Combustion Management Systems

To ensure maximum efficiency in the operation of any boiler, two requirements are of paramount importance.

The first being that the air to fuel ratio is kept to the minimum to ensure complete combustion within the limitations of the combustion head design and that these settings, once arrived at, are infinitely repeatable to an incredibly high degree of accuracy.

The second requirement should be that the target temperature or pressure of the boiler is monitored by the combustion system, and that at all times exactly the right amount of fuel and air is fired to achieve the target value.

The inherent hysteresis of all mechanical systems that have traditionally involved cams and linkages to characterize the fuel/air ratio have made this sort of accuracy impossible. The accuracy of response of fuel input to the monitored target temperature/pressure of the boiler has meant that the target set by the operator has at most times been exceeded or fallen short of. Autoflame Engineering were the first in the World to develop a system that overcomes all these problems by utilizing the latest micro processor technology.

The Micro Modulation system provides an easily programmable and flexible means of optimizing combustion quality throughout the load requirement range of the boiler/burner unit whilst ensuring the temperature is accurate to within 1 F) and pressure to within 1.5 p.s.i. The positioning accuracy of the direct drive motors controlling the air damper and fuel valve is 0.1 angular degrees at any position in the load range.

At the heart of the system is the control module which contains the micro computer and power supply. The front panel of the control module features a 10.4" Touch Screen.
