7, The air flow inside of the combustion furnace can be stably
controlled at (5000 ± 500) L / min.
Combustion Systems:
1, The burner: Belt type propane gas burner size of 257mm × 4.5mm,
and opening a total of 242 holes,which arranged in 3 lines of
81,80,81, the diameter of the hole is
1. 35mm, the distance between the holes is 3.2 mm;
2, Equipped with high-precision ball valve to control the gas off;
3, Two flow meters: air flow meter and gas flow meter and control
valve;
4, The front of the combustion tester is provided with a flame stop
tube to prevent the propane gas from tempering, thereby ensuring
the maximum safety of the sample.
5, Combustion angle: horizontal; automatic ignition device; (20
degrees adjustable is optional).
6, The burner can automatically compensate the gas and air
compensation process by computer program,while many traditional
systems have neglected this influence.
