Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oxygen burners used for producing inorganic spheroidized particles generate a large amount of carbon dioxide and soot due to the use of fuel gases containing carbon sources like city gas or LPG, leading to environmental and product contamination issues.
Innovation Solution
The use of ammonia as a fuel gas in an oxygen combustion burner with a concentric multi-pipe structure, where ammonia and oxygen are premixed in small chambers to form efficient flames, reducing carbon dioxide generation and soot production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If fuel gas containing carbon source (city gas or LPG) is used in oxygen burner, then high-temperature flame can be obtained, 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-based fuels (city gas, LPG) to ammonia (NH3). This parameter change maintains the ability to generate high-temperature flame while eliminating carbon-based harmful emissions such as carbon dioxide and soot, directly resolving the technical contradiction between temperature generation and harmful factor production
Solution Approach 2:
The patent converts the previously harmful carbon-based fuel into ammonia, which contains no carbon source. By using ammonia as fuel, the harmful effects of carbon dioxide and soot generation are eliminated while the beneficial high-temperature flame generation is preserved, effectively transforming a harmful system into a beneficial one
