FLUE-GAS ANALYSIS SAFETY APPARATUS

摘要

Flue-gas analysis safety apparatus (10) for a gas or oil-fired device (30) having an electrical connection and a flue (54) for combustion gases, comprises a hazardous gas detection element (12) for placement in the flue (54) to monitor flue gas, and a controller (14) for automatically regulating a gas to air ratio in the flue gas based on a signal from the hazardous gas detection element (12). The controller (14) is able to halt a flow of electricity to the gas or oil-fired device (30) if the gas to air ratio in the flue gas cannot be regulated to fall within a predetermined safe parameter. Preferably, the hazardous gas detection element (12) includes a wireless transmitter, and the controller (14) includes a wireless receiver so that the hazardous gas detection element (12) is wirelessly communicable with the controller (14). A gas or oil-fired device having the apparatus (10), and a method are also provided.
