ABSTRACT

FD FAN (forced draft fan) is a device used to pressurize gas or air and transfer it to a desired location, and a vane damper is used to control the suction flow rate. The vane damper is a flow rate control valve that controls the suction flow rate of air by adjusting the opening and closing angle of the vane for complete combustion inside the ship boiler. Most ships have fans that can automatically or manually adjust the flow rate using a link-type vane damper. However, due to the imbalance of the link that controls the angle of the vane at the initial 0-20 degree angle, the vane is suddenly opened in a short moment, and a large amount of flow is instantly introduced into the boiler, resulting in serious soot generation due to incomplete combustion. This is because there are structural problems in the assembly imbalance due to the complex structure of the link controlling the vane damper, the transmission torque applied to the link shaft is not evenly distributed, and the technical problems that cause the shaft to be destroyed due to the phenomenon of being concentrated on a specific link. In this study, in order to develop a gear type vane damper that replaced the link type, the torque generated was analyzed to minimize the amount of backlash and the quality and productivity according to the assembly type were improved. The strength of the bevel gear was proved, and environmental tests for basic IoT research were evaluated in consideration of the specificity of the ship.
