FLAMELESS THERMAL OXIDIZER FOR OXIDIZING GASEOUS EFFLUENT STREAMS CONTAINING HYDROGEN GAS
A method for oxidizing a waste stream having hydrogen therein includes flowing the waste stream with hydrogen into an oxidant stream for mixing the streams in a proportion for providing a mixture below lower flammability limits (LFL), including the LFL of hydrogen; and introducing the mixed streams into a ceramic matrix bed of a flameless thermal oxidizer maintained at a temperature above auto-ignition temperature of the mixture. A related apparatus is also provided.
Flameless thermal oxidizer for oxidizing gaseous effluent streams containing hydrogen gas
A flameless thermal oxidizer apparatus for a gaseous stream containing hydrogen includes a vessel containing a ceramic matrix bed; and a dip tube extending into the ceramic matrix bed, the dip tube including a first flow path for a first stream having hydrogen therein, and a second flow path for a second stream having an oxidant therein to be mixed with the first stream for introduction into the ceramic matrix bed. A related method is also provided.
EXHAUST GAS TREATMENT APPARATUS
An exhaust gas treatment apparatus for treating an exhaust gas discharged from an EUV (Extreme Ultra Violet) exposure equipment by combustion treatment to make the exhaust gas harmless is disclosed. The exhaust gas treatment apparatus includes a cylindrical combustion chamber configured to combust a processing gas containing hydrogen, and a processing gas nozzle and an oxidizing gas nozzle provided on the combustion chamber and configured to blow the processing gas and an oxidizing gas, respectively, in a tangential direction to an inner circumferential surface of the combustion chamber, wherein the processing gas nozzle and the oxidizing gas nozzle are positioned in the same plane perpendicular to an axis of the combustion chamber.
DUCTING SYSTEM
The present invention relates to a ducting system (100) for conveying a flow of a gaseous feed (110) comprising a combustible component from an inlet to at least one combustion module (12), the ducting system (100) utilising a combination of a sensor (C0) for measuring the concentration of the combustible component in the gaseous feed (110), a flame detector (F0, F1, F2, F3, . . . , Fn) a shut-off valve (6) and a flame arrestor (5) located in a flow path of the gaseous feed upstream of the shut-off valve (6) such that a measurement of a concentration of combustible material in the gaseous feed over a specified concentration by the sensor (CO) causes the shut-off valve (6) to be configured to the closed position for preventing flow of a gaseous feed comprising a combustible mixture of the combustible component from reaching an ignition source and/or detection of flame by the flame detector (F0, F1, F2, F3, . . . , Fn) causes shut-off valve (6) to be configured to the closed position for attenuating propagation of a flame towards the inlet.
BURNER MONITORING AND CONTROL SYSTEMS
Systems and methods for monitoring and controlling burning operations are provided. A method of one embodiment includes igniting oil or gas with a burner (282) during a burning operation and monitoring the burning operation with a camera (290). This monitoring of the burning operation can include acquiring image data for a flame (290) of the burner via the camera and analyzing the acquired image data to detect image features indicative of combustion of the oil or gas via the burner. Additional systems, methods, and devices are also disclosed.
Variable feed enclosed combustor system and method for its use
Disclosed herein are systems, apparatuses, and methods for using a sensed combustion zone temperature to continuously control combustion of a first (main) gas within an enclosed combustor. The combustor is in fluid communication with a first gas line carrying the first gas, a second gas line independent of the first gas line carrying a second (assist) gas having a higher heating value than the first gas, and air dampers providing draft or assist air. The first gas may be vapors from a production source or tank. A computer control system monitors the combustion zone temperature of the enclosed combustor as sensed by a sensor in electronic communication with the computer control system and controls the combustion zone temperature by changing a condition of a first gas line valve of the first gas line, a second gas line valve of the second gas line, and the air dampers.
THERMAL OXIDATION APPARATUS, CONTROL, AND ASSOCIATED METHODS
Example thermal oxidation apparatus, control, and associated methods are disclosed herein. An example apparatus includes a pump fluidly couplable to a pipe, the pump including a nozzle at a first end of the pump, a second end of the pump open to atmosphere, an air compressor fluidly coupled to the nozzle, and a thermal oxidizer disposed in the pump between the first end and the second end, the air compressor to provide air to the nozzle to cause suction of gas from the pipe, the thermal oxidizer to convert methane in the gas to carbon dioxide and water vapor to be vented from the second end of the pump.
APPARATUS AND METHOD FOR METHANE COMBUSTION OF RUMINANT ANIMALS
An apparatus and method are provided for reducing methane emissions from ruminant animals by combusting methane gas extracted from the rumen. The system comprises a conduit configured to transport methane from the animal's rumen to a combustion module mounted externally or implanted partially or fully in a subdorsal position. The combustion module includes a pressure-activated valve, air intake, ignition system, and combustion chamber enclosed by a heat-absorbing roof structure. A control unit monitors internal gas pressure and triggers a spark ignition circuit when combustion conditions are satisfied. An upward-facing camera inhibits ignition if flammable obstructions are detected above the module. A water-filled thermal buffer integrated into the chamber roof moderates exhaust temperature, reducing wildfire risk. Power is supplied by a solar panel and rechargeable battery. The system intermittently converts methane into carbon dioxide and water vapor, significantly mitigating the greenhouse gas impact of enteric fermentation in ruminant livestock.
