Inhibitors for Boiler-Water Corrosion

Abstract

Thermal power generation based on boiler/turbine system and using fossil fuel for the generation of steam prov-ides vast wold's supply of electricity. In India power generation is also based on the same system. Water tube boilers have evolved as the only practical means of producing steam in sufficient quantities and at the appropriate pressure for running the steam turbines to generate electricity. The corrosion problems being faced by the system are not in common with hydro electric plants or atomic power station. Basically, the thermal power plants consists of boiler, boiler drums, superheater, heater, steampipes, rotors, bladings. erosion shields. turbine casings, condensers. return systems, etc. Each item has its own problem and. therefore, requires proper attention to achieve better performance.
