Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high density of outer ring fire holes in burners leads to inadequate secondary air supplementation, resulting in high smoke concentration and low energy efficiency during combustion.
Innovation Solution
The incorporation of flow guide spaces at the junction between the circumferential side surface and top surface of the outer ring fire cover to guide secondary air to the outer ring fire holes, supplemented by secondary air channels and grooves, enhancing air supplementation and combustion efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the density of outer ring fire holes is increased, then the heating coverage is improved, but the secondary air supplementation becomes insufficient leading to high smoke concentration
Solution Approach 1:
The patent segments the fire cover into different functional zones: the outer ring fire cover with circumferential fire holes for heating coverage, and the addition of flow guide spaces that segment the air flow path to deliver secondary air specifically to the outer ring fire holes. This segmentation allows independent optimization of heating coverage and combustion efficiency.
Solution Approach 2:
The flow guide space acts as an intermediary structure that bridges the gap between the secondary air source and the outer ring fire holes. It guides and directs the secondary air flow to the fire holes, enabling sufficient air supplementation without reducing the number of fire holes, thus maintaining heating coverage while reducing smoke concentration.
2Area of stationary object
If the density of outer ring fire holes is increased, then the heating coverage is improved, but the energy efficiency decreases due to incomplete combustion
Solution Approach 1:
The flow guide spaces are designed to preliminarily direct and prepare the secondary air flow before it reaches the outer ring fire holes. This preliminary action ensures that sufficient secondary air is available at the fire holes in advance, promoting complete combustion and improving energy efficiency while maintaining high heating coverage.
Solution Approach 2:
The patent applies local quality by providing enhanced secondary air supplementation specifically at the outer ring fire holes through the flow guide spaces, while maintaining the high density of fire holes for overall heating coverage. This localized improvement in air supply quality enables complete combustion at each fire hole without compromising the global heating performance.
3Object-generated harmful factors
If flow guide spaces are added to guide secondary air, then the smoke concentration is reduced, but the device complexity increases
Solution Approach 1:
The flow guide spaces are merged with the outer ring fire cover structure, integrating the air guidance function into the existing fire cover component. This merging approach reduces device complexity by eliminating separate air guidance components while still achieving the goal of reduced smoke concentration through improved secondary air supplementation.
