Good day everyone,

I have a question regarding the calculation of EOH of a gas turbine.
I was reading a report and there was a sentence saying : " the machine has 48.000 operating hours and 934 starts..... The unit has a total of 15.500 EOH." I do not understand how the EOH can be less than the operating hours.
I would expect that the equation would be somewhat like EOH = OH + ( f * starts) with f > 1. Am I wrong ?

With kind regards,
Marcus
 
I think the problem is the method of denoting thousands. In some European countries, a decimal point is used to denote thousands (rather than a comma, as here in the USA). If this system is used, then "15.500" is read as fifteen thousand, five hundred.

Best of luck!
 
EOH is usually equivalent baseload hours, so if your engine sees a lot of part-load operation then the EOH can drop down quite quickly causing the apparent discrepancy you're seeing.
