Modular Live Fire Burn Room with Replaceable Heat Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing live fire burn rooms made from Conex shipping containers are difficult and expensive to repair and replace due to damage from the heat generated by training fires, necessitating an improved design that is easier and less costly to maintain.
Innovation Solution
A modular live fire training system featuring a fire-rated inner structure installed within a large metal outer structure, such as a Conex shipping container, with a high-temperature insulation blanket and an air gap for thermal protection, along with a burn box and fuel source, allowing for controlled burns and easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special insulating tiles or panels are used to line the walls and ceiling of a live fire burn room, then the walls and ceiling are protected from heat damage, but the repair and replacement of damaged insulating components becomes difficult and expensive
Solution Approach 1:
The burn room structure is divided into modular components: an outer structure (shipping container), an inner structure (burn box with panels), and an insulation layer. This segmentation allows individual components to be easily removed, replaced, or repaired without affecting the entire structure, directly resolving the repair difficulty issue while maintaining heat protection through the layered design.
Solution Approach 2:
The inner structure (burn box) is nested within the outer structure (shipping container), and the insulation layer is disposed about the exterior of the inner structure. This nested arrangement provides thermal protection at multiple levels while allowing the inner burn box to be independently removed and replaced if damaged, eliminating the need to repair the entire structure.
2Reliability
If a fixed live fire burn room structure is used, then heat protection is provided, but maintenance and component replacement are costly and complex
Solution Approach 1:
The system transitions from a fixed structure to a dynamic, reconfigurable system where the inner burn box can be removed from the outer structure and the insulation layer can be adjusted. This dynamic design simplifies maintenance by allowing components to be easily accessed, inspected, and replaced without complex disassembly procedures.
Solution Approach 2:
The outer structure serves multiple functions: providing structural support, containing the inner burn box, and acting as a protective shell. The inner structure similarly provides both containment and a mounting surface for insulation. This multi-functionality reduces the number of separate components needed, thereby reducing maintenance complexity.
