corrosion in limestone plants

Corrosionpedia - What is a Limestone? - Definition from ...

A 1mm thick deposit of limestone on the surface of heating coils may result in an energy loss of 10%. Corrosion and limestone deposits in plumbing systems lead to broken pipes, blockages and eventual flooding. Increased energy and water consumption as well as all other related costs are results of diminished performance of heating installations.

Flue-gas desulfurization - Wikipedia

A new, emerging flue gas desulfurization technology has been described by the IAEA. It is a radiation technology where an intense beam of electrons is fired into the flue gas at the same time as ammonia is added to the gas. The Chendu power plant in China started up such a flue gas desulfurization unit on a 100 MW scale in 1998.
