- 摘要：
- A method and apparatus for monitoring the concentration of a component of a gas stream. The gas stream to be monitored is heated to a desired temperature and passed through an insulated gas passageway of a conduit member. The heated gas passes sequentially through a perforate metal shield and a body of a particulate catalyst. The temperature of the heated gas entering and leaving the conduit member is monitored and any increase in temperature is correlatable with the component concentration in the gas stream. The method and apparatus are particularly suitable for monitoring the concentration of hydrogen or oxygen in a gas stream.
