SUMMARY

To generate steam at 2 bar pressure and 403 K with a mass flow rate of 0.0123 kg/s, a positive displacement pump is recommended to push cold water through a heated tube. The tube should be maintained at 403 K using an electrically heated oven controlled by a thermostat. This method eliminates the need for steam storage, enhancing safety and efficiency. The pressure can be regulated by controlling the steam release rate.

PREREQUISITES
  • Understanding of positive displacement pumps
  • Knowledge of thermal dynamics and steam generation
  • Familiarity with temperature control systems, specifically thermostats
  • Basic principles of fluid mechanics
NEXT STEPS
  • Research suitable positive displacement pumps for steam generation
  • Explore options for electrically heated ovens that maintain 403 K
  • Learn about steam pressure regulation techniques
  • Investigate safety protocols for operating steam generation systems
USEFUL FOR

Engineers, project managers, and researchers involved in thermal systems, steam generation, or those seeking efficient methods for generating steam for industrial applications.

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...
