一种无高压蒸汽加热结构

Abstract

本实用新型提供了一种无高压蒸汽加热结构，包括有蒸汽发生腔、进水管、上气道引流室、下气道引流室、蒸汽引出装置和加热装置；所述进水管连接于蒸汽发生腔的侧部；所述下气道引流室的容积小于上气道引流室的容积；所述蒸汽引出装置的下端位于下气道引流室的底部，其上端穿出蒸汽发生腔；所述蒸汽气道引流单元设置于所述蒸汽发生腔内，用于将上气道引流室腔内的蒸汽引流至下气道引流室内。本实用新型在蒸汽发生腔内注水加热产生蒸汽，然后通过蒸汽气道引流单元将上气道引流室内的蒸汽导向下气道引流室，在导流过程中，蒸汽体积被压缩，压力升高、温度升高，最后从下气道引流室的底部经蒸汽引出装置排出，实现了无高压状态下的高温蒸汽发生供给。
