Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional burners with pipes are used to heat the furnace chamber, then heating function is provided, but uniform temperature distribution cannot be achieved and scaling occurs on the pipes
Solution Approach 1:
The patent removes the conventional pipe structure from the furnace chamber and replaces it with a porous burner plate that distributes hot gases directly through its surface. This extraction of the pipe function eliminates the scaling problem while maintaining the heating function, as the porous plate allows direct contact with hot gases without forming a protective oxide layer.
Solution Approach 2:
The patent employs a porous burner plate that distributes hot gases uniformly through its porous structure. The porous material allows hot gases to pass through and distribute evenly across the furnace chamber, achieving uniform temperature distribution while avoiding the scaling issues of conventional solid pipes. The porous structure prevents direct contact between the heating element and the hot medium, eliminating scaling.
2Temperature
If multiple pipes are distributed in the furnace chamber to achieve uniform temperature, then temperature distribution improves, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the function of multiple distributed pipes into a single porous burner plate. Instead of requiring multiple separate pipe structures, the porous plate integrates the gas distribution function across its entire surface, achieving uniform temperature distribution with one unified component rather than multiple complex pipe arrangements.
Solution Approach 2:
The porous burner plate serves multiple functions simultaneously: it acts as the heating element, the gas distribution system, and the temperature control mechanism. This multi-functionality replaces the need for multiple specialized pipe components, simplifying the overall device structure while maintaining uniform temperature distribution capability.
3Object-affected harmful factors
If pipes are shielded to reduce radiant heat, then thermal radiation is reduced, but accessibility for servicing becomes difficult
Solution Approach 1:
The patent removes the pipe structure that requires shielding and servicing entirely, replacing it with a porous burner plate that is inherently resistant to thermal radiation and scaling. This extraction eliminates the need for shielding components and maintains easy accessibility for maintenance, as the porous plate can be easily accessed and serviced without requiring removal of shielding structures.
4Power
If conventional burners are used, then heating function is provided, but frequent pipe replacement is required due to scaling
Solution Approach 1:
The porous burner plate prevents scaling by allowing hot gases to pass through its porous structure without direct contact with the material surface. This prevents the formation of oxide layers that would require frequent replacement, extending the service life of the heating component while maintaining effective heating function.
Solution Approach 2:
The patent converts the potentially harmful effect of hot gases contacting the heating element (which causes scaling) into a beneficial distribution mechanism. The porous structure allows the hot gases to pass through and distribute heat uniformly, transforming what would be a scaling problem into an effective heat distribution solution that extends component life.

This configuration ensures consistent and controlled heat distribution, reduces wear and maintenance, and allows for more compact, cost-effective furnace systems with improved quality and efficiency, enabling uniform temperature control within the desired temperature range.
Implementation Method 1
Convection heat is usually provided for this purpose. The fan wheel is equipped with a double fan wheel, so that the hot medium generated by the burner is directly absorbed by one part of the fan wheel and distributed by the other part.
Implementation Method 2
a surface pore burner (20) which is arranged above a fan wheel (30)... for burning a gas/air mixture (21)
Implementation Method 3
The hot medium generated by the burner is directly absorbed by one part of the fan wheel and distributed by the other part... the hot medium can be distributed much faster and more evenly
