Calcium looping has been used for CO2 capture. High‐temperature calcination is needed to decompose CaCO3. To reduce the energy consumption of CaCO3 decomposition in calcium looping, a CaCO3 decomposition system integrating a rotary kiln, waste heat recovery by a single‐atom fluid, and the CaO carbonization process is proposed. The waste heat recovery produces the electric field to intensify CO2 capture. A computational fluid dynamics model is established to study the effects of various parameters on the performance of the rotary kiln. It is found that the electric field enhances the mass transfer and CO2 capture. The system temperature is increased, resulting in significantly enhanced CO2 capture with increased feeding temperature. This provides an alternative way for CO2 capture.

Significant researches have been enthusiastic throughout the last centuries for supersonic and hypersonic flight conditions for enabling flights many times faster than sound. This current work presents the performance analysis of supersonic combustor interface and flow construction through a scramjet engine with a Planar-shaped strut injector (PSSI) at the supersonic Mach. An important aspect of this study is the discovery of the fuel mixing mechanism inside the combustion chamber with PSSI. Mixing and combustion performance can be enhanced by the novel PSSI configuration. The scramjet configuration is incorporated with the supersonic inlet air temperature of 1250 K, where the vitiated air follows at Mach 3, and this technique is based on a high accelerating effect of scramjet propulsion mechanism. Scramjet engines can maintain a naturalistic high enthalpy conditions in minimum durations. It is observed that the maximum temperature of 3510 K is attained at the recirculating zones that are produced because of undulation enlargement and therefore the fuel jet losses concentration whereas the maximum combustion efficiency of 86% is investigated from the current research work.

“…Due to the varying complexities associated with Lime mud, properties cannot be measured online. The samples of feed and fuel oil have to be sent to in house mill laboratory for detailed analysis and composition [33]. The amount of time spent on the same is significant and the delay associated with estimating the actual value would not help in correcting other dependent parameters such as fuel and air flows and excess oxygen concentration in air supplied.…”

Rotary lime kiln is an important pulp production facility of paper mills and cement factories. To achieve fully-automated lime kiln production, this paper firstly carries out a thorough review of the production processes of lime kiln, revealing that the shell temperature of lime kiln and furnace oil consumption are two key parameters to the working efficiency and product quality of the kiln. Next, an expert system was designed based on artificial neural network to optimize the parameters in kiln application. The functions and operations of the intelligent controllers in the system were also detailed. After that, the designed system was adopted to predict the shell temperature and furnace oil consumption using moisture in lime mud. The comparison between the predicted results and the real-time data of a plant shows that our system can predict the two key parameters accurately, enabling the operator to make sound decisions on many production indices. The research findings lay the basis for low-cost and high-quality lime kiln operations.
