Heat Exchange Solutions to Improve Shop Comfort

AI Thread Summary
A stainless steel elbow used as a heat exchanger for a gravity feed pellet burner has proven ineffective in transferring heat into the shop. The pellet burner itself operates efficiently with an eight-hour burn time, but maximizing heat recovery remains a challenge. Significant heat radiates from the pellet burner’s metal housing, prompting plans to add a plenum for better heat distribution. The project aims to create an external firebox that effectively transfers heat indoors. Suggestions for low-cost, easy-to-fabricate heat recovery solutions are welcomed.

Heat Exchanger?

Greetings, after two days of testing my idea of using a stainless steel elbow as a heat exchanger and blowing the hot air into the shop does not work. On the plus side the gravity feed pellet burner works very well. I did find that considerable heat is radiating from the top of the metal box housing the pellet burner. I am planning to add a plenum to the top of the housing and vent that into shop, hopefully this will recover more heat. If anyone has any ideas how I can improve heat recovery and transfer that heat into the shop please let me know. Best regards

What is it you are trying to do? You seem to assume we have prior knowledge of your device and goals.
 


Greetings, I created a gravity feed pellet burner. The pellet burner works very well. It has a 8 hour unattended burn time. My challenge now is to recover as much heat from the pellet burner and transfer that heat into the building. My first attempt using a stainless elbow positioned over the flame to heat the air inside the vent has failed. Basically the project is to have a fire box outside the building and then try to recover as heat as possible and transfer that heat to inside the building. I am looking for ideas that are low cost and easy to fabricate. I found some videos on youtube showing heat recovery systems. If anyone has any other ideas please let me know.
Best regards.

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
