Abstract:
The invention relates to a method for the automated discharge of condensate from a pressurized gas system by means of a condensate drainage means, wherein the condensate drainage means has a collecting region for the condensate, a sensor for detecting condensate in the collecting region, and an actuable drainage valve for the discharge of the condensate from the collecting region, wherein the method has, in chronological, repeating sequence: a collecting step (S1, S2, S3, S4) in which condensate is collected over a predefined collecting duration; a detection step (D1, D2, D3, D4) which at least terminates the collecting step (S1, S2, S3, S4) and which serves for the detection of condensate in the collecting region by means of the sensor; a discharge step (A1, A2, A4) in which, over a predefined discharge duration, condensate is discharged if condensate is detected in the collecting region in the detection step; characterized in that, in the event of condensate being detected for the first time or at the latest repeatedly in the detection step (D1, D2, D3, D4), the collecting duration of at least one of the subsequent collecting steps, preferably of the next collecting step, is shortened and/or the discharge duration of at least one of the following discharge steps, preferably of the next discharge step, is lengthened in terms of time and/or a degree of opening of the drainage valve in at least one of the following discharge steps, preferably of the next discharge step, is increased, and in that, in the event of no condensate being detected in the collecting region for the first time or repeatedly, the collecting duration of at least one of the following collecting steps, preferably of the next collecting step, is lengthened and/or the discharge duration of at least one of the following discharge steps, preferably of the next discharge step, is shortened in terms of time and/or a degree of opening of the drainage valve in at least one of the following discharge steps, preferably of the next discharge step, is decreased.
Abstract:
The invention relates to a method for fault monitoring of a discharge valve (16) of a condensate drainage means (1) of a pressurized gas system, wherein the condensate drainage means (1) has a discharge valve (16), which discharge valve has a valve element (19) which can be actuated by a control circuit (15) and which can be moved between a closed position and an open position and which serves, in the open position thereof, to discharge pressurized condensate from the pressurized gas system via a discharge region (18), arranged downstream of the valve element (19), of the condensate drainage means and, in the closed position thereof, to maintain the pressure in the pressurized gas system, wherein the method has: a closing step, in which the control circuit (15) triggers a closing movement of the valve element (19) in the direction of the closed position, and/or an opening step, in which the control circuit (15) triggers an opening movement of the valve element (19) in the direction of the open position; and a respectively subsequent step for monitoring the closed position or open position of the valve element (19). The method according to the invention is characterized in that, in the step for monitoring the closed position, a non-closed position is detected on the basis of a discharge flow of the pressurized gas, of the condensate or of mixtures thereof in the discharge region (18) or at the valve element (19), or in the step for monitoring the open position, a discharge flow of the pressurized gas, of the condensate or of mixtures thereof in the discharge region (18) or at the valve element (19) is detected.

Abstract:
A condensate recovery system comprises a plurality of drain lines for draining condensate from an associated steam plant. Each drain line incorporates a steam trap and feeds into a common condensate return line running between the drain lines and a condensate receiver tank. The system further comprises an acoustic sensor positioned along the common condensate return line, upstream of the receiver tank, for providing an acoustic output indicative of the collective steam loss through steam traps upstream of the sensor.
Abstract:
A method of monitoring the status of a plurality of steam traps includes sensing with a monitor at least one process condition in each of a plurality of steam traps, transmitting radio frequency signals responsive to the sensed process condition of each steam trap with transmitters associated with the steam traps, and receiving the signals generated by the transmitters with a receiver. In one embodiment of the invention, the signals from at least some steam traps are received and retransmitted by a repeater positioned between the steam traps and the receiver.
