land based and shipboard testing will confirm suitability.

Benefits

Estimated Navy Cost Avoidance:

Minimum annual:      $398 K

Minimum 15 Year:   $5,970 K

Fleet Impact: Fresh water is a vital commodity on ships and lack of it is a true morale issue. This project will substantially improve the reliability and maintainability of the numerous flash-type distilling plants in the fleet.

Status: Ongoing

Design and production of the prototype unit is complete. Testing is ongoing at NSWC/Philadelphia prior to shipboard installation. BUMED approval has been obtained. Installation onboard USS CARL VINSON (CVN-70) is expected in mid-FY 2002.

Applicability:

All ships with Flash-type Distilling Plants (including SSNs, CVNs, others)
