Abstract

A heat exchanger is a device used to exchange heat and can usually function as a heater or a cooler. There are many types of heat exchangers available today. But the most widely used in industry is the shell and tube type heat exchanger. The shell and tube type heat exchanger has the advantages of being affordable, easy to maintain and has excellent heat transfer performance with a small volume. This paper aims to analyze the effect of mass flow rate on cold water inflow and hot water outlet temperature using water fluid in shell and tube heat exchanger. The design analysis that I did using the Solidworks 2019 software. This study only made a comparison by changing the mass flow velocity at the inflow of cold water with samples of 5 Kg/s, 10 Kg/s, 15 Kg/s, 20 Kg/s, 25 Kg/ s and 30 Kg/s and only sampled the hot water outlet temperature. The material used is stainless steel 321 on the shell and copper on the tube. The test results show that every increase of a multiple of 5 Kg/s there is a decrease in the average fluid temperature of 1.62 ℃ and the lowest temperature that can be achieved in this test is 52.33 ℃

Abstract

When discussing control systems for boilers, the PID (Proportional-Integral-Derivative) control algorithm is one of the most well-known and widely used. The PID control algorithm has been proven effective in controlling temperature and pressure within boiler systems. However, as technology advances, there have been advancements in more sophisticated and efficient control systems. One of these advancements is the utilization of adaptive control and model predictive control. Adaptive control can adapt to changes in operational conditions and provide better performance compared to PID control. Meanwhile, model predictive control utilizes a mathematical model of the system to predict future behavior and make control decisions based on these predictions. Nevertheless, the PID control algorithm remains crucial and can deliver satisfactory performance in temperature and pressure control within boilers. The key to effective use of PID control lies in the selection of appropriate parameters and proper tuning. By employing the correct tuning methods, PID control can achieve optimal performance and high efficiency in boiler systems. Overall, the use of the PID control algorithm remains a good choice for temperature and pressure control in boiler systems, despite advancements in more advanced and efficient control systems. Model predictive control, on the other hand, utilizes a mathematical model of the boiler system to predict its future behavior. By solving an optimization problem over a predictive horizon, it determines the optimal control actions to be applied. This proactive approach allows model predictive control to account for constraints, nonlinearity, and system dynamics, leading to improved control performance and energy efficiency. In conclusion, while PID control remains a viable option for temperature and pressure control in boiler systems, the advancements in adaptive control and model predictive control offer more sophisticated and efficient alternatives. The choice of control strategy depends on the specific requirements, complexity, and desired performance of the boiler system. Combining different control techniques or employing advanced control algorithms can further enhance the overall control performance and optimize the operation of the boiler system.

Abstract

Coconut is a type of plant from the Arecaceae and the sole member of the margos. This plant lives in tropical areas such as in Indonesia. West Kalimantan, which is one of the islands that has a large area, has the potential for the utilization of this coconut. This potential is utilized as in export needs, but due to the use of traditional technology, namely using a wedge in stripping coconut husk, there is often a delay in the export process, so technology such as a coconut husk peeler with electric power is needed which aims to obtain more stripping time. fast. The research method in the design is done by reading the literature, observation, experimental and descriptive by varying the blade with an angle of 0o and 5o in order to obtain maximum results. Coconuts whose husks are peeled using a coir peeler design with variations in angles have a peeling machine capacity of 333 pieces/hour and 383 pieces/hour. This result is greater when compared to using a wedge with an average stripping time of 180 pieces/hour, so it has a percentage of 0o of 185% and 5o of 212.78% higher, so it can help increase production and help in handling the export process.
