ABSTRACT:
An artificial gas log set which simulates in a very realistic fashion a log fire in a fireplace. The artificial log set comprises a log, a burner tube having ports for creating a yellow flame that is in close proximity to the log and a second set of ports for creating a blue flame which is positioned between the yellow flame and the log. The blue flame impinges on the log and acts as a separator or curtain that prevents impingement by the yellow flame on the log. This prevents the creation of unwanted and dangerous levels of emissions such as oxides of carbon and nitrogen. An alternative embodiment replaces the blue flame and its ports with duct work and exhaust gases. The exhaust gases act as a separator between the log and the yellow flame. The result is a realistic looking, simulated wood burning fireplace which may be safely used in an unvented environment.
