Abstract
A novel Flame Temperature Analyzer (FTA) method and apparatus for measuring combustible gas concentration and oxygen content in a sample gas includes supplying a mixture of oxidant and fuel to a sensing flame and measuring the temperature of the flame as the sample is added to the combustion chamber.
Claims18
A gas analyzing method, comprising:
- a) filling a flame cell with a sample gas;
- b) burning a mixture within said flame cell, said mixture including a fuel and an oxidant present in proportions such that said burning creates a diffusion flame including an inner ignition zone and a main reaction zone;
- c) measuring a temperature of said diffusion flame;
- and
- d) calculating a concentration of combustible gases contained in said sample of gas using said temperature.
2 more elements
A gas analyzing apparatus, comprising:
- a flame cell;
- filling means for filling said flame cell with a gas sample;
- providing a flammable mixture, said mixture including a fuel and an oxidant;
- burning means for burning said mixture inside said flame cell, thereby creating a diffusion flame including a main reaction zone and an inner ignition zone;
- measuring means for measuring a temperature of said diffusion flame;
- and
- combustible gas concentration calculating means using said temperature for determining a concentration of combustible gases in said gas sample.
4 more elements
A gas analyzing device, comprising:
- a flame cell filled with a gas sample;
- a burner tube having a first and a second end, said first end being located inside said gas filled flame cell, and said burner tube being supplied via said second end with a mixture including a fuel and an oxidant;
- a diffusion flame created inside said flame cell by burning said mixture at said first end of said burner;
- said diffusion flame having a main reaction zone and an inner ignition zone;
- a temperature sensor located near said diffusion flame capable of providing a temperature of said diffusion flame,
- a calculator capable of using said temperature to determine a concentration of combustible gases contained in said sample.
