ABSTRACT
The information gathered together in previous chapters provides guidelines for the construction of a burner that is correctly sized (physically and thermally) for a particular application and gives a flame that is stable with respect to lift and lightback. An important aspect not yet covered is that of burner controls, which may be fitted to an appliance in order to optimize efficiency, safety and ease of operation. A wide variety of such controls is available both for industrial and for domestic equipment. For example, devices are available that can regulate pressures and flow rates of gas and air and ensure effective and safe ignition of the gas stream. Controls that maintain combustion quality over a range of operating conditions are used in industrial applications but have yet to be proven in domestic appliances.
