摘要： A level control system for controlling the liquid level in a boiler drum is provided. The level control system uses an integration parameter when operating in a non-transient condition to provide a control signal into a flow control loop controlling a level control valve for the liquid level in the boiler drum. When a transient condition is identified by a predictive controller, the integration parameter is interrupted and a gain vector is generated to modify the control constants and optionally modify feedforward to adjust control signal into the flow control loop during transient operation of the level control valve.

摘要： An electronic cigarette vaporizer system operable in a ‘power’ mode to increase the amount of vapor produced by a vaporizer that forms part of the system, compared to normal, whilst monitoring the temperature of a heating element in the vaporizer to ensure that excessively high temperatures, associated with undesirable compounds in the vapor produced by the heating element, are not reached. The system includes a button or sensor that alters the operation of the heating element in such a way as to increase the vapor produced, compared to normal.

摘要： A method predicts an amount of wear that is expected to occur on the tubes of a steam generator as a result of vibration against another structure within the steam generator. The method includes determining a volumetric amount of material that has been worn from a location on a tube over a duration of time and employing that volume as a function of time to determine the volume of material of the tube wall that is predicted to be worn from the tube or another tube at a future time. The volumetric-based analysis enables more accurately prediction of the wear depth at a future time. This enables the plugging of only those tubes that are determined from a volumetric analysis to be in risk of breach at the future time, thus slowing the rate at which tubes of a steam generator will be plugged.

摘要： A boiler system includes a boiler having at least one heat exchanger having a surface on which a deposit may form. The boiler system further includes at least one retractable sootblower having a lance tube for carrying a high pressure fluid into the boiler. The lance tube is configured such that the high pressure fluid impacts the heat exchanger surface to effect a vibration thereof. The boiler system also includes at least one vibration measuring device coupled to the boiler system. The vibration measuring device is configured to measure the vibration of the heat exchanger surface, and the measured vibration indicates presence or absence of the deposit on the heat exchanger surface. The vibration measuring device may optionally detect a vibration caused by the release of the deposit from the surface of the heat exchanger or the impact of the released deposit with a surface in the boiler system.

摘要： A control unit includes a scale detection unit for detecting, while the a burner provides combustion, occurrence of clogging with scale in a tube of a heat exchanger, and an output unit for outputting a result of a detection by the scale detection unit, a storage stores information including a numerical value representing how many times a surface temperature of the heat exchanger measured by a temperature measuring unit exceeds at least one of a plurality of threshold values. While the burner provides combustion when the surface temperature measured by the temperature measuring unit exceeds at least one of the plurality of threshold values the scale detection unit adds a predetermined value to the numerical value in the storage and when the numerical value attains a defined value or more the scale detection unit detects occurrence of clogging with scale.

摘要： A sight glass system that simplifies the way a sight glass is cleaned and accessed during servicing a boiler by allowing someone to treat the boiler with cleaning chemicals without taking off the pressure release valve to pour in the boiler treatment. The cleaning process can now be achieved easily with the EZKleens Boiler Sight Glass system by taking off the service valve head cap and pour the treatment through the sight glass and into the boiler with the shut off valves open.

摘要： The present disclosure is directed to a system for determining scaling in a boiler. At least one sensor may monitor a boiler during operation and provide sensor data to a boiler monitoring module including a boiler scaling determination module that may determine an amount of scaling in the boiler. Example sensor data may comprise power input, a temperature of liquid in the boiler and an air temperature within an enclosure housing the boiler. The boiler monitoring module may determine thermal energy transfer to the boiler based on the liquid and enclosure temperatures. A machine learning engine may determine a rate of thermal energy transfer to the liquid in view of the power input, the rate of thermal energy transfer being evaluated by the machine learning engine to identify delay in the rate of thermal energy transfer that quantifies an amount of scaling in the boiler.
