extend to the main burner is adjustable according to site requirement. Pilot burner

5.4 Combustion Air

Air passing through the burner for combustion must contain 13% or more oxygen.

Combustion air pressure difference between burner (shown as A and B in figure 1) should

be at the range of 2-8 mbar, optimum operation is obtained at 5-8 mbar. Profiling of the

process stream is required.

Follow parameters should be at specific range when VFI84 series burners are applicated

–

Maximum exhaust temperature of upstream of burner: 600 °C

–

Maximum exhaust temperature of downstream of burner: 900 °C

–

Maximum hot exhaust pressure difference between burner: 8 mbar (A and B pressure

difference in figure 1)

–

Minimum hot exhaust pressure difference between burner: 2 mbar (A and B pressure

difference in figure 1)

–

Minimum exhaust oxygen content: 13%.

–

When hot exhaust pressure drop of the burner is 5 mbar, the exhaust flue gas

turndown ratio can be about 2. The ratio increases when pressure drop gets higher.

–

Maximum burner fuel turndown ratio will be 26 when the pressure drop between the

burner is 5 mbar

–

Maximum ignition capacity:50 kw (with natural gas and fresh air)

–

Maximum flame length:3 times length of the burner cone diameter.

–

Flame supervision: UV scanner only

–

emission: typically, less than 3000 ppm.

–

CO emission: less than 100 ppm if combustion chamber is 700 °C or hotter, and the

incoming fume stream contains at least 16% oxygen by volume

Figure 4 horizontal axis is inlet temperature of the process stream, use the actual inlet

temperature curve, read up to the curve representing the desired stream outlet

temperature and then left is the KW/hr. required per cubic meter of process stream.

Multiply this figure times the cubic meter of process stream flow at high fire. This is the
