Patent number: 7931041Abstract: A system includes sensors configured to measure vessel parameters. A signal processing unit receives sensor output signals and generates a first, second, third, fourth, and fifth filtered output signals representative of liquid level, gas flow rate, feed-liquid flow rate, vessel pressure, and vessel temperature, respectively.

Patent number: 6694742Abstract: Critical stress in a gas turbine can be estimated using one or more readily measurable temperatures in the gas turbine. First and second critical temperatures can be estimated based on the at least one measurable temperature using heat conduction and convection equations. Subsequently, the critical stress can be estimated in real time according to a stress model prediction based on the difference between the critical temperatures, and possibly the rotational speed of the turbine, and some parameter, such as air pressure, that is indicative of air flow around the turbine component. Operation of the gas turbine can thus be controlled using the estimated critical temperatures.Type: GrantFiled: June 26, 2002Date of Patent: February 24, 2004Assignee: General Electric CompanyInventors: Ravi Rajamani, David Allen Flodman, Robert Scott Garry, Bruce Gordon Norman, Leroy Tomlinson
