Generating Bank DCS

National Boiler Service has set the benchmark for boiler

component evaluation. NBS developed the state-of-the-

art Generating Bank Data Collection System (GenBank

DCS) and employs the system to map the entire

Generating Bank.

Completely wireless, the GenBank DCS offers advanced

electronic data collection that reduces manual entry

time. This system produces accurate measurements of

the drums, tube thickness, and the completed rolled joint

percentage of wall reduction.

The NBS Difference - Developing New Industry Standards

NBS Gen Bank DCS Î Eliminates manual data entry and provides cost-effective

data collection capabilities.

Î Measures tube sheet holes by extracting information using 3-point bore mics and resolves data to a spreadsheet representing the drum hole layout.

Î Color codes data according to wall reduction percentage.

Î Identifies oversized or undersized tube sheet holes and under-rolled or over-rolled generating bank tubes.
