Solution Overview
Problem
Current burner module designs are slow and laborious, relying on empirical methods to achieve optimal combustion conditions with low emissions of harmful compounds like CO and NOx, and lack flexibility in adapting other parameters for optimal operation.
Innovation Solution
The burner module design incorporates a specific dimensional parameter (R) calculated as the product of main height (H), pitch (P), and nozzle diameter (D), which when optimized (71 < R < 84 mm^3), effectively reduces NOx and CO emissions, simplifying the design process and ensuring optimal combustion conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If empirical design methods are used to optimize burner module geometry, then combustion performance can be improved, but the design process becomes slow and laborious
Solution Approach 1:
The patent establishes a mathematical relationship between key geometric parameters (main height H, pitch P, nozzle diameter D) through the dimensional parameter R = H×P×D. By defining the specific range 71 < R < 84 mm³, the invention transforms empirical trial-and-error into a direct parameter specification method, enabling designers to achieve optimal combustion performance without iterative prototyping and testing.
2Object-generated harmful factors
If burner module geometry is modified to reduce emissions, then harmful compound emissions decrease, but other parameters must be re-optimized
Solution Approach 1:
The invention defines a specific range for the dimensional parameter R (71 < R < 84 mm³) that simultaneously optimizes multiple performance criteria: reduction of harmful emissions (NOx and CO below specified thresholds) and maintenance of efficient combustion. This unified parameter approach ensures that when R is within the specified range, both emission reduction and combustion efficiency are achieved without requiring separate optimization of individual parameters.
3Reliability
If multiple geometric parameters are optimized independently, then combustion conditions can be improved, but the design complexity increases
Solution Approach 1:
The patent merges three critical geometric parameters (main height H, pitch P, and nozzle diameter D) into a single dimensional parameter R = H×P×D. This consolidation simplifies the design process by reducing the number of independent variables from three to one, while still capturing the essential geometric relationships that determine combustion performance and emission levels.
Solution Approach 2:
By defining the specific range 71 < R < 84 mm³, the invention provides a straightforward design criterion that eliminates the need for complex multi-parameter optimization. Designers can directly specify parameters that satisfy this relationship, greatly reducing design complexity while ensuring optimal combustion conditions and low emissions.
