Team Vision for Problem Definition PhaseIn this phase, our team planned to interview our customer to decide on the primary purpose of the heat recovery design. After our discussion, as well as reviewing recommendations from last year's design, our team decided that we would be focusing our efforts on recovering heat for hot showers. Additionally, if the heating is consistent, we will try to pasteurize the water. We agreed with the customer understanding that this is not primary the focus of the project as the difficulty and short time frame may not lead to a successful design.
Project SummaryThe Kon Tiki Kiln is used to decompose unwanted organic materials into biochar, which is primarily used to improve agricultural yields. This kiln already creates biochar very well, but the customer determined that there was excess heat which could be recovered from the kiln. A previous senior design team (P16487) attempted to create an add-on that would dry tea leaves and pasteurize water, however the pasteurization was inconsistent.
The main goal of this project is to use the lessons learned from the previous senior design team to create a system that recovers waste heat to produce hot water for showers and/or radiant heating. Additionally, if we can accomplish water pasteurization temperatures, that would be an added bonus. The expected end result is a functioning prototype of our heat recovery system. The key constraints for this system is that it must not affect the biochar production of the kiln, it must cost less than $250, and that it must be easily operable by a farmer or homeowner.
This Use Case shows the process between a kiln operator in the community using the heat recovery system when operating the kiln.
Project Goals and Key DeliverablesExpected end result of the project, what the customer can expect to receive:
- A working prototype of our heat recovery system
- All design documentation for our heat recovery system
- Full technical write-up
- Completed project poster
- Completed EDGE website
- ImagineRIT presentation
