蒸気発生装置

Steam generator

Abstract

<P>PROBLEM TO BE SOLVED: To provide a steam generator for continuously generating steam while maintaining well-balanced thermal energy supply between a heat carrier part and an evaporation part. <P>SOLUTION: The steam generator is provided with a heat source body 11 in which a heat source 10 is buried, a carrier pipe heating part 13 for boiling liquid in a carrier pipe 12, and a heat transfer control part 14 formed of a material having smaller heat conductivity than a material for the evaporation part 31. While the heat source is set at a higher temperature to secure thermal energy to be supplied to the side of evaporation, the transfer amount of heat to the carrier pipe 12 is reduced to suppress the deposition of scales accompanying local boiling in the carrier pipe. <P>COPYRIGHT: (C)2005,JPO&NCIPI
【課題】本発明は、熱搬送部側と蒸発部側との熱エネルギ供給バランスを良好に保ち、連続的に蒸気を発生する蒸気発生装置を提供する。 【解決手段】熱源10を埋め込んだ熱源本体11、搬送管12内の液体を沸騰させるための搬送管加熱部13、蒸発部31を形成する材料より熱伝導率が小さい材料からなる伝熱制御部14を備え、熱源を高い温度に設定して蒸発させる側に供給する熱エネルギを確保しつつ搬送管12への伝熱量を低減して搬送管内の局部沸騰に伴うスケール付着を抑制できる。 【選択図】 図1
