Abstract
The efficiency and power output of a steam turbine can be dramatically reduced when deposits form on the turbine blades. Disassembly and mechanical cleaning of the turbine is very time consuming and costly. Deposits can be removed from the turbine internals in situ by foaming an appropriate cleaning solution and injecting it through the turbine, dissolving the deposits and removing them from the system. Because disassembly of the turbine is not required, foam cleaning is a much faster and more cost-effective method of removing deposits. In recent years, HydroChem has removed copper deposits from over 130 Westinghouse and General Electric turbines nationwide using patented equipment.
