Air Fuel Ratio Effect on Combustion Efficiency - Sage …

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.

ratio control and metered-air combustion processes

Ratio Control and Metered-Air Combustion Processes

By Allen Houtz 1 and Doug Cooper. A ratio control strategy can play a fundamental role in the safe and profitable operation of fired heaters, boilers, furnaces and similar fuel burning processes. This is because the air-to-fuel ratio in the combustion zone of these processes directly impacts fuel combustion efficiency and environmental emissions.
