The invention relates to a method for the thermal disposal of pollutants in industrial gases, wherein, in order to generate a flame for burning the pollutants, a fuel gas and oxygen are fed into a combustion chamber (19) of a burner (1), where they are then ignited, wherein a diluent gas is fed in in order to reduce the calorific value of the gas mixture relative to the fuel gas, while the throughput of the diluent gas is regulated as a function of the composition of the industrial gas in order to adapt the gas mixture consisting of diluent gas and fuel gas. The invention also relates to a burner (1) for generating a flame (2) in a combustion chamber (19) for burning pollutants in an industrial gas, and to a waste-gas treatment device having at least one burner (1) arranged in a combustion chamber (19).

A heater comprises a combustion chamber and a jacket extending about the combustion chamber. There is a fan having an output which communicates with the combustion chamber to provide combustion air. There is also a fuel delivery system having a variable delivery rate. A burner assembly is connected to the combustion chamber. The burner assembly has a burner mounted thereon adjacent the combustion chamber. The burner receives fuel from the fuel delivery system. There is an exhaust system extending from the combustion chamber. An oxygen sensor is positioned in the exhaust system to detect oxygen content of exhaust gases. There is a control system operatively coupled to the oxygen sensor and the fuel delivery system. The control system controls the delivery rate of the fuel delivery system according to the oxygen content of the exhaust gases.

A system for electronically controlling a vent damper for a gas oven.

A process and apparatus for regenerating a spent acid stream or other stream, such as a spent acid stream or other stream containing sulfur, by decomposing the spent sulfuric acid stream and/or other sulfur-containing streams to recover sulfur dioxide from the stream. Also provided is a process for preparing sulfuric acid from the sulfur dioxide recovered by the apparatus and process.

A method of monitoring a flame during gas combustion in a combustion chamber (10). A heating unit (1) has an evaluation unit, an extraction line (11) and a sensor (12). The sensor (12) is arranged in the extraction line (11) to detect thermal substance properties of the gas. Thus, it is determined if it is ambient air (B), a non-combusted fuel-air mixture (C) or particularly the hydrogen-air mixture, or a waste gas (A) generated during combustion. The sensor (12) transmits a recorded measured value to the evaluation unit. The evaluation unit uses the measured value to determine whether ambient air (B), the non-combusted fuel-air mixture (C), or waste gas (A) is flowing through the extraction line (11) and thereby determines whether the flame is burning or extinguished.

A burner control system for improving burner performance and efficiency may determine fuel and air channel or manifold parameters. Determination of parameters may be performed with a sensor connected across the air and fuel channels. A signal from the sensor may control the parameters which in turn affect the amounts of fuel and air to the burner via a controller. Parameter control of the fuel and air in their respective channels may result in more accurate fuel and air ratio control. One or more flow restrictors in fuel and/or air bypass channels may further improve accuracy of the fuel and air ratio. The channels may be interconnected with a pressure or flow divider. Byproducts of combustion in the exhaust, temperatures of gas and air, flame quality and/or other items may be monitored and adjusted with control of the fuel and air ratio for optimum combustion in the burner.

A method and an assembly for controlling an internal combustion engine having multiple burners is provided. Combustion measurement data is collected in a burner-specific manner for each burner and assigned to a burner identification identifying the respective burner. Performance measurement data of the internal combustion engine is also collected and used to determine a performance value. A machine learning model is trained by means of the combustion measurement data, the associated burner identifications and the performance measurement data, to generate burner-specific control data which optimizes the performance value when the burners are actuated in a burner-specific manner using the control data. The control data generated by the trained machine learning model is output for the burner-specific actuation of the burners.

A heating device as well as a method for the operation thereof. The heating device has an outer housing that surrounds an installation space. The components of heating device are arranged inside or on the outer housing, particularly a burner unit, a fan, a fuel valve and as an option a circulation pump. At least one of these units comprises at least one electrical and/or electronic component. On one or more of the anyway present electrical and/or electronic components at least one gas sensor is arranged on the outer housing and/or inside the installation space, particularly on a support or a circuit board of the respective electrical and/or electronic component. The at least one gas sensor is configured to create a sensor signal that describes the presence and/or concentration of at least one gas component in the atmosphere. Based thereon leakages, faults, undesired backflow, etc. can be determined. Thereupon a respective measure can be initiated, e.g. the output of a warning message and/or suction of the atmosphere by means of fan.

Systems and methods iteratively solve a fired-systems model of the process heater based on fuel information, a target heat release of the plurality of burners, ambient air information, and available airflow at each of the plurality of burners to identify optimized burner air register settings to achieve a target global excess oxygen level to be sensed by the oxygen sensor. The optimized burner air register settings may be output to a heater controller of the process heater for control of the process heater.
