Removable Nozzle for High-Temperature Gasification Burner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-temperature burners used in gasification reactors have nozzles that degrade quickly, requiring costly and time-consuming refurbishment, often necessitating multiple burners to be maintained in inventory due to the complexity and expense of shipping and repairing the entire burner.
Innovation Solution
A high-temperature burner design with a removable nozzle that can be replaced on-site, featuring a body and nozzle with attachment elements, such as bolts, allowing for fluid communication and easy replacement without refurbishing the entire burner, enabling quick maintenance and reducing downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the nozzle is made detachable for easy replacement, then the ease of repair is improved, but the device complexity increases due to additional attachment elements
Solution Approach 1:
The burner is divided into separable components: a body and a detachable nozzle. The nozzle can be removed and replaced independently from the body through a flange interface, allowing quick replacement without replacing the entire burner assembly.
Solution Approach 2:
The nozzle is extracted as a separate replaceable component from the burner body. When the nozzle degrades, only the nozzle needs to be removed and replaced, while the body remains in service, significantly reducing repair time and complexity.
2Reliability
If the entire burner is refurbished when the nozzle fails, then the reliability is maintained, but the loss of time increases due to months-long refurbishment processes
Solution Approach 1:
The burner system is segmented into a permanent body and a replaceable nozzle. This allows the body to remain in service while only the degraded nozzle is replaced, reducing downtime from months to a fraction of that time.
Solution Approach 2:
The degraded nozzle is discarded and replaced with a new or refurbished nozzle, while the burner body is recovered and kept in service. This selective replacement approach maintains reliability without requiring complete burner refurbishment.
3Productivity
If multiple burners are maintained in inventory to prevent downtime, then the productivity is ensured, but the quantity of substance (inventory costs) increases
Solution Approach 1:
By segmenting the burner into replaceable nozzle and permanent body components, the system reduces the need for multiple complete burner inventories. Only nozzles need to be stocked for quick replacement, reducing inventory requirements while maintaining continuous productivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables on-site nozzle replacement, reducing maintenance time and inventory needs, and lowering costs associated with burner refurbishment and handling, thereby improving operational efficiency and reducing the need for extensive inventory management.
Implementation Method 1
a generally frustoconically shaped cooling jacket comprising at least one nozzle coolant conduit, wherein the cooling jacket at least partially surrounds at least a portion of the nozzle passage

AI summary
A burner comprises a body, a nozzle, and at least one attachment element for removably attaching the nozzle to the body. The body defines an oxidant inlet, a feedstock inlet, a body outlet, and one or more passages for conveying the oxidant from the oxidant inlet to the body outlet and for conveying the gasification feedstock from the feedstock inlet to the body outlet. The nozzle defines a nozzle inlet and a nozzle outlet, wherein the nozzle inlet is configured to receive the oxidant and the gasification feedstock from the body outlet and the nozzle outlet is configured to discharge the oxidant and the gasification feedstock into the reaction chamber. The at least one attachment element removably attaches the nozzle to the body such that the nozzle inlet is in fluid flow communication with the body outlet when the nozzle is attached to the body.
