Abstract

Pada PLTU berbahan bakar batu bara, penumpukan slag dan fouling pada dinding boiler dapat menurunkan efisiensi perpindahan panas serta meningkatkan konsumsi bahan bakar. Metode pembersihan yang umum digunakan adalah soot blower, namun metode ini memiliki keterbatasan karena pembersihan bersifat lokal, membutuhkan energi besar, dan berpotensi menyebabkan erosi pada pipa boiler. Sebagai alternatif, Rancangan Sistem Detonation Wave dikembangkan sebagai sistem pembersihan berbasis gelombang tekanan dari proses deflagrasi terkontrol campuran gas propana dan udara bertekanan. Tugas akhir ini merancang sistem kontrol otomatis menggunakan Programmable Logic Controller dan Human Machine Interface dengan metode cascade. Sistem dirancang untuk mengatur urutan kerja mulai dari standby, piston menutup, pengisian bahan bakar, pengisian udara, ignition, piston terbuka, pembersihan,hingga memulai siklus dari awal. Sistem juga dilengkapi perhitungan set point bahan bakar dan udara, scaling pressure sensor, serta interlock dan fault sebagai proteksi keselamatan. Hasil perancangan dan simulasi menunjukkan bahwa sistem kontrol dapat menjalankan siklus operasi rancangan sistem detonation wave secara otomatis, berurutan, dan aman. Integrasi PLC dan HMI berhasil dilakukan sehingga status proses, tekanan, dan kondisi sistem dapat dipantau secara real-time. Dengan demikian, rancangan ini dapat menjadi dasar pengembangan sistem otomasi sistem detonation wave sebagai alternatif metode pembersihan slag pada boiler PLTU.

In coal-fired power plants, the buildup of slag and fouling on boiler walls can reduce heat transfer efficiency and increase fuel consumption. A commonly used cleaning method is the soot blower; however, this method has limitations because cleaning is localized, requires a large amount of energy, and has the potential to cause erosion in boiler tubes. As an alternative, the Detonation Wave System was developed as a cleaning system based on pressure waves generated by the controlled deflagration of a mixture of propane gas and pressurized air. This thesis designs an automatic control system using a Programmable Logic Controller (PLC) and a Control (HMI) with a cascade method. The system was designed to manage the sequence of operations, ranging from standby, piston close, fuel filling, air filling, ignition, piston open, flushing, to restart delay. The system also includes calculations for fuel and air set points, pressure sensor scaling, as well as interlocks and fault detection mechanisms for safety protection. The design and simulation results show that the control system can execute the operational cycle of the detonation wave system automatically, sequentially, and safely. The integration of the PLC and HMI was successfully carried out, allowing the process status, pressure, and system conditions to be monitored in real time. Thus, this design can serve as the basis for developing an automation system for the detonation wave system as an alternative method for slag removal in coal-fired power plant boilers.
