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.

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.
