Congratulations on your stove design. I can understand the thrill of creation you must feel.+cleancoalflexfuel+ wrote:My favorite I tell my sons is this: How you do something determines the success.You must have a lot of patience and put hours of thought into your project, turn off the TV turn off the music, rethink and rethink,study than when it works well then go study what others say,dont fill your mind with the proven but be different in every way. You cannot invent something thinking exactly like the next person..You must see potental and be able to over come though design.My favorate line as a young man was, "they didnt engineer it right" Skip
Achieving a long burn time is easy to do. What is hard to do is to make that long burn time efficient. What is the Co2 reading and also the smoke number on the Shell scale? What kind of coal are you burning? Is your stove natural draft from a chimney or are you using a blower of some kind?
I don't think the answers would jeopardize the confidentiality of your design and would help to satisfy the curiosity many feel.
