Webor lean (excess air). Either way, it wastes fuel. Because there is not enough air for complete combustion, oper-ating the burners at rich combustion conditions wastes fuel by allowing it to be discarded with some of its energy unused. It also generates large amounts of carbon monoxide (CO) and unburned hydrocarbons (UHCs). WebVandaag · The MarketWatch News Department was not involved in the creation of this content.
