Abstract
A method and apparatus are disclosed for determining steam quality wherein heat is added to or removed from a sample flow of steam to reach a point of superheating or subcooling. The amount of energy required to superheat or subcool the sample is factored in with other parameters such as steam flow rate, temperature and pressure to determine the quality of the steam. The steam quality sensor has many applications in equipment such as turbines, heat exchangers, condensers and the like.
Claims18
An apparatus for measuring steam quality comprising:
- (a) means for establishing a flow of sample steam through a chamber;
- (b) means for adding heat to or removing heat from said sample steam within said chamber;
- (c) means for detecting superheating or subcooling of said sample steam within said chamber;
- (d) means for determining the amount of heat added to or removed from said sample steam within said chamber to produce said superheating or subcooling;
- (e) means for determining the rate of steam flow through said chamber;
- and
- (f) means for determining the quality of said sample steam based on the amount of heat required to produce said superheating or subcooling of said sample steam and said rate of flow of said sample steam through said chamber.
