Abstract:
Since the order of various components of coal fired product are different from each other to a great extent, the convergent speed by using the steepest descent and Newton’s method directly will be very slow. It is a computer time consuming job and divergent if the initial values of product composition is not rationally selected. For solving this problem, this paper improves the selection of variables aand objective function. It enhances the convergent speed and calculation accuracy obviously and decreases the iteration from about hundred times to less than ten times, which shortens the computer time consumption to a great extent. In addition, the initial value selection with accuracy is no more required.
