Method and apparatus for real time measurement of particulate matter in combustion gases |
摘要 |
A method and apparatus for measuring particulates in a combustion gas is accomplished by dividing the combustion gas into a first and second sample gas. The first sample gas is filtered to remove particulates to create a reference gas sample. A combustion furnace can heat both the reference gas sample and the sample gas to oxidize any particulates in the sample gas. A gas analyzer that is connected to the furnace can detect the gas components in, respectively, the reference gas sample and the sample gas, and a comparison of the detected results can determine the concentration of particulates.
