Abstract: A 5 kW steam generator that has failed was refurbished by redesigning, replacing and reassembling of some critical components. The aim was to enhance the new steam generator performance by increasing the maximum steam temperature and pressure while reducing fuel consumption rate. The failed parts were identified, and standard design equations were used to redesign the critical components – including the riser, downcomer, superheater and the steam drum. Additionally, the steam gauge and pressure gauge were replaced. After the reassembled, the new steam generator was tested to determine its performance. From the experimental test, the result showed that the maximum steam temperature, maximum steam pressure dryness fraction, and fuel consumption rate were 235 °C, 0.39 MPa, 0.95 and 2.92 kg/hr respectively, for one hour of running. These outcomes represent an improvement (%) compare to the previous studies.
