Jonas, Inc. offers this simple, inexpensive device, which is installed outside the turbine, for the collection of exfoliated oxides and mineral deposits representative of deposition inside the turbine. The Collector works at pressures up to 3000 psi and temperatures up to 1000oF. The collected deposits are analyzed to predict deposition and corrosion inside the turbine, and to assess boiler carry-over and the effects of steam and water chemistry upsets. Turbine deposits can cause corrosion of blades, rotors and discs, reduction of turbine efficiency and MW generating capacity, and malfunction of valves and seals. Exfoliated oxides cause solid particle erosion. The optional Flow Totalizer allows the average concentration of impurities to be determined.
The filter-like device, which simulates the turbine conditions governing deposition from superheated steam, can be installed at any steam sampling point. The Deposit Collector/Simulator is accessible during operation and its filter elements can be periodically replaced. After exposure to steam, the weight and chemical nature of the accumulated deposits are determined. The recommended analyses include EDAX, optical and SEM microscopy, X-ray diffraction, and wet chemistry methods. Jonas, Inc. can perform these analyses upon request.
