Whether an electro-hydraulic control valve for the mixed-gas pressure control in a combined cycle power plant (CCPP) of a steel mill meets the challenge of the gas turbine depends on its dynamic response. To obtain the dynamic characteristics of the electro-hydraulic control valve before it is manufactured, a dynamic design approach based on the physical simulation model is presented. The electro-hydraulic...
The pressure pulsation of the mixed gas is the major reason to result in the abnormal stop of the generating equipments in a combined cycle power plant (CCPP) of a steel mill. An active control method for the attenuation of the pressure pulsation in large-flow mixed-gas pipe was presented. The pulsation mechanism of the mixed-gas pressure was discussed. A series of active control valves and error...
