Get PDFSistem Kerja Soot Blower Menggunakan Limit Switch Pada Mesin Boiler Mb 13 Di Pt.Indah Kiat Pulp And Paper Perawang
No full textThe Soot Blower is a very important tool because it functions to clean the tubes in the boiler in the Heat Recovery Area (HRA), namely the Superheater, Economizer, Reheat area, as well as the Air Heater from adhering dirt/slag. Soot Blower sprays auxiliary hot steam to clean the outer walls of the tubes and heat exchanger elements in the Air Heater. The remaining combustion gas in the boiler combustion chamber is called flue gas. The flue gas resulting from combustion still contains a lot of ash. The liquid ash contained in the flue gas will stick and freeze when the flue gas reaches the convection heating area in the HRA. The deposition of liquid ash will be very hard, which is known as Bird Nesting. If the limit switch is not installed, the motor will rotate continuously and will cause the gears or beam to wear out, and the gear box gears. So the limit switch is very important as a supply breaker to the motor. The process of blowing or spraying steam against the soot, in this process the power supply becomes the ON position and will supply electricity to the limit switch and electric motor. The electric motor will move mechanically to rotate the gear box and lance tube which are connected by a chain. And the function of the limit switch is only to cut off the supply to the motor, when the motor is in the spraying position. After the motor has pressed the limit switch, the motor will be in the OFF position because it has pressed the limit switch which is the supply breaker to the motor
Rancang Bangun ATM Beras Menggunakan RFID Card
Get PDFThe distribution of Raskin in villages currently still uses manual methods so that it often faces obstacles, such as fraud in weighing rice and also the process of distributing rice which takes time. The aim of this research is to create a rice ATM machine that can control rice output efficiently. The tool works when the registered ID card is scanned on the RFID, the servo motor will open the rice channel. The rice that comes out is weighed on the load cell sensor. If the rice weight reaches 1 kg, the servo motor closes the rice output. Based on the results of the tests carried out, the average error rate on the tool was 12.13% with a tool success rate of 100 %
