Hi Arnt, Just another couple of points to consider if you try your idea.
<Snip> So why not use the air from the engine cooling system and divert that cooling airflow into the dryer. Now you do not have any of the dew point issues, sparks, etc such as when using exhaust gases for drying energy. The engine cooling system would use ambient air from the room and blow it into dryer with virtually no potential to cause fires or overheating of any sort. The engine usually has a fan already in place so no new parts would be required. Or you could use both sources of heat energy to dry the wet feedstock. <Snip> 1. Most commercial generating sets have a fan blowing outwards away from the engine. 2. These types of fans are not pressure forming, so any back pressure from a drying bed would reduce the air flows proportionally to the resistance. 3. If you use this type of hot air recovery, then fit a plenum box on the front of the radiator and use a second pressurizing fan to feed the drier. 4. If you add a heat exchanger to the exhaust in the plenum, you get the best options for any basic clean heat recovery. I do have pen and ink drawings buried in the now very dusty office, not on computer, but will have a look and see if I can post them within a few days. Regards, Doug Williams.
