Superheated Vapor - an overview | ScienceDirect Topics
Superheated vapor is solvent vapor heated to and beyond its normal boiling point at atmospheric pressure. Its unique capability is to heat materials to above the normal boiling point of the solvent used. • The prime use of superheated vapor is to vaporize the last traces of liquid solvent retained within part crevices. It’s about drying!
The heat and mass transfer characteristics of superheated steam …
2017年11月8日 · The study on the flow characteristics of superheated fluid in wellbores is still at the early stage. In recent years, Zhou et al. [35] , Xu et al., [36] , [37] , Fan et al. [38] and Sun et al. [3] , [39] , [40] presented numerical models focusing on the flow behaviours of single-phase superheated steam in onshore or offshore single-tubing ...
Superheated Gas - an overview | ScienceDirect Topics
Figure 18.1 depicts qualitatively the state point of oxygen at ambient conditions and shows that it is a superheated gas at this pressure and temperature, existing at well above the critical temperature, but below the critical pressure.
Superheated steam drying - ScienceDirect
2023年1月1日 · Superheated steam drying (SSD) is simply a kind of convective drying of materials by utilizing steam-heated beyond its boiling point instead of air, which is in direct contact with the material. This chapter discusses the fundamentals of SSD, different methods of SSD application, and mathematical models developed for SSD applications.
Superheated steam drying: Design aspects, energetic …
2016年7月1日 · A superheated steam vacuum drying trial was developed by Pang et al. [36], [37], [38] in order to dry a stack of wood, as illustrated in Fig. 13 (rearranged from Ref. [37]). The steam is heated to the wanted dry-bulb temperature by hot oil which can flow using a pump through heating coils above the stack of wood.
Superheated steam drying: Design aspects, energetic …
2016年7月1日 · A superheated steam fixed bed dryer was designed and fabricated by Zielinska et al. [72]. The design of the dryer is illustrated in Fig. 11 (rearranged from Ref. [72] ). Before entering into the drying chamber, the steam, generated by a steam generator, is heated to superheated steam using a 4 kW heater.
Superheated Liquid - an overview | ScienceDirect Topics
Superheated liquids are those that have been heated to a temperature far exceeding their boiling point. When methanol is being considered for use in the production of biodiesel, it has to be heated to temperatures (nearing 250 °C) that well exceed its normal boiling point (64 °C) under a pressure of 0.1 MPa.
Superheated fuel sprays: A comparative study of flash boiling …
2024年9月1日 · The experimental results indicated that ammonia spray behavior significantly differed from other tested fuels for both under cold and superheated conditions. The effect of superheating on methanol, ethanol, and gasoline sprays was very similar, resulting in the shrinkage of spray width and the merging of adjacent plumes into a single thick ...
