摘要： A system includes sensors configured to measure parameters related to a vessel including liquid level, gas flow rate, pressure in the vessel, temperature of the vessel, and feed-liquid flow rate. A signal processing unit receives sensor output signals and generates a first filtered output signal representative of liquid level, a second filtered output signal representative of gas flow rate, a third filtered output signal representative of feed-liquid flow rate, a fourth filtered output signal representative of vessel pressure, and a fifth filtered output signal representative of vessel temperature. A flow demand control unit receives the first filtered output signal and generates an output signal representative of feed-liquid flow demand. A shaping unit receives the second, fourth, and fifth filtered output signal and generates an output signal representative of shaped gas flow rate as a function of pressure, temperature, or combination thereof in the vessel. A liquid level control unit controls the liquid level within predetermined limits by controlling one or more components based on the output signals from the flow demand control unit, the shaping unit, and the third filtered output signal.

摘要： 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.
