Abstract: 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.

Abstract: A boiler is provided with: a boiler body in which the water level inside water pipes when combustion by a burner is stopped is lower than the upper ends of the water pipes; water supply means; control means which controls the water supply means depending on the water level in the boiler body; header water level detection means which detects a water level existing inside an upper header; and a downcast pipe. The control means performs first control for controlling the water supply means so as to lower a boiler body water level when the water level detected by the header water level detection means reaches a header set water level and second control for controlling the water supply means so as to raise the boiler body water level when the amount of drop in the boiler body water level reaches a predetermined amount after the first control.

Abstract: A water level control system for enhancing the controllability of the level of water retained in a steam drum. A water level control section of the system determines the volume of retained water in a steam-water separator from a detected steam flow rate signal by using a function operator and a first order lag circuit, determines a signal representing the mass flow rate balance of water in the steam-water separator by differentiating the volume of retained water with respect to time with a differentiator, generates a compensated signal by adding the signal to the difference between a detected feed water flow rate signal and the detected steam flow rate signal, and properly compensates a valve area demand for a feed water flow control valve.

Abstract: A software-based water level monitoring and control system, preferably for use with conventional steam boilers, is disclosed. The system includes software for monitoring and recording system functions, safety features, diagnostic testing histories, and other functions. The water level system is employed to monitor and/or regulate one or more operating parameters of the boiler, such as water levels within the boiler. In response to the boiler system testing of low-water cut-off, auxiliary low-water cut-off, and pressure vessel float operation and functionality, the software builds histories and other data compilations. The extensive electronic information permits a user that accesses the water level control system to, for example, view the data compilations and to monitor the status of the system. In this manner, real-time information, as well as the historical data, are available to accomplish the regulation of key parameters in the boiler. Other capabilities of the system include, via a computer terminal, setting up initial features and options as well as de-bugging of the boiler system. The system is used to prevent a catastrophic failure of a boiler, and ensure that the test procedures of the main and auxiliary units are being conducted and that the results are available and satisfactory for proper operation of the boiler.

Abstract: 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.
