摘要： A process for regulating gas pressures of a regenerator with a gas expansion turbine in a flue gas line with a generator, wherein a process regulator opens the inlet valves of a gas expansion turbine and/or the bypass valves or throttles the bypass valves, doing so once with operation and once without operation of the gas expansion turbine. The process regulator is followed by a plurality of function generators, which preset the correcting variables for the downstream valves and in which a first function course of the function generators for operation of the gas expansion turbine and a second function course of the function generators for operation without gas expansion turbine are stored. A quick-acting valve of the inlet valves is acted upon by the speed regulator and it is active only at the time of the start-up of the gas expansion turbine until synchronization of the generator.

摘要： A process and a device for avoiding regulator instabilities in surge limit regulators for protecting a turbocompressor from surging if a high proportional gain is selected for the surge limit regulator by a blow-off via a blow-off valve. The control of the velocity of closing of the blow-off valve over time is performed by a gradient limiter of asymmetric design, wherein no velocity limitation acts in the opening direction, but a freely parameterizable velocity limitation of the closing process of the blow-off valve is provided in the closing direction. The gradient limiter is inserted between the surge limit regulator, which receives the control signals on the actual value of flow and the desired value of flow from a subtracter, and the control line for a pneumatic or hydraulic operating device of the blow-off valve.

摘要： A regulating method for preventing surges in turbo-compressors, in which the compressor flow and forwarding pressure are continuously measured. The compressor operating point is defined by the compressor flow and the forwarding pressure. Surges are prevented by regulating the opening of at least one blow-off valve by a regulator with an adjustment parameter when the operating point has arrived at a blow-off curve that parallels a surge limit, but before the operating point arrives at the surge limit. The adjustment parameter is returned to an actual state of the blow-off valve by a readjustment circuit when a difference exceeding a predetermined threshold occurs betwen the actual state of the blow-off valve and the adjustment parameter of the regulator.

摘要： A method for reliably operating turbocompressors in which flow and forwarding pressure defining the operating point of a compressor are continuously measured. At least one blow-off valve or blow-around valve is opened by a blow-off regulating system to prevent surging once the operating point of the compressor has attained a blow-off curve that parallels a surge limit, but before the operating point can attain the surge limit so that the flow will attain a minimum level depending on the forwarding pressure. The speed at which the operating point moves relative to the blow-off curve or surge limit is determined continuously to obtain the opening of either one of the valves ahead of time. The blow-off valve or blow-around valve is opened at maximum speed by a procedure that supercedes a normal blow-off regulation system when the operating point has arrived at or beyond a rapid valve-opening curve representing a speed-dependent minimum distance of the operating point from the blow-off curve. The motion in opening the valve is discontinued and regulation of the valve is resumed beginning with its latest state by the normal blow-off regulation system when the operating point has traveled back beyond the rapid valve-opening curve.

摘要： A process for the reliable operation of turbocompressors with a surge limit control and a surge limit control valve is described, in which the compressor delivers gases with different compositions and the composition of the gas (molecular weight) affects the performance characteristic of the turbocompressor and hence the position of the surge limit in the performance characteristic. The different compositions of the gases are compensated here with the effect on the position of the surge limit and consequently on the position of the surge limit control line by using predetermined design values for the gas constant R, the isentropic exponent k and the compressibility number z within the surge limit control for the determination of the delivery head Δh and the volume flow V and plotting them in the form of a predetermined surge limit line (FIG. 2, FIG. 4), wherein the set point and the actual value are determined for the surge limit control from the graph, and the compressor is operated with the set points and actual values determined for the surge limit control with a minimally necessary distance from the surge limit.

摘要： To prevent surge of a turbocompressor (K), a anti-surge valve (27) provided at the compressor outlet is controlled by a controller (R). The input signal for the controller (R) is generated as a function of the instantaneous flow and the end pressure of the compressor (K) such that the controller responds more slowly to working point shifts in the direction of the surge limit line and more rapidly to working point shifts in the opposite direction. This is achieved by arranging an asymmetric time element or a gradient sensor in the circuit generating the input signal for the controller (R).

摘要： A process for operating multistage turbocompressors (2, 22, 42) with a plurality of controllers (15, 35, 55) which interact one with each other, in which each compressor stage has anti-surge control valves (5, 25, 45) of its own, which recycle into the suction lines (1, 21, 41) of their respective own compressor stage (2, 22, 42). The control is performed by flow computers (6,26,46) for calculating the suction flow and computers (7,27,47) for determining the minimum acceptable flow from the delivery head. A comparison unit (12, 32, 52) determines the difference between the set point (derived from delivery head) minus the actual value (flow) and whenever the actual value is too low compared with the set point, it brings about a gradual opening of the corresponding surge line control valves (5, 25 and 45) until the actual flow exactly corresponds to the flow set point, which depends on the particular delivery head. The control takes place via a maximum selection (14, 34, 54), which is arranged upstream of the anti-surge controller (15, 35, 55) with the signal lines (16, 36, 56) to the surge line control valve (5, 25, 45).
