Abstract

Kinetic energy originating from liquid jets at high speed can be used as an energy source for liquid-gas ejector devices. An ejector is a tool often used to support one of the processes in the industry, such as vacuum process, desalination, distillation, and refrigeration. The ejector consists of several main components: the nozzle, suction chamber, mixing chamber or throat, and diffuser. These components influence each other, so that system performance is sensitive to the performance of these components. The diffuser functions as a dynamic head converter into a static head. Its performance is affected by its dimensions, so it needs to be investigated. This study aims to determine the effect profile of a diffuser with a divergence angle of 2β 7° and a diffuser with a tiered divergence angle of 2β. This study uses an experimental method with a motive flow pressure for the primary fluid of 201.32 kPa. This study found that changes in length and the angle of divergence of the diffuser affect the value of the pressure recovery coefficient and efficiency.

Abstract

This study aims to find out the effect of using a shroud mounted on an anila biomass gasification furnace. The casing functions as a guide and heats the air that will enter the combustion chamber. The method used in this study is an experimental method. The type of furnace used in the experiment is a biomass anila furnace. This furnace is made of metal. The casing is attached to the outside and envelops the furnace. Measurements made between long flame, starting time, and flame stability. The test results show that the average startup time is 10 minutes. long flame flame with cover is 87.79 minutes, while without cover is 72.28 minutes. The stability of the flame using the casing is more stable than without the casing.

Abstract

A liquid–gas ejector (LGE) is a vacuum-generating device that uses high-pressure liquid to entrain and compress gas and is widely applied in industrial processes. However, undesired recirculation within the suction chamber may reduce entrainment effectiveness and overall ejector performance. This study experimentally investigates the effect of a confined suction chamber on the performance of a  vertical downward flow. The modified chamber was designed to restrict the interaction zone between the liquid jet and the surrounding gas, thereby reducing circulation losses. The performance of the confined suction chamber was compared with that of a conventional suction chamber under the same operating conditions by evaluating suction pressure, static pressure distribution, flow ratio, and efficiency. The results show that the confined suction chamber produced lower throat pressure and altered pressure recovery along the throat and diffuser, indicating changes in the entrainment processes. It also delivered higher suction performance and greater maximum efficiency than the conventional configuration. The analysis indicates that, at a flow rate of 0.327 L/s, the confined suction chamber produces a lower absolute pressure of 44 kPa absolute than the conventional suction chamber, which records 54 kPa absolute. The highest efficiency obtained with the confined suction chamber was 9.94% at a flow ratio of 0.82, compared with 8.23% at 0.87 for the conventional chamber.
