Estimating the Steam Generator Performance By using the Heat-Loss Method
Abstract
A mathematical model has been developed and realized in computer code for the thermodynamic analysis of steam-generating units. This mathematical model involves a computational procedure that uses the heat-loss method to estimate the efficiency of steam-generating units operating on either liquid or gaseous fuels, such as fuel oil or natural gas, respectively. This procedure is based on the ASME Power Test Code that is recommended internationally for evaluating the performance test procedure for steam generating units. The mathematical model results were compared with those obtained from the experimental performance tests carried out on AL-Dura and AL-Mussaib power station steam generating units. A good agreement was achieved from this comparison. It was found that burning natural gas in boilers is preferred due to the low rate of pollutant emission. In addition, large-capacity boiler units are more efficient when operated at partial capacity as compared with smaller boilers.
