Combustion analyzer with simultaneous carbon monoxide and methane measurements

A combustion analyzer configured to simultaneously detect the concentrations of oxygen, carbon monoxide and methane in a combustion process is provided. The combustion analyzer includes an oxygen sensor configured to detect the oxygen in the combustion process and generate a sensor signal indicative of the concentration of oxygen in the combustion process. The combustion analyzer further includesa dual carbon monoxide-methane sensor configured to operate at approximately 400 DEG C and provide a second sensor signal indicative of methane concentration and at approximately 300 DEG C. to selectively provide a third sensor signal indicative of carbon monoxide concentration. The combustion analyzer finally includes a controller configured to receive the sensor signals, determine the concentration of oxygen, and generate a carbon monoxide concentration output and methane concentration output based on the dual carbon monoxide-methane sensor signals and the concentration of oxygen. 提供了一种燃烧分析仪，其被配置为同时检测燃烧过程中氧气、一氧化碳和甲烷
