Solution Overview

Problem

Conventional gas burners produce flames with poor uniformity due to high pressure and speed near the gas inlet and low pressure and speed far from the inlet, resulting in inconsistent combustion.

Innovation Solution

A vortex pressurized burner design featuring a gradually reduced volute flow passage and annular gas outlet passages, which reduces pressure differences and ensures uniform gas flow and ignition, preventing reverse gas flow to maintain consistent flame intensity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If gas is introduced into circular gas passages and jetted out from gas outlets, then gas flow is generated for combustion, but the flame uniformity is poor due to pressure and speed differences between near and far outlets from the gas inlet conduit

Engineering Contradiction:

Improveflame uniformityVSAvoidgas pressure distribution

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The volute flow passage cross-sectional area is gradually reduced from the gas inlet end to the outlet end, changing the geometric parameters along the flow path. This gradual reduction compensates for pressure losses and maintains more uniform gas pressure and flow velocity at all gas outlets, thereby improving flame uniformity across the burner surface

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The volute flow passage is divided into multiple segments along its length, with each segment having a slightly different cross-sectional area. This segmentation allows for progressive pressure equalization throughout the flow passage, ensuring that gas reaches all outlets with similar pressure characteristics

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If a conventional gas inlet conduit is used, then gas can be supplied to multiple outlets, but the gas pressure and speed vary significantly from near to far outlets causing inconsistent combustion

Engineering Contradiction:

Solution Approach 1:

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The design aims to create equipotential conditions for gas pressure throughout the volute flow passage by carefully controlling the cross-sectional area reduction. This ensures that all gas outlets operate under similar pressure conditions, achieving consistent combustion across the entire burner

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The design achieves more uniform flames by maintaining consistent gas pressure and speed across all outlets, enhancing flame uniformity and intensity through a one-way flow structure and spiral gas outlet arrangement.

Implementation Method 1

the cross-sectional shape of the volute flow passage is gradually reduced from the gas passage head end to the gas passage tail end... make a pressure difference of the volute flow passage from a gas passage head end to a gas passage tail end smaller

Methodology Applied

Scientific EffectPressure gradient: Pressure Gradient

Implementation Method 2

the gas passage tail end is cut off, so that a gas flow entering the volute flow passage via the gas passage head end can be stopped at the gas passage tail end from entering the gas passage head end

Methodology Applied

Scientific EffectFlow direction control:

Implementation Method 3

all of the plurality of gas outlet passages are arranged along an extending direction of the volute flow passage to form an annular gas outlet area... increasing the uniformity of circumferential combustion of flames

Methodology Applied

Scientific EffectAnnular flow distribution:
