Abstract (en)

[origin: US4698015A] An installation for monitoring combustion to control pollution and retard other deleterious effects of improper combustion employs a smoke sampling duct to draw off a portion of the smoke emanation from the combustion chamber. The smoke in the sampling duct flows past a probe and is then vented from the duct. The probe senses oxygen or other substances in the smoke and emits signals to a device which analyzes the quality of combustion. A gas inlet in the sampling duct is situated upstream of the probe and gas is intermittently discharged into that duct to ascertain whether the probe is operating properly.
