This paper summarizes the results of a recent research project comparing laboratory performance of a
polyamine-based to a traditional oxygen scavenger-based boiler water treatment. The corrosion of low
carbon steel, copper and a copper alloy (admiralty) was measured for both programs under different
simulated boiler feedwater and condensate return conditions. In addition, we will present the field test
results of the application of a polyamine-based boiler water treatment in a 180 psig (13.43 bar, 1.343
MPa) watertube boiler.
Key words: Boiler treatment, polyamine, coupon weight loss, low carbon steel, yellow metals, corrosion,
corrosion inhibition, field trial.
