摘要： Various embodiments include a combustion apparatus comprising: a facility for open- and/or closed-loop control of the apparatus; a combustion chamber; an actuator adjusting an air supply; and a combustion sensor in a region of a flame of the chamber. The controller stores a list of support points. A first air supply value is assigned to each support point. A drift test value and an index for ascertainment of a test result are assigned to each support point. The controller: generates a specified air supply; selects a support point as a function of the air supply; and decides on a test result using the index for the support point. To ascertain a test result: receives a signal from the combustion sensor; determines a new test result; ascertains a changed drift test value for the selected support point; and stores the changed drift test value as the drift test value.

摘要： The present disclosure deals with the regulation of fluid flows in the presence of turbulence. The teachings thereof may be embodied in regulating a fluid in a combustion device. For example, a method for regulating a burner device may include: requesting a flow of a fluid through a feed duct; assigning the requested flow to a setting of a first actuator; transmitting a first signal to set the first actuator; generating a mass flow signal representing an actual flow through the side duct; correlating the second signal to an actual value of the flow through the side duct; correlating the requested flow through the feed duct to a required flow through the side duct; generating a regulation signal with the regulator for the second actuator as a function of the actual value of the flow through the side duct and the requested value of the flow through the side duct; and transmitting the generated regulation signal to the second actuator.

摘要： The present disclosure deals with the detection of a blockage in the air-supply duct or flue of a burner assembly. In some embodiments, a method or system may detect blockages in the form of coverings and with burner assemblies to burn fossil fuels. For example, a control device may generate: a first air-control signal; a fuel-control signal by adjusting the actual values of the ionization current to the ionization-current setpoint; a setpoint increased by a specified amount from the ionization-current setpoint; and a changed fuel-control signal by adjusting the actual values of the ionization current to the increased setpoint in the case of a first air-control signal. The control device may evaluate the changed fuel-control signal generated based on the increased setpoint by comparing it with a specified maximum value and based on the evaluation, to detect a blockage. The control device may recognize the blockage based on the evaluation if the fuel-control signal generated using the increased setpoint exceeds the specified maximum value.

摘要： A facility for control of a combustion apparatus comprising: a memory storing a limit value and a correction factor; a communication connection to a sensor and an actuator; and a processor. The processor: receives an input signal from the sensor; uses the signal to form a measured value specifying a fuel air ratio, an air ratio, and/or an oxygen content; and loads the limit value and compares the measured value with the limit value. If the measured value is less than or greater than the limit value, the processor either loads the correction factor and determines a correction value as a function of the limit value, the correction factor, and the measured value, or loads the stored correction value from the memory, and then creates an output signal as a function of the correction value and sends the output signal to the actuator.

摘要： The present disclosure deals with the measurement of flows of a fluid in a combustion device. In particular embodiments, the teachings may be employed in the measurement of flows of fluids such as air in the presence of turbulence. For example, a combustion device may include: a burner; a side duct; and a feed duct. The side duct may include a mass flow sensor and a flow resistance element. The mass flow sensor detects a mass flow through the side duct. The flow resistance element subdivides the side duct. A connector of the feed duct comprises a Pitot probe. A first section of the Pitot probe projects into the feed duct and a sub area facing towards the outlet of the feed duct of the first section of the Pitot probe comprises the inlet of the Pitot probe.

摘要： A method is disclosed for diagnosing a valve assembly having valve members serially arranged along a flow channel of the valve assembly connecting at least one inlet and at least one outlet of the valve assembly. All of the serially arranged valve members of the valve assembly are opended to allow fluid to flow through the flow channel. The flow of fluid through the flow channel is measured by at least one sensor. At least one of the valve members is openend, and at least one sensor checks for fluid leakage caused by at least one faulted valve member. The at least one sensor may include a flow sensor, e.g., a mass flow sensor.
