Abstract

Salah satu proses dalam produksi RDF adalah proses pengeringan. Pada tahap pengeringan, produk RDF akan di-treatment di dalam kiln dryer untuk menurunkan kadar moisture hingga mencapai kriteria yang diinginkan. Pada dry and inceneration system, terjadi proses pembakaran RDF untuk menghasilkan gas panas yang selanjutnya dialirkan melalui ducting menuju ke inlet kiln dryer untuk pengeringan produk RDF dan selanjutnya akan gas akan di-treatment melalui flue gas treatment system agar dapat mengurangi emisi gas saat dilepaskan ke atmosfer melalui cerobong asap (stack). Fluktuasi tekanan di dalam furnace akan terus berlangsung pada saat terjadi pembakaran di dalam furnace. Hal tersebut dapat mempengaruhi efisiensi prmbakaran dan memicu potensi terjadinya mechanical stress pada dinding furnace yang dapat mengurangi masa pakai. Selain itu, fluktuasi pada tekanan di dalam furnace akan mengakibatkan pembakaran tidak sempurna dan juga aliran gas yang akan mengalir melalui jalur aliran yang semestinya sehingga dapat mengakibatkan kondisi yang berbahaya bagi pekerja di lapangan dan juga pada peralatan di sekitarnya. Steady state tekanan di dalam furnace pada dapat dicapai dengan adanya penerapan algoritma kontrol, salah satunya merupakan kontrol PID. Berdasarkan hasil perancangan kontroller dengan menggunakan Ziegler-Nichols Second Method Rules dan trial and error diperoleh hasil yang terbaik dengan overshoot = 0%, error steady state = 0 dan settling time =70 detik dengan parameter Kp = 1.0, Ti = 5 detik, Td = 1.01 detik.

One of the processes in RDF production is the drying process. In the drying stage, the RDF product will be treated in the kiln dryer to reduce the moisture content until it reaches the desired criteria. In the dry and incineration system, the RDF combustion process occurs to produce hot gas which is then channeled through the ducting to the inlet kiln dryer to dry the RDF product and then the flue gas will be treated through a flue gas treatment system in order to reduce gas emissions when released into the atmosphere through chimney (stack). Pressure fluctuations in the furnace will continue when combustion occurs in the furnace. This can affect combustion efficiency and trigger the potential for mechanical stress on the furnace walls which can reduce equipment lifetime. In addition, pressure fluctuations in the furnace will result in incomplete combustion and also gas flow which will flow through the proper flow path, which can result in hazardous conditions for workers in the field and also for the equipment. Steady state pressure in the furnace can be achieved by applying control algorithms, one of which is PID control. Based on the results of the controller design using the Ziegler-Nichols Second Method Rules and trial and error, the best results are obtained with overshoot = 0%, steady state error = 0 and settling time = 70 seconds with parameters Kp = 1.0, Ti = 5 s, Td = 1.01 s.
