Corrosion sensors for condensate corrosivity in heat exchangers
- Case Western Reserve Univ., Cleveland, OH (United States)
Sensor technology, particularly that based on microelectronic fabrication methods, can measure properties of condensates in real time and can increase the quantity and quality of information gathered from accelerated testing in the laboratory. The objective of these studies is to develop a series of electrochemical corrosion sensors to measure the corrosivity of condensates formed within heat exchangers and vents of gas furnaces. Corrosion sensors have been developed to measure several corrosion parameters such as pH, time-of-wetness, and temperature. Measurements have been made on a series of simulated and real condensates ranging from aggressive to benign corrosivity. Subsequent testing of the sensors was performed at the American Gas Association Laboratories on 0as fired appliances. Data is presented from these tests and related to the corrosion behavior of the heat exchangers. Prototype systems were developed and tested for each type of sensor.
