Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If fuel gas containing carbon source (city gas or LPG) is used in conventional oxygen burners, then high-temperature combustion can be achieved, but large amount of carbon dioxide and soot are generated
Solution Approach 1:
The patent changes the chemical composition parameter of the fuel gas from carbon-containing hydrocarbons (city gas, LPG) to ammonia (NH3). This parameter change maintains the ability to achieve high-temperature combustion while eliminating carbon-based harmful emissions such as carbon dioxide and soot, directly resolving the technical contradiction between temperature achievement and harmful factor generation
Solution Approach 2:
The patent converts the previously harmful carbon-based fuel into ammonia, which contains no carbon. The combustion of ammonia produces high temperature without generating carbon dioxide or soot, effectively converting a harmful emission source into a clean energy source while maintaining the required thermal output for spheroidization
2Productivity
If fuel gas containing carbon source is used, then combustion can proceed, but soot is generated and may contaminate the inorganic spheroidized particles
Solution Approach 1:
The patent changes the fuel gas composition from carbon-containing to ammonia-based, fundamentally altering the combustion chemistry to eliminate carbon deposition. This ensures that the inorganic spheroidized particles remain free from soot contamination while maintaining efficient combustion for particle production
Solution Approach 2:
The patent eliminates the harmful effect of soot generation by switching to ammonia fuel, thereby converting a process that previously compromised particle purity into one that maintains high manufacturing precision and product quality
