Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In gasified-gas generation systems, the combustor overheats when the system size is enlarged to increase gas production, leading to fluid medium dissolution and increased costs due to the need for high-temperature-resistant materials, and reducing the residue introduction to prevent overheating results in insufficient gasified gas production.
Innovation Solution
A gasified-gas generation system with a cooling mechanism that includes a loop seal to cool the fluid medium between the gasifier and combustor, using steam to regulate temperature and prevent overheating, while maintaining the required amount of gasified gas production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the size of the gasified-gas generation system is enlarged to increase gas production, then the amount of gasified gas increases, but the combustor overheats causing fluid medium dissolution and increased costs
Solution Approach 1:
A cooling mechanism is introduced as an intermediary component between the gasifier and combustor. This cooling mechanism includes a cooling medium circulation system that cools the fluid medium before it enters the combustor, thereby controlling the combustor temperature and preventing fluid medium dissolution while maintaining high gas production capacity
Solution Approach 2:
The temperature parameter of the fluid medium is actively controlled by adjusting the cooling mechanism's operation. By changing the temperature parameter of the fluid medium entering the combustor, the system prevents overheating and fluid medium dissolution while maintaining high productivity
2Temperature
If the amount of residue introduced into the combustor is reduced to prevent overheating, then the combustor temperature is controlled, but the amount of gasified gas production decreases
Solution Approach 1:
Instead of reducing residue introduction, a cooling mechanism is introduced as an intermediary to control combustor temperature. This allows the system to maintain high residue introduction levels for high productivity while actively cooling the fluid medium to prevent overheating and fluid medium dissolution
3Temperature
If high-temperature-resistant materials are used to withstand combustor overheating, then the combustor can handle higher temperatures, but the system cost increases
Solution Approach 1:
A cooling mechanism is implemented beforehand to prevent combustor overheating before it occurs. By cooling the fluid medium before it enters the combustor, the system avoids the need for expensive high-temperature-resistant materials, thereby reducing manufacturing costs while maintaining operational safety

AI summary
A gasified-gas generation system (100) includes: a combustor (110) that heats a fluid medium; a gasifier (140) into which the fluid medium heated by the combustor (110) is introduced and which gasifies a gasification material with heat of the fluid medium so as to generate a gasified gas; and a cooling mechanism (160) that cools the fluid medium that flows between the gasifier (140) and the combustor (110). The fluid medium circulates between the combustor (110) and the gasifier (140). The fluid medium and a residue of the gasification material are introduced from the gasifier (140) into the combustor (110), and the combustor (110) burns the residue to heat the fluid medium.
