Inlet Nozzle Assembly Standardized Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abatement apparatus require bespoke parts to accommodate varying effluent stream flow rates and types, leading to increased inventory and complexity due to varying delivery nozzle lengths, which affects the sizing of related components.
Innovation Solution
The inlet nozzle assembly features a mount with a standard height and a delivery nozzle composed of two bodies: a standard-length downstream body and a variable-length upstream body, allowing different nozzle lengths to protrude from the mount without altering the mount's height or chamber location, reducing the need for multiple parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bespoke parts are produced to accommodate varying effluent stream flow rates and types, then the abatement apparatus can be adapted to different conditions, but the inventory and complexity of parts increases
Solution Approach 1:
The mount is designed with a universal interface that can accommodate delivery nozzles of varying lengths through a single standardized mounting structure. The mount includes a receiving aperture and external threads that work with different nozzle configurations without requiring different mount designs, thereby reducing parts inventory while maintaining adaptability to various effluent stream conditions
2Productivity
If the length of the delivery nozzle is varied to suit different effluent streams, then the abatement performance can be optimized, but the sizing of related components such as the mount and housing must change
Solution Approach 1:
The delivery nozzle is segmented into two distinct components: a fixed-length downstream body that interfaces with the mount and combustion chamber, and a variable-length upstream body that connects to the effluent stream source. This segmentation allows the upstream body length to be varied for optimization while the downstream body and mount remain standardized, eliminating the need to redesign related components
3Shape
If different height plates or mounts are used for different length delivery nozzles, then the delivery nozzle can be properly positioned, but the inventory of parts required increases
Solution Approach 1:
The mount is designed as a universal component with a standardized height and configuration that can accommodate delivery nozzles of any length. The receiving aperture and external threads are positioned to ensure proper alignment with the combustion chamber regardless of nozzle length, eliminating the need for multiple mount heights and reducing parts inventory

AI summary
An inlet nozzle assembly includes: a delivery nozzle configured to deliver an effluent stream into an abatement chamber; and a mount configured to couple with an enclosure defining the abatement chamber, the mount being further configured to receive the delivery nozzle, wherein the delivery nozzle is configured to extend from the mount distal from the abatement chamber. In this way, the height of the mount and the location of the abatement chamber can remain fixed for different length delivery nozzles and different amounts of the delivery nozzle extend from the mount, dependent on the length of that nozzle.
