Gas burner in low vacuum installation

A Vacuum system was designed and produced for the University of Groningen, where a gas flame could be studied by means of optical analytical techniques, such as Cavity Ring Down Spectroscopy and Laser Induced Fluorescence.

The pressure in the vacuum chamber can be neatly regulated between 1 and 100 mbar by using a throttling valve, which responds to the total pressure gauge. The experiments with Methane/Air mixture can reach temperatures of up to 2200° Kelvin, where water vapor is exposed. This vapor is being collected in a condenser, whereby the temperature of the gas will be reduced to 500° Kelvin, to protect the vacuum pumps. The challenge of designing this system was to find the right pumping capacity and to apply the right components, which could withstand the high temperatures.
