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

VSEngineering 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

Engineering Contradiction:
Improvefuel atomization efficiencyVSAvoidburner functionality
Core Design Contradiction:
ProductivityVSReliability

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

Inventive Principle:
Principle #2Taking out (Extraction)

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

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improvefuel energy utilizationVSAvoidjet clogging by particles
Core Design Contradiction:
Use of energy by moving objectVSObject-generated harmful factors

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

Inventive Principle:
Principle #10Preliminary action

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

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
