Discussion Overview

The discussion centers on methods to generate steam at a pressure of 2 bar and a temperature of 403 K, with a specific mass flow rate requirement of 0.0123 kg/s. The focus is on finding economical solutions suitable for a project work context.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant suggests using a positive displacement pump to push cold water through a heated tube to generate steam without the need for storage, which could enhance safety.
  • The proposed method involves maintaining the tube at 403 K using an electrically heated oven controlled by a thermostat.
  • Another participant inquires about the type of oven suitable for this application and whether ready-made options are available in the market.
  • A later reply notes that a positive displacement pump would also increase the pressure of the water.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the specific type of oven to use or the details of the implementation, indicating that multiple approaches and considerations are still under discussion.

Contextual Notes

There are unresolved questions regarding the specifications and availability of suitable ovens, as well as the exact operational parameters for the proposed steam generation method.

I am in a need to generate steam of 2 bar pressure, 403 K temperature and a mass flow rate of 0.0123 kg/s. Its just needed for my project work. Kindly suggest some ways to generate it economically. Thanks in advance.

Since you require a constant flow of 12.3 g/sec you should be able to do that without storage of steam under pressure. That will make it significantly safer.

Use a positive displacement pump to push 12.3 cc of cold water per second, up a heated tube through an oven. The oven maintains the tube at 403 K. It could be heated electrically and controlled by a thermostat. The pressure will be set by the rate you release the steam.
 
Thanks for your kind replay. What kind of oven I can use for it? For this purpose whether I could get any ready made oven from market? If so, kindly give me the information about it.
Thanks in advance.
 
Pd pump would also increase pressure of water...
