Solution Overview
Problem
Conventional gas generators face limitations in scaling up gas output due to inhomogeneous gasification medium supply, leading to uneven temperature distribution and inefficiencies in converting fuel into gas, which restricts their ability to achieve higher gas outputs.
Innovation Solution
A gas generation module with a reactor module and a supply unit featuring a feed tube that directs the gasification medium into the reactor cavity in the direction of gravity, utilizing multiple outlet openings with varying distances from the longitudinal axis to create a homogeneous gasification area, allowing for flexible scaling of gas output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional gasification medium supply designs are used, then the structure is simple, but the gas output is limited to approximately 1 MW and uniform temperature ranges cannot be achieved
Solution Approach 1:
The gasification medium supply is segmented into multiple supply pipes arranged around the reactor's perimeter, each equipped with multiple outlet openings at different radial distances. This segmentation allows the gasification medium to be distributed more uniformly across the gasification area, enabling scalable gas output beyond 1 MW while maintaining uniform temperature ranges.
Solution Approach 2:
Different outlet openings on the supply pipes are positioned at different radial distances from the reactor's central axis, creating locally optimized gasification zones. This local quality variation ensures homogeneous gasification across the entire reactor cross-section, allowing the system to scale to higher gas outputs while maintaining uniform temperature distribution.
2Manufacturing precision
If the gasification medium is supplied from a single location, then the supply structure is simple, but the gasification area is inhomogeneous
Solution Approach 1:
The single-point supply is segmented into multiple supply pipes distributed around the reactor perimeter. Each supply pipe contains multiple outlet openings at different radial positions, creating a multi-point supply system that achieves homogeneous gasification across the entire gasification area.
Solution Approach 2:
The supply system transitions from a single-point (0D) or single-line (1D) supply to a distributed two-dimensional array of outlet openings across the reactor cross-section. This dimensional expansion enables uniform gasification throughout the gasification area while maintaining a manageable supply structure.
3Temperature
If multiple supply pipes with outlet openings at different radial distances are used, then uniform temperature ranges are achieved, but the device complexity increases
Solution Approach 1:
Multiple supply pipes with differently positioned outlet openings are merged into a coordinated supply system where each pipe serves a specific radial zone. This merging creates a unified gasification medium distribution network that achieves uniform temperature ranges across the entire gasification area while managing complexity through systematic arrangement.
