    In fire-tube boilers, the flue gas passes inside boiler tubes, and heat is transferred to water on the shell side. A dynamic model has been developed for the analysis of boiler performance, and Matlab has been applied for integrating it. The mathematical model developed is based on the first principles of mass, energy and momentum conservations.Learn More

  • High pressure boiler design — Heating Help: The Wall

    I know the pressure gauge on the locomotives went a little over twice the release pressure of the safety valves on the locomotives. I am pretty sure they operated their locomotives at 125 psi or a bit more. These were fire-tube boilers, but I do not think any had super-heaters. From time-to-time they had to replace the fire tubes and boiler stays.Learn More
