） Abstract： This paper focuses on the optimal pitch arrangement in double-side heating once-through steam generator with helix tube inside
According to the experimental results in literature, it was analyzed that the effects of the pitch on frictional pressure drop and heat transfer coefficient in boiling section
And the pitch was optimized by the constrained nonlinear optimization method
The result showed that the optimal pitch can be fitted well by exponential function in boiling section
And the conclusions can be used for engineering practice
