Abstract

Coal is one type of fuel that can produce efficient combustion. One of the steam power plants that use coal as fuel to generate electricity is PLTU UBJOM Indramayu. In PLTU UBJOM Indramayu coal to be used as fuel has passed through several processes to form a coal powder ready to use for combustion. Initially the coal that is accommodated in the coal bunker will be smoothed by using a coal pulverizer where the amount of coal coming into the coal pulverizer is set in the coal feeder in control of the control room. At the time of this process of coal refinement, coal in the coal feeder will go to coal pulverizer inlet often experience plugging. The case of plugging here is when the wet coal conditions attached to the coal pulverizer inlet and accumulate so that the flow of coal to the coal pulverizer occurs interference. Due to a disruption, the fuel supply used for the burning process in the boiler will decrease which in the end the unit experiences derating. To handle plugging problems like this, it can be done with the addition of mounting sensors that can monitor pulverizer conditions. This sensor can detect the occurrence of coal deposits inside the coal pulverizer inlet and when the buildup occurs, the coal feeder must be closed immediately to accelerate the recovery of coal pulverizer.
