Alkanolamines and ethylene polyamines as cold-end additives |
| abstract |
The present invention is drawn to ethylene polyamines in combination with certain alkanolamines as cold-end additives. More specifically, it has been discovered that if these additives are fed to the moving combustion gases of a combustion system which uses sulfur containing fuel and upstream of cold-end surfaces to be treated, the additive will travel along with the gases as vapor and/or liquid droplets and deposit on the cold-end surfaces. As a result, the amount of sulfuric acid corrosion of metallic cold-end surfaces is reduced. |
