Integrated Gasifier and Syngas Cooler Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gasification systems face inefficiencies due to the separate design of gasifiers and syngas coolers, which occupy significant space and increase production costs, as well as limitations in heat transfer efficiency.
Innovation Solution
An integrated vessel design that combines a gasifier and a radiant syngas cooler, with platen and membrane tubes extending from the cooler into the gasifier, facilitating enhanced heat transfer and reducing the overall length and material costs by sharing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a gasifier and syngas cooler are designed as separate components, then each component can be optimized independently, but the overall system occupies significant space and increases production costs
Solution Approach 1:
The patent combines the gasifier and syngas cooler into a single integrated vessel, where the cooler is positioned coaxially within the gasifier. This merging eliminates the need for separate external cooling systems, reducing overall system complexity and production costs while maintaining independent optimization capabilities through modular internal design
2Area of stationary object
If a gasifier and syngas cooler are designed as separate components, then maintenance and repair are easier for each component, but the overall system occupies significant space
Solution Approach 1:
The syngas cooler is nested coaxially within the gasifier vessel, with the cooler positioned inside the gasifier's cylindrical space. This nesting arrangement minimizes the system footprint by utilizing the internal volume of the gasifier, while the cooler can be designed as a removable module for maintenance purposes
3Use of energy by moving object
If platen tubes extend from the syngas cooler into the gasifier, then heat transfer efficiency is enhanced, but the structural complexity of the integrated vessel increases
Solution Approach 1:
Platen tubes serve as intermediary heat transfer elements that extend from the syngas cooler into the gasifier. These tubes act as thermal conduits, allowing efficient heat extraction from the syngas while the tubes themselves are designed as standardized, replaceable components that minimize structural complexity despite their penetrating configuration

AI summary
A system includes an integrated vessel that extends along a longitudinal axis. The integrated vessel includes a gasifier portion and a syngas cooler portion. The syngas cooler portion is disposed axially adjacent to the gasifier portion along the longitudinal axis. The integrated vessel also includes platen tubes that extend from the syngas cooler portion into the gasifier portion. The platen tubes are configured to route coolant through the integrated vessel.
