Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional burners face difficulties in atomizing and efficiently combusting liquid fuels with small particles due to clogging issues, which restricts their energy usage and functionality.
Innovation Solution
A novel atomization jet design featuring a Y-shaped mouth and effervescent part, utilizing tangential nozzles for air input to create a rotational flow that cleans the mixing chamber and outlet nozzle, and a labyrinth sealing mechanism to prevent clogging, allowing for effective atomization and combustion of fuels with small particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional atomizer jets are used to atomize liquid fuel with small particles, then fuel atomization is achieved, but the small particles clog the atomizer outlet jets causing burner failure
Solution Approach 1:
The harmful small particles are extracted from the fuel stream by the effervescent flow before reaching the outlet jet. The air bubbles rise through the fuel, carrying particles with them, preventing particle accumulation and clogging at the jet outlet while maintaining continuous fuel atomization capability
Solution Approach 2:
Air bubbles serve as an intermediary medium between the liquid fuel and the outlet jet. The effervescent flow created by tangential air nozzles introduces air as a mediator that interacts with fuel particles, facilitating their removal from the fuel stream before atomization occurs at the jet outlet
2Use of energy by moving object
If fuel is atomized to increase energy usage, then combustion efficiency improves, but small particles in waste fuel cause jet clogging
Solution Approach 1:
The effervescent separation action is performed preliminarily before the fuel reaches the atomizer outlet jet. By creating air bubbles that rise through the fuel in the effervescent chamber, particles are removed in advance, preventing subsequent clogging while allowing the atomized fuel to maintain high energy utilization in combustion
Solution Approach 2:
The harmful effect of air bubbles interfering with fuel flow is converted into a beneficial separation mechanism. The air bubbles, which might seem to disrupt fuel atomization, actually serve to carry particles away from the fuel stream, preventing clogging and enabling continuous efficient operation of the atomizer with waste fuels containing particles
