Project Summary:<br />
Fuel testing and controlling its quality is important in operation of power plants. At<br />
present in most of the country's power plants, natural gas is used as main fuel and heavy<br />
fuel or gas oil as alternative one. The efficiency of power plants is affected by various<br />
factors including fuel heat value and composition. Moreover, the chemical composition<br />
of the fuels around the country is not identical and depends on gas providing source.<br />
Therefore in order to study the fuel quality effect on power plant performance, it is<br />
necessary to test fuels in various periods of the year. In this project 21 power plant unit<br />
was selected in such a manner that the effects of various climatic condition and units<br />
lifetimes could be studied. Then fuel sampling and testing were performed during five<br />
periods of a year. Also the operational data of each unit was gathered. Then the unit<br />
efficiencies during fuel sampling periods were calculated and their variations were<br />
plotted. In the next step, the testing results and operational data were analyzed and the<br />
effect of various factors such as fuel chemical composition, operational parameters,<br />
power plant lifetime and locations,. on plants efficiencies were determined. At final<br />
step, the efficiencies of power plants were compared and recommendations for their<br />
improvements were offered.<br />
Project results:<br />
• Study of the power plants in the different seasons of the year and comparing<br />
them from the efficiency and fuel specification point of views<br />
• Determining the priority of the power plants for installation of online fuel<br />
sampling and chemical analysis system.<br />
• Preparing proposal for using weight and colorific counters instead of current<br />
volume counters in power plants in short-term and long-term planning<br />
respectively<br />
• Preparing proposal for periodic sampling and chemical analysis of fuel in power<br />
plants<br />
• Offering recommendations regarding improvement of gas fuel heaters, using<br />
duct burner in gas turbines, modification of gas pipe line, proper using of gas<br />
units in power generation, ….<br />
