The erosion of ashlock hopper valves in coal gasification systems and the maintenance downtime resulting from this erosion are a cause of considerable concern for the coal conversion industry.
In order to alleviate this problem a test rig was designed and built to simulate service conditions of temperature, pressure differential and valve by: 3. Rig test results confirm the potential for reduced erosion, but illustrate the profound effects of microstructure on the erosion behavior of a given ceramic.
This has significant implications for both the manufacture of components and for techniques used to apply ceramics in, for instance, critical areas of valve and pump by: 2. Erosion-resistant materials for critical areas of coal liquefaction and coal gasification systems. This book discusses the properties of coal mineral matter abrasion and particle impaction erosion wear in those power plants using coal.
Its main thrust is to provide remedial measures for these problems, Since coal is such a soft, flow-strength material, its wear-causing characteristics depend largely on the presence of abrasive mineral species.

Until the mid 's the process was operated at several sites in Germany to derive liquid hydrocarbons from coal as a substitute to standard crude oils. Materials considered for application in the high temperature gaseous environments that are present in various coal-gasification processes must be resistant to corrosive and erosive wear.

Publisher Summary. Coal is used primarily as a fuel, so its most important property is its heat of combustion. Gross calorific value, also known as higher heating value (HHV), is determined by measuring the heat released when coal is burned in a constant-volume calorimeter, with an intitial oxygen pressure of 2 to 4 MPA, and when the combustion products are cooled to a final temperature.

It is intended as a guide. For the current research, hardfacings of tungsten, titanium nitride and other materials were applied to ferrous alloys by CVD to provide valve components for coal gasification applications that are resistant to erosion, abrasion and corrosion.
EXPERIMENTAL Cited by: 1. Cobalt-base alloys have enjoyed extensive use in wear-related engineering applications for well over 50 years because of their inherent high-strength, corrosion resistance, and ability to retain hardness at elevated temperatures.
