NONSTANDARD APPROACHES DEVELOPMENT OF AN EFFECTIVE CRYOGENIC PRODUCTS ATMOSPHERIC EVAPORATOR

Abstract

The consumers cryogenic and heat exchange equipment make high demands to products including the atmospheric evaporators of cryogenic liquids. At present with interest relate to design of the device having a relatively low cost, providing a longer period of continuous operation and with a reasonable amount weight and size characteristics. When choosing a device as an advantage is considered its ability to work on vehicles often. The achievement device high values of listed parameters prevent the precipitation in the form of snow and ice that are formed due to condensation and crystallization of water from the atmospheric air. In order to eliminate their negative influence in some cases resort for increased heat exchange surface of the devicethat leads to increasing its size and weight. Describes nonstandard approaches to developing an effective atmospheric evaporator for liquid cryogenic products. Summarizes the characteristics of the developed evaporator at a rate of 240 Nm3/ h of oxygen at a pressure of 400 bar. Comparison with existing devices indicates its advantages.
