SUMMARY

Constructing a rig to control a Bunsen flame within a pressure vessel is feasible by utilizing a pressure transmitter to modulate the flame's energy based on vessel pressure. The Bunsen burner operates on the principle of differential pressure between gas and ambient air, allowing combustion at various pressures, provided the correct pressure difference is maintained. Additionally, ensuring a continuous airflow into the pressure vessel is crucial to prevent oxygen depletion, which is essential for sustaining the flame.

PREREQUISITES
  • Understanding of pressure transmitters and their applications
  • Knowledge of combustion principles and gas-air mixing
  • Familiarity with control loop systems for energy modulation
  • Basic principles of fluid dynamics related to airflow
NEXT STEPS
  • Research the design and implementation of pressure control systems for combustion applications
  • Explore the principles of differential pressure in gas mixing for combustion
  • Learn about continuous airflow systems and their importance in combustion safety
  • Investigate control loop design techniques for modulating flame energy
USEFUL FOR

Engineers, researchers, and technicians involved in combustion systems, pressure vessel design, and control systems will benefit from this discussion.

Is it viable to construct a rig in which the pressure of the vessel can be controlled whilst a Bunsen flame is kept burning inside of it?

In principle you could use a pressure transmitter and vessel pressure as the proportional signal for modulating the energy of the flame in a control loop.
 
A Bunsen uses the differential pressure of the gas and the ambient air to mix the gases before combustion. That should work at any reasonable pressure, so long as you have the correct pressure difference. That means you will have to control the gas pressure as well as the air pressure.

Of course you will need a continuous air flow through your pressure vessel, otherwise you will soon run out of oxygen!
