Vertical Furnace Radiant Section Stacking for Space Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Furnace systems used in delayed coking processes face space constraints, limiting the number of radiant sections that can be placed in a given area, resulting in suboptimal design and increased capital investment.
Innovation Solution
The arrangement of at least one upper radiant section above a lower radiant section, combined with a convection section, creates an exhaust corridor that reduces the overall area required for the furnace system's construction, allowing for more radiant sections to be placed in a smaller space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radiant sections are arranged in a side-by-side configuration, then the furnace system can accommodate multiple radiant sections, but the area required for construction increases
Solution Approach 1:
The patent transitions from a traditional side-by-side horizontal arrangement of radiant sections to a vertical stacking configuration where radiant sections are arranged one above another. This dimensional change from horizontal to vertical space utilization allows multiple radiant sections to be accommodated within a smaller footprint area, directly resolving the contradiction between accommodating more radiant sections and reducing construction area
2Adaptability or versatility
If multiple convection sections and radiant sections are included in the furnace system, then the heating capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple radiant sections and convection sections into a single integrated vertical structure where they share common support frameworks, exhaust corridors, and spatial organization. This merging approach maintains the enhanced heating capability of multiple sections while reducing overall device complexity through shared structural elements and streamlined configuration

This configuration enables the construction of a furnace system in a smaller area, reduces capital investment, and improves flexibility in heating processes, while maintaining efficient heat transfer and extending the run length of radiant sections by optimizing the flux profile.
Implementation Method 1
the residual oil feed is heated to the cracking temperature in the at least one radiant section
Implementation Method 2
The residual oil feed is pre-heated in the at least one convection section prior to being conveyed to the at least one radiant section

AI summary
A furnace system includes at least one lower radiant section having a first firebox disposed therein and at least one upper radiant section disposed above the at least one lower radiant section. The at least one upper radiant section has a second firebox disposed therein. The furnace system further includes at least one convection section disposed above the at least one upper radiant section and an exhaust corridor defined by the first firebox, the second firebox, and the at least one convection section. Arrangement of the at least one upper radiant section above the at least one lower radiant section reduces an area required for construction of the furnace system.
