Question

A rotary kiln incinerator is going to have an average energy release rate of 1,000,000 kJ/m²-hr in the combustion chamber. It is anticipated that the incinerator will be used to incinerate 2000 kg/hr of solid waste. The heating value (specific energy content) of the waste is 17,000 kJ/kg. The internal diameter of the kiln is 2.5m. Design the size of the incinerator in terms of volume and length.

Answer 1

sel Giv liven D- Joom fr=17000k/kg oook/m3 ho g = 10000ooks M=2000 kg/ho. From energy Balonce. Ov=MH 10V- 2000x 17000 V = 17X2 x 10 100 V = 34 m3 D² L=34 2) L=34x4 3014x185) 16.929 m

using given data and energy balance we can find the required dimensions
