This paper focuses on the optimal pitch arrangement in double-side heating once-through steam generator with helix tube inside. 本文主要研究了帶內(nèi)螺旋纏繞管的管套管雙面加熱直流蒸汽發(fā)生器元件中沸騰段內(nèi)螺旋管螺距設(shè)置的優(yōu)化問題。
The once-through steam generator with double-side heat transfer component was presented in this paper. And the component is composed of straight tube outside and helix tube inside. 介紹了一種雙面換熱的套管式直流蒸汽發(fā)生器，其元件由直管外管和螺旋內(nèi)管組成。 www.aest.org.cn
In the first place, a formula is proved for indicating a magnetic induction strength inside a long straight helix tube carrying current, with the tubes cross section in tetragonal N regular polygon. 首先證明了正N邊形截面長直螺線管內(nèi)部磁感應(yīng)強度的公式，進而證明了長直螺線管內(nèi)部磁感應(yīng)強度與橫截面的形狀無關(guān)。
