Thank you to everyone for responding. I really appreciate the sharing of knowledge as well as the links and leads. The reason for me posing this question is to experiment with any design that can potentially reach incinerating conditions which are 2,400 degrees fahrenheit. I am currently working with a gentlemen in India whom is trying to find an economical solution for burning plastic waste. We have found an environmental engineering company willing to test the exhaust of various items being burned in order to see what all types of waste can be burnt without leaving toxic pollutants.
I came across a video on youtube where Paul Wheaton is suggesting not to use steel in the core due to it having a melting point at 2,600 degrees fahrenheit. I am assuming that he has been able to produce a design that can achieve temperatures higher than the 2,600 since that is a concern of his. This is the type of design I am seeking. The cost will be very high for the environmental testing, so really we will only have one shot to get it right. The correct design will be everything, so whatever the system design needs to be and with whichever materials are needed.
All help is greatly appreciated!
