A method for using an apparatus to treat or utilize energy of a gaseous medium containing combustible components, the method comprising:
- providing the apparatus, the apparatus comprising:
- a pressure container;
- a burner including a heatable combustion chamber, the burner being arranged in a first portion of the pressure container, the first portion of the pressure container having a first longitudinal axis;
- a feed duct for feeding the gaseous medium into the heatable combustion chamber;
- a reaction chamber through which the gaseous medium can flow, the reaction chamber being arranged in a second portion of the pressure container, the second portion of the pressure container having a second longitudinal axis, the first longitudinal axis being transverse to the second longitudinal axis, the reaction chamber including an input chamber, a main chamber, and an output chamber, the input chamber being in fluid communication with the heatable combustion chamber, the main chamber being in fluid communication with the input chamber, the output chamber being in fluid communication with the main chamber and further being in fluid communication with a hot gas duct, thereby providing a flowpath for the gaseous medium from the heatable combustion chamber through the input chamber, through the main chamber, through the output chamber, and into the hot gas duct, the main chamber having an inlet opening for receiving the gaseous medium from the input chamber, the output chamber having an outlet opening for discharging the gaseous medium into the hot gas duct;
- and
- a hollow cylinder for guiding the gaseous medium in the main chamber of the reaction chamber, the hollow cylinder having an axis and extending through the main chamber in a longitudinal direction, the hollow cylinder including a radially outer surface, with respect to the axis of the hollow cylinder, and a radial inner surface, with respect to the axis of the hollow cylinder, and at least one wall opening extending through the radially outer surface and the radially inner surface, such that the gaseous medium can flow through the at least one wall opening, the at least one wall opening fluidly connecting the main chamber and the output chamber, the inlet opening of the main chamber being laterally offset relative to the axis of the hollow cylinder to provide angular momentum to the gaseous medium relative to the axis of the hollow cylinder as the gaseous medium flows from the input chamber into the main chamber, the inlet opening configured to cause the gaseous medium to flow in a cyclone flow about, and in contact with, the radially outer surface of the hollow cylinder within the main chamber, the cyclone flow having a cyclone axis extending in the longitudinal direction;
- the method further comprising:
- feeding the gaseous medium, via the feed duct, to the burner;
- converting the gaseous medium in the heatable combustion chamber of the burner to form an exhaust gas;
- feeding the exhaust gas from the burner into the reaction chamber;
- guiding the exhaust gas through the reaction chamber, and
- converting the exhaust gas in the reaction chamber, within a residence period of the exhaust gas in the reaction chamber, to form a treated exhaust gas;
- wherein a dispersion of the residence period of the exhaust gas in the reaction chamber is less than 50%.
