Abstract (en)

[origin: US5165883A] PCT No. PCT/DE89/00692 Sec. 371 Date Jul. 16, 1991 Sec. 102(e) Date Jul. 16, 1991 PCT Filed Oct. 26, 1989 PCT Pub. No. WO91/06808 PCT Pub. Date May 16, 1991.A process and apparatus for monitoring and ensuring safe operation of unvented kerosene heaters in indoor spaces detects the hazard of incomplete combustion and the concomitant reduced O2 and increased CO2 levels in the indoor air. CO2 level in the indoor air is monitored quickly and accurately, - regardless of the burner's flame height. This is achieved by sensing O2 level in the burner exhaust which is used as a measure for monitoring the CO2 level in the indoor air and as a control signal. During burner operation outside a predetermined flame height range, the O2 detection is used both for restoring a normal heating condition and for monitoring operation at minimum flame height and to generate a warning signal and a delayed automatic shut-down of the burner.
