Abstract:
An instrument has been developed to monitor the
equivalence ratio in combustion systems. It is based on
a novel oxygen consumption measuring method. The
instrument does not require knowledge of the chemical
composition of the process being monitored. Both
gaseous and solid (soot) products of incomplete
combustion are successfully handled. The device is
relatively compact and can be developed for moderate
cost and portable use.
