摘要： A method of cleaning a gas inlet nozzle of an abatement burner combustion chamber. The abatement burner intermittently receives gas for combustion from a feed process. The nozzle comprises a cleaning mechanism including a movable cleaning member for physically removing unwanted deposits from the nozzle. The cleaning member is movable from a retracted first position wherein the cleaning member is outside a path of a flame associated with the nozzle, to a second cleaning position wherein the cleaning member is in a path of the flame associated with the nozzle. The method comprises the steps of:



a. identifying when the nozzle is out of use;
b. moving the cleaning member from the first position to the second position while the nozzle is out of use; and
c. returning the cleaning member to the first position before nozzle is in use.

摘要： A method of cooling an abatement apparatus for abatement of an effluent stream from a semiconductor processing tool includes: providing at least one modular cooling assembly having a cooling capacity; determining a cooling requirement of an abatement apparatus; and incorporating into the abatement apparatus a number of the modular cooling assemblies whose cumulative cooling capacity at least matches the cooling requirement of the abatement apparatus. In this way, multiple modular cooling assemblies may be incorporated into the abatement apparatus, each of which provides cooling capacity. The number of modular cooling assemblies can be selected to suit the cooling requirement of the abatement apparatus.

摘要： A waste organic solids burner integrated with an ethanol plant includes a burner receiving waste organic syrup, combustion air dryer exhaust and natural gas from the ethanol plant. A baghouse receives burner exhaust and extracts particulate matter and hot gas, which is sent to a waste boiler. Cool gas from the waste boiler is sent to a heat recovery scrubber, from which hot water is sent to the ethanol plant as an energy source.

摘要： The instant disclosure described a system and method to prevent the oxidizer overheating using cold side bypass for a VOCs treatment system with series rotor, which may be used in an organic waste air treatment system. The system is equipped with a Thermal Oxidizer (TO), a First Heat Exchanger, a Second Heat Exchanger, a third heat exchanger, a First Cold-Side Transporting Pipeline, a First Adsorption Rotor, a Second Adsorption Rotor, and a Chimney. There is a Cold-Side Proportional Damper installed between the First Desorption-Treated Air Pipeline and the First Cold-Side Transporting Pipeline, or it is installed on the First Desorption-Treated Air Pipeline. When the VOCs concentration becomes higher, the Cold-Side Proportional Damper can regulate the airflow to adjust the heat-recovery amount or concentration, when treating the organic waste air, it can prevent the TO from being overheated due to high oxidizer temperature, and protect it from Thermal Oxidizer shut-down.

摘要： A system and method controls a flow of vent gases to a combustion engine. The system includes an inlet for receiving the vent gases, a pressure relief device that enables the vent gases to escape to atmosphere when a pressure in the inlet exceeds a predetermined relief pressure, a flow-restricting orifice, and a back pressure regulator disposed downstream of the orifice. A shut-off valve disposed between the back pressure regulator and the air intake is set to only open when an intake pressure falls below a predetermined negative intake pressure.
