biomass, as well as oxy-fuel and oxy-coal combustion technologies. CFD modelling has been used to investigate the co-combustion of different fuels in cement rotary kiln [1-8]. One study [1] found that annulus fuel feeding results in faster devolatilization and char combustion than central tube fuel feeding.
The rate of combustion is controlled by regulating the amount of oxygen allowed into the burn and is stopped by excluding oxygen before the charcoal itself begins to burn. In South Africa charcoal is widely produced, using the direct method, in small metal or masonry kilns. The indirect method uses an external source of heat to cook the …

The kiln is set at a slight slope to assist in moving material through the drum. Direct-fired kilns utilize direct contact between the material and process gas to efficiently process the material. Combustion can occur in a combustion chamber to avoid direct flame radiation, or the flame can be directed down the length of the kiln.
The combustion state of the fifth frame of the input sequence was shifted backward in time and taken as the target prediction state, i.e., the future combustion state of the rotary kiln. As shown in Fig. 6, when the window width was 9, the average precision of the final fine-tuned CRNN model reached 93.26%.
