Engineering Contradiction Analysis
1Power
If forced draft gas burners are used to provide heating capacity for large or moist textile webs, then the required heating capacity can be achieved, but energy efficiency deteriorates and operational costs increase
Solution Approach 1:
The patent combines an internal hot gas source (forced draft gas burner) with an external hot gas source (combined heat and power plant) to create a dual heat input system. This merging allows the dryer to utilize waste heat from external sources, improving energy efficiency while maintaining the required heating capacity for large or moist textile webs.
Solution Approach 2:
The invention converts waste heat from the external combined heat and power plant into a useful resource for the drying process. By capturing and utilizing this previously wasted thermal energy, the system improves overall energy efficiency and reduces operational costs while maintaining adequate heating capacity.
