Potassium ferricyanide in pyrotechnical compositions

I've seen a short video here
https://www.youtube.com/watch?NR=1&feature=endscreen&...
where K3[Fe(CN)6] is used as a fuel in a very fast burning composition (as you can see very effective, you can also look on the same channel a test with KCLO3, etc). Though the exact oxidant/fuel ratio is given in video, I wonder how it should be calculated in general ? What should be the products of reaction KNO3+K3[Fe(CN)6] (K2CO3 or KCN; Fe, Fe2O3 or Fe3C?; etc)? If the products' composition is varying with regards of reagent ratio then how to figure out which composition is the "best" (put your definitions of the best). What if one uses NH4NO3 instead, also what you can say about such a fuel in general?
P.S. sorry if my question is confusing, I did my best trying to put down what I wanted to ask..
