Burnermax

Function

The BurnerMax measures and controls the oxygen content of flue gases from combustion processes. If too much air is supplied to a combustion plant, then the flue gas volume increases unnecessarily and too much latent heat is released with the flue gases to the atmosphere. Therefore energy and hence fuel is wasted.

If not enough air is supplied to the combustion process, the combustion becomes incomplete with the result of emission of smoke and unburned hydrocarbons. This leads to air pollution and environmental problems and again the efficiency of the combustion process is reduced and fuel cost increases.

Ambient air pressure and temperature, fuel properties and conditions of the combustion plant and auxiliary equipment all influence the air to fuel ratio uncontrolled. The optimum air to fuel ratio can therefore only be maintained with continuous control of this ratio.

Without controlling the oxygen content the flue gas fluctuates (red graph), even falling to 0% is possible (smoke emission).

With control the flue gas oxygen remains constant low (red graph), about 2% in this case. The heat loss is minimised, incomplete combustion with smoke development is prevented.
