Thermoelectric Generators (TEGS) Application in Cathodic Protection
Recently we announced that Linc Energy Systems now represents Gentherm GPT Thermoelectric generators; here is an application for these remote power sources.
Cathodic Protection (CP)
The natural gas industry uses cathodic protection to control corrosion of pipelines, wellhead casings and tanks, steel pier piles, and offshore oil platforms. Thermoelectric generators (TEGs) provide cost-effective, reliable, and continuous electrical current to difficult to reach CP sites.
A metal pipeline is usually anodic, and by supplying an electric current, the pipe becomes passive or cathodic. As long as the electrical flow is arriving at the cathode (pipeline) faster than oxygen, then corrosion is prevented or significantly slowed.
Thermoelectric Generators (TEGS)
Thermoelectric generators produce electrical power by the direct conversion of heat from the combustion of fuel into electricity, offering a dependable supply of continuous current. The generators are usually located near the ground bed and fueled by gas from tanks, wellheads or pipelines. The output current can be adjusted using an integral variable resistor allowing the output current to match the ground bed resistance.
While a CP Interface design will vary depending on the TEG Model, the following are general offerings:
