摘要： A method for operating a combustion chamber is provided. The method includes introducing a fuel into the combustion chamber via a plurality of nozzles, each nozzle having an associated stoichiometry for an output end of the nozzle. The method further includes measuring the stoichiometry of each nozzle via one or more sensors to obtain stoichiometric data, and determining that at least one of a frequency and an amplitude of spectral line fluctuations derived from the stoichiometric data has exceeded a threshold. The method further includes adjusting the stoichiometry of at least one of the nozzles based at least in part on the stoichiometric data so as to maintain a flame stability of the combustion chamber.

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 device for mixing combustible gas and combustion air, hot water installation, and corresponding thermal mass flow sensor and method. The device includes an air line, a gas line with a control valve, a first measuring line connecting the air and gas lines, and a second measuring line connecting the first measuring line to the gas and/or air line, forming a three-way intersection. A thermal mass flow sensor includes first and second temperature sensors in the first measuring line, positioned respectively in a gas flow between the three-way intersection and the air line and in a gas flow between the three-way intersection and the gas line. A controller controls the control valve based on a difference, measured by the flow sensor, between mass flow rate of gas between the three-way intersection and the air line and mass flow rate of gas between the three-way intersection and the gas line.

摘要： Methods, devices, and systems for combustion resonance suppression are described herein. One device includes a memory, and a processor configured to execute executable instructions stored in the memory to receive a number of operating conditions of a burner, determine whether resonance characteristics are present in a combustion chamber housing the burner based on the number of operating conditions of the burner, and modify at least one of an air supply and a fuel supply to the burner upon determining resonance characteristics are present in the combustion chamber.

摘要： A control system for optimizing a chemical loop system includes one or more sensors for measuring one or more parameters in a chemical loop. The sensors are disposed on or in a conduit positioned in the chemical loop. The sensors generate one or more data signals representative of an amount of solids in the conduit. The control system includes a data acquisition system in communication with the sensors and a controller in communication with the data acquisition system. The data acquisition system receives the data signals and the controller generates the control signals. The controller is in communication with one or more valves positioned in the chemical loop. The valves are configured to regulate a flow of the solids through the chemical loop.
