Flame module

A gas supply system for a flame module of a spectrometer and a method of controlling a flame module. The gas supply system comprises an oxidant gas supply line for providing a supply of oxidant gas, an oxidant gas flow valve for varying a gas flow rate of an oxidant gas in the oxidant gas supply lin...

Summary:A gas supply system for a flame module of a spectrometer and a method of controlling a flame module. The gas supply system comprises an oxidant gas supply line for providing a supply of oxidant gas, an oxidant gas flow valve for varying a gas flow rate of an oxidant gas in the oxidant gas supply line, an oxidant gas safety controller configured to control the oxidant gas flow valve, a fuel gas supply line for providing a supply of fuel gas, a fuel gas flow valve configured to control a gas flow rate of a fuel gas on the fuel gas supply line, and a fuel gas safety controller configured to control the fuel gas flow valve. During normal operation, the oxidant gas safety controller is configured to charge an energy storage circuit of the oxidant gas safety controller. In the event of a power failure, a first switch of the oxidant gas safety controller is configured to connect the energy storage circuit to the oxidant gas flow valve, wherein the energy storage circuit is configured to discharge energy to the oxidant gas flow valve to increase the oxidant gas flow rate in order to extinguish a flame of the flame module, and the fuel gas safety controller is configured to close the fuel gas flow valve.
