摘要： A steam generator has a water container and an upper heating device and a lower heating device, a first temperature detection device covering a temperature detection area including the area covered by the two heating devices, a control device for monitoring and evaluating the first temperature detection device and for controlling the activation state of the two heating devices. A flat first temperature detection device covers the outside of the container, and a second spot-like temperature sensor is located on the water container in a region of an upper border of the upper heating device. Both temperature detection devices are used to activate and deactivate the two heating devices such that at first the lower heating device is activated to start generating steam as fast as possible.

摘要： The present disclosure relates to a feedforward structure for controlling water level, in particular to a feedforward structure for controlling a steam drum water level in a steam turbine FCB test and a control method therefor. The feedforward structure includes a steam drum provided with a steam drum water level measurement sensor therein, a feed water pipe provided with a feed water flow measurement sensor therein, and a steam inlet pipe provided with a steam flow measurement sensor therein. A steam drum water level measurement value I in the steam drum water level measurement sensor is compared with a set value of the steam drum water level.

摘要： A steam generator and a method for generating steam, the generator comprising a steam chamber fed with water from a water from a water reservoir for heating by a heating source to generate steam, steam being delivered out through a steam outlet, and waste water being evacuated through a drain, the steam generator comprising a control chamber, in fluid communication with the steam chamber so as that a water level in the control chamber is indicative of a water level in said steam chamber; at least one water level-sensor configured for detecting the water level in the control chamber; and a control unit receiving a signal from the water level-sensor. There is further provided a method of generating steam in a steam chamber receiving Water is fed from the water reservoir simultaneously to the steam chamber and to the control chamber, through a single feeding valve, the feed water being mixed with hot waste water drained from the steam chamber, upstream of a drain pump.

摘要： Provided is a system, in which a display is mounted to a steam generating device to monitor a driving situation or an erroneous operation situation of the steam generating device through the display. It is possible to monitor an operation situation of a steam generating device through a simple screen configuration in real time at a glance, and enable a user to diversely analyze reasons by various factors when an abnormal operation is generated and cope with the abnormal operation.

摘要： A system includes the HRSG having an economizer disposed along a fluid flow path, and a drum disposed along the fluid flow path downstream of the economizer. The HRSG also includes a drum level control module configured to modulate an amount of the fluid provided to the drum along the fluid flow path and a supplemental control module configured to control an amount of the fluid in a different manner than the drum level control module. The heat recovery steam generator also includes a drum level event controller configured to monitor a rate of change of a level of the fluid in the drum. If the rate of change is over a threshold value, a signal goes to the supplemental control. If the rate of change is less than or equal to the threshold value, the signal goes to the drum level control module.

摘要： A method for determining a liquid level in a boiler of an apparatus having a temperature sensor for sensing a temperature which is indicative of a temperature of the liquid inside the boiler, includes inducing a temporary deflection of the temperature sensed by the temperature sensor; determining an evaluation temperature sensed by the temperature sensor after inducing the deflection; and determining the liquid level from at least the evaluation temperature. The evaluation temperature is determined by monitoring the deflection and by defining an extreme value of the deflection as the evaluation temperature.

摘要： A monitor for the boiler water level in a boiler tube extends from the upper portion of the steam drum to the lowest water drum, header, or the like, and sensors are placed along its length which are responsive to the presence or absence of liquid water at the respective elevation. The condition of the various sensors can be utilized to read out the level of water in the system. The tube can be an external equalizer tube that extends between two extreme elevations, or can be a plurality of segments each extending for only a portion of the total height.
