Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional flare tips are used to burn waste gas, then waste gas disposal is achieved, but visible flames and toxic gases are emitted causing environmental pollution
Solution Approach 1:
The flare tip is divided into multiple functional segments: a Coanda body for gas flow control, multiple baffles (first, second, and third baffles) for flame interaction and air mixing, and a segmented structure that allows each component to perform its specific function in reducing visible flames while maintaining disposal effectiveness
Solution Approach 2:
The baffles act as intermediary elements between the waste gas flow and the environment. These baffles interact with the flame front to promote complete combustion and mix air with the gas stream, serving as a mediator that transforms the harmful direct flame into a controlled combustion process that reduces visible flames and toxic emissions
2Productivity
If steam or air is injected at the flare tip to assist combustion, then combustion efficiency is improved, but device complexity and operational complexity increase
Solution Approach 1:
The Coanda body design enables the system to self-regulate gas flow and combustion without requiring external steam or air injection systems. The geometry of the Coanda body naturally controls the gas flow and promotes air mixing, allowing the system to achieve efficient combustion through its own structure rather than requiring additional complex injection equipment
3Quantity of substance
If the valve body is displaced further from the valve seat to handle higher pressure, then gas discharge capacity is improved, but exit velocity increases causing more intense flames
Solution Approach 1:
The system changes the parameters of gas flow by using the Coanda body to control flow velocity and direction, and by using baffles to mix air with the gas stream. This transforms the high-velocity discharge into a controlled flow pattern that maintains discharge capacity while reducing flame intensity through enhanced mixing and distributed combustion
