High temperature erosion testing in a gasifier environment
The development of materials with the ability to operate in adverse conditions while resisting the effects of erosion and corrosion is essential to the future success of high efficiency power plants. Many next generation coal power plants are envisioned as combined cycle, with gasifiers used to produce both steam and syngas. The gasifier sections of these plants require materials of construction that are resistant to the effects of erosion from silica found in the gas streams and corrosion caused by a reducing atmosphere that may contain sulfur and chloride compounds. The Albany Research Center has developed a test apparatus designed to test the erosion-resistance of candidate materials under a range of environmental conditions, including those found in gasifiers. This Hostile Atmosphere Erosion Wear test apparatus (HAET) has been used to evaluate a group of high alloy candidate materials such as iron aluminide and Haynes HR 160, and compare them to a conventional 310 stainless steel. Erosion tests were conducted using 270μm silica abrasive, a typical impact velocities of 20 m/sec at temperatures up to 700°C in an atmosphere simulating gasifier conditions. The effects of erosion under these conditions on the surface scales that form are described. The total loss rate, loss rates due to erosion and corrosion for the test materials are compared.
