【摘要】 能否向喷雾干燥塔提供廉价的无污染高温干燥介质，是喷雾干燥技术中的难点和关键。我院采用以高温热管为主，同时配用部分中、低温热管作为传热元件制造而成的高温热管热风发生器，首先在喷雾干燥中应用成功，取得了满意的效果。更多还原

【Abstract】 It is a difficult and crucial problem in the spraying drying technologywhether cheap and non-pollutant high temperature drying material can be supplied tothe spraying tower or not.A high temperature hot-blast stove mainly made up ofliquid metal heat pipes with parts of naphthaline and carbon steel-water heat pipeshas achieved comolete success and satisfactory result first in the field of sprayingdrying. And it promises even wider applications in the future.更多还原
