Air Fuel Ratio Effect on Combustion Efficiency

In small appliances, like in gas fired local room heaters there is no air/fuel ratio control. The air/fuel rate is factory-adjusted to be the best possible at the maximum power of these appliances by the manufacturers. These appliances have natural draught combustion chambers, without fan to assist in the flow in the combustion chamber.
