the makeup of a kiln. during the operation of the rotary kiln, flames can reach temperatures as high as 1900 c (3452 f) in order to heat raw materials to roughly 1500 c (2732 f). as a result, these materials become partially molten and undergo a series of physical and chemical reactions to become the primary constituent of cement.

aug 28, 2021 multiply 30 by 10,000 for your answer of 300,000 btus. as mentioned before, because of its rapid firing schedules, a raku kiln needs considerably higher btu/cf figures than regular studio kilns. the figures below will give you cycle times of 20-30 minutes. these are simple numbers that assume the kiln is well built and well designed.

as the rotary kiln rotates, that spot should read the same temperature for the entire circumference of the shell. for example, a temperature reading of 400 , 400 , 700 , 400 would likely indicate a failure in refractory. left untreated, this could lead to severe damage to the rotary kiln shell. the image shown here illustrates a refractory ...
