Abstract
Biomass gasification is the process of partially oxidizing organic matter into hydrogen, carbon monoxide, and other gases that can be combusted in engines to generate electricity. The process emits nitrogen oxides (NOx gases) whose concentrations must be accurately measured. This project evaluated the accuracy of the portable Continental Smart NOx Sensor by comparing its readings to those of an external laboratory grade analyzer. The Continental sensor consistently read higher NOx concentrations than the analyzer, though it is unclear whether the sensor simply measured inaccurately or was affected by ammonia in the exhaust, as is known to be a potential issue with onboard NOx sensors. Because the ammonia content of the exhaust was not checked, the Continental sensor’s accuracy was ultimately not determined and more research is required.
