Method and apparatus for reducing ozone

摘要

In the decomposition of ozone in aircraft, the ozone level in an airflow upstream of the aircraft cabin is measured and a signal generated in accordance with the sensed level. This signal is amplified to a given value and a valve is opened or closed in response thereto. Connected to the valve is a source of nitric oxide under pressure. When the valve is opened a measured quantity of nitric oxide is dispensed to a location in said airflow remote from said ozone monitoring device.
