Integrated Burner Assembly Without a Separate Fuel Manifold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern furnaces require multiple component parts for burner assemblies, leading to increased material and assembly costs, and there is a need to reduce the number of components without compromising efficiency.
Innovation Solution
A burner assembly design that eliminates the need for a fuel manifold module by integrating a single burner body with a common outlet for fuel and primary air, which is distributed to multiple burner heads, reducing the number of required components and facilitating a more efficient manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple component parts are used for burner assembly, then reliability and functionality are maintained, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent combines the fuel manifold module and burner body into a single integrated burner assembly. The fuel distribution channels are directly formed within the burner body structure, eliminating the need for a separate fuel manifold module. This merging reduces the number of component parts while maintaining the functionality of fuel distribution to multiple burners, thereby reducing device complexity without compromising reliability.
2Ease of manufacture
If multiple component parts are used for burner assembly, then functional requirements are met, but material costs and assembly costs increase
Solution Approach 1:
By integrating the fuel manifold functionality into the burner body, the patent reduces the total number of parts that need to be manufactured, stored, and assembled. This results in lower material costs due to reduced inventory requirements and lower assembly costs due to fewer components requiring assembly operations.
3Productivity
If multiple component parts are used for burner assembly, then fuel distribution functionality is ensured, but assembly time and labor costs increase
Solution Approach 1:
The integrated burner assembly eliminates the need to assemble a separate fuel manifold module with the burner body. The fuel distribution channels are pre-formed as part of the burner body structure, allowing the entire assembly to be installed as a single unit. This significantly reduces assembly time and labor costs while maintaining the fuel distribution functionality to multiple burners.

AI summary
A burner assembly for a fuel-fired heating furnace. The assembly comprises a burner body having an inlet opening to receive fuel delivered by a fuel control module, and, to receive an ambient source of primary air there-through. The furnace also comprises one or more burner heads connected to a common outlet opening of the burner body to receive a mixture of the fuel and the primary air.
