Enamel can significantly extend the life of heat exchanger systems in power plants. Unprotected steel surfaces would be highly corroded by the diluted sulphuric acid occurring in the process. The service life of the profiled steel heating surfaces used below the acid dew point is significantly increased. The specially profiled enamels for air and gas preheating in power plant technology extract heat from the flue gas and transfer it to the fresh air sucked in via fans. The technical enamelling consists of tightly packed, folded sheet steel pallets which can absorb or release flue gas heat. Wherever sulphuric acid condenses and a sulphuric acid concentration is generated (60 to 70%) due to the plant temperature and flue gas humidity enamelling is technically and economically superior to other materials.
