Non-Dispersive Infra-Red sensor for CO2 monitoring in the flue gas

Carbon dioxide as a colorless, odorless gas is emitted both naturally in the environment, and unnaturaly through human actions related to the burning of fossil fuels such as coal, natural gas and oil (including gasoil and heavy oil). According to EPA report, this gas is the main greenhouse gas emitted by human activities. The identities of the target gases are already known for the majority of infra-red gas sensing applications. So there is little need for gas spectrometry. The user must still measure the concentration of the target gas, but may be able to accept a certain degree of cross-sensitivity between different gases (especially in the flue gas), if their absorption lines overlap. Therefore, A Non-Dispersive Infrared sensing technique (as a novel molecular absorption spectroscopy technique) has been developed. In this paper, Non-Dispersive Infra-Red sensor for CO2 monitoring in the flue gas is represented.
