Latest Patents
William F. Harder's latest patents include the following notable designs:
1. **Air Preheater Heat Transfer Surface** - This innovative air preheater features heat transfer elements designed with a first series of corrugated elements. These elements have longitudinally oriented corrugations that enhance heat transfer by creating multiple boundary layer breaks. The addition of notched plates positioned adjacent to these corrugated elements further optimizes the heat transfer process, allowing for straight-line passages through the elements, which improves overall efficiency.
2. **Rotary Regenerative Air Preheater Basket Sealing** - In this patent, Harder introduced an improved element basket for rotary air preheaters. This design includes a solid steel sheet that is tack-welded to cover one side of the basket and is bent back to create a bias against the rotor wall. This mechanism effectively fills gaps and prevents gas or cold air from bypassing the heat transfer elements, thus enhancing the performance of the heating system.
