OPERATION

IR Detector

The S702 and S802 viewing head models use a Germanium 

photodiode, which responds to IR radiation/flicker in the flame. 

Flame flicker is caused by the combustion, or forced air 

injected in to the flame. Combustion air can be mixed with the 

fuel (pulverized coal) or can be introduced separately. In either 

case, forced air is introduced in such a way as to aid the 

combustion process. This air is usually made turbulent by 

causing it to swirl with spin vanes located in the burner throat. 

Flame flicker is created when turbulent air mixes with the 

flame. It is composed of random frequencies and the amount 

of high frequency flicker is dependent on the fuel and the 

burner.

The S702, S702PF and S802 viewing head models respond 

to flicker frequencies above 33Hz. All flicker frequencies below 

the filters are ignored, so it is important to sight the viewing 

head on the highly turbulent portion of the flame that contains 

the higher frequencies. The location of the higher frequencies 

can be predicted by examining the burner with regard to 

where the turbulent air enters the flame. The optimum scanner 

location is parallel to the burner center line (Fig. 16). The use 

of a swivel mount is encouraged to allow for line of sight.

UV Detector

The S706, S706PF and S806 viewing head models use the 

UVTron tube, with a spectral response of 185-260nm and 

peak response of 210nm to ultraviolet radiation. The output of 

the detector is a pulse stream of randomly spaced pulses 

whose average rate is proportional to the UV radiation present 

in the flame. The UV radiation is a direct result of the
