A heating apparatus for an exhaust train comprises a flow-conducting device for guiding an exhaust gas flow along a flow path; a burner that is arranged outside the flow-conducting device and that is configured to generate heating gases during the combustion of a fuel; and a supply device that is configured to supply the heating gases generated by the burner to the exhaust gas flow, which is guided through the flow-conducting device, via a heating gas inlet that is formed in a wall of the flow-conducting device. The supply device has a channel that is fastened to an outer side of the flow-conducting device in a manner covering the heating gas inlet and open towards it, wherein the channel extends along a peripheral direction running around the flow path and in so doing engages around the flow-conducting device while forming an interruption.

Devices, systems, and methods for carbon capture optimization in industrial facilities are disclosed herein. An example carbon capture process involves cooling a flue gas stream using at least one gas-to-air heat exchanger disposed upstream of a carbon dioxide (CO2) absorber. Another example carbon capture process involves heating a heat medium for solvent regeneration and CO2 stripping using a fired heater and/or using at least one waste heat recovery unit.

An exhaust-gas burner for an exhaust-gas system of a motor vehicle includes a combustion chamber, which is surrounded by an outer wall, for a channel section in an exhaust-gas system. A dosing unit is provided for the controlled feed of a fuel into the combustion chamber. An ignition unit is provided for the ignition of a combustible mixture in the combustion chamber. A cooling circuit is provided for the exchange of heat with the dosing unit, and is arranged within the outer wall of the exhaust-gas burner.

An exhaust gas heater for an exhaust gas system of a combustion engine includes a carrier and at least one heating conductor through which a current flows. The heating conductor is mounted on the carrier. The heating conductor is provided via separation from a metal flat material blank. A method of making an exhaust gas heater includes a step of separating the heating conductor from the metal flat material blank.

Exhaust plume abatement systems and methods are provided. A representative system, which is configured for use with a heating appliance, incorporates: a housing defining an interior chamber; an exhaust gas inlet configured to receive exhaust gas from the heating appliance; a first heat exchanger, disposed within the interior chamber; a dilution air inlet configured to receive dilution air from outside the housing; an exhaust gas outlet communicating with the interior chamber; wherein the interior chamber is configured to receive the exhaust gas from the exhaust gas inlet and the dilution air to form low humidity exhaust gas, which exhibits a lower humidity than the exhaust gas received from the heating appliance; and wherein the exhaust gas outlet is configured to output the low humidity exhaust gas with no visible exhaust plume.

A method for improving effectiveness of a steam generator system includes providing a steam generator system including a steam generator vessel, an air supply system and an air preheater. The air supply system is in communication with the steam generator vessel through the air preheater and the steam generator vessel is in communication with the air preheater. The air supply system provides a first amount of air to the air preheater. At least a portion of the first amount of air is provided to the steam generator vessel. A flue gas mixture is discharged from the steam generator vessel. At least a portion of the flue gas mixture flows into the air preheater. SO.sub.3 in the flue gas mixture is mitigated before the flue gas mixture enters the air preheater.

Several embodiments of the present technology are directed to the removal of one or more air pollutants using cooling and/or calcium-containing particles. In some embodiments, a method for removing air pollutants comprises flowing a gas stream having calcium-containing particles and one or more of mercury or hydrochloric acid molecules, and cooling the gas stream, thereby causing at least a portion of the calcium-containing particles to adsorb to the mercury and/or hydrochloric acid molecules in the gas stream. The method can further comprise, after cooling the gas stream, filtering the gas stream to remove at least a portion of the calcium-containing particles having adsorbed mercury and hydrochloric acid.
