Craig Station’s chemistry specialist, Joni Zaragoza knows plenty about the benefits of oxygenated treatment systems in power plant boilers, so when Dave Kalinowski, Tri-State’s technical representative at Springerville Generating Station (Springerville, Ariz.), called on her to help them solve a boiler chemistry problem that was right up her alley she was ready, willing and able to provide the necessary expertise.

That expertise earned her and Tri-State one of the electric industry’s coveted 2013 Technology Transfer Awards from the Electric Power Research Institute (EPRI).  Zaragoza was recognized for her accomplishment at an EPRI awards ceremony held in San Francisco on Feb. 18.

EPRI is an international, non-profit, research and development organization that brings together scientists, engineers and experts from academia to address challenges in the electric utility industry. Zaragoza’s EPRI award was for “Drum Oxygenated Treatment.”

Zaragoza’s recommended oxygenated treatment systems were installed on units 3 and 4 at the pictured Springerville Generating Station.

“This was really a combined effort between Tri-State, which owns the 400-megawatt unit 3 at Springerville and Salt River Power (SRP), which owns the adjacent 400-megawatt sister unit 4 at the plant,” explained Zaragoza. The chemistry specialist went on to explain that both of these units were originally built with poorly designed sample panels. Sample panels are used for monitoring the water chemistry in the boilers.

“We worked out a joint project between Tri-State and SRP in which we installed new state-of-the-art sample panels for each of the Springerville units utilizing the guidelines recommended by EPRI, plus some additional features of our own to make sure that everything was covered,” she said.

“This new equipment allows us to more precisely monitor the water chemistry in the boiler and avoid corrosion, which can cause tube leaks that force a unit off line or harmful depositions that require costly chemical cleanings in the boiler,” said Zaragoza.

Arnie Lindberg, chemistry manager at Craig, who also recommended Zaragoza for the EPRI award, summed it up nicely in a recent EPRI newsletter when he said that, “Joni’s willingness to share her technical experience with SRP on the Springerville unit 4 conversion not only directly helped SRP, but also helped make the plant safer for everyone.”
