Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy fuel oils used in gas turbines and boilers contain high concentrations of undesirable substances like sulfur, nickel, and vanadium, which produce harmful emissions when burned.
Innovation Solution
A fuel treatment system utilizing hydrodynamic cavitation reactors combines fuel with water to crack the fuel and produce radicals that oxidize and remove these substances, allowing for their separation from the fuel using a separator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If heavy fuel oil is used as fuel, then energy supply is maintained, but harmful emissions (sulfur, vanadium, nickel) increase
Solution Approach 1:
The fuel undergoes preliminary treatment through hydrodynamic cavitation before combustion. The cavitation process pre-oxidizes the fuel and converts harmful substances into separable compounds, preventing them from being emitted during combustion. This preliminary action removes sulfur, vanadium, and nickel from the fuel before it is burned, allowing energy supply while eliminating harmful emissions.
2Object-generated harmful factors
If hydrodynamic cavitation is applied to treat fuel, then harmful substances are removed, but system complexity increases
Solution Approach 1:
The system uses hydrodynamic cavitation, which is a hydraulic phenomenon, to treat the fuel. By utilizing water injection and hydrodynamic forces to create cavitation bubbles that collapse and oxidize harmful substances, the system avoids complex chemical treatment apparatus. The hydraulic approach simplifies the overall system while effectively removing sulfur, vanadium, and nickel from the fuel.
3Manufacturing precision
If multiple separation stages are used, then purification efficiency is improved, but device complexity increases
Solution Approach 1:
The purification process is segmented into distinct functional stages: first hydrodynamic cavitation reactor for initial oxidation and separation, then a second reactor for further treatment of separated components. This segmentation allows each stage to specialize in specific purification tasks, achieving high purification efficiency while maintaining manageable system complexity through modular design.
