A kind of sintering cup test ignition method, its concrete grammar and step are:
1, in computer, work out program control ignition procedure.
2, computer program-control ignition drops to sintering rim of a cup.
3, computer program-control starts air blast, and residual gas in pipeline is purged.
4, purge after 25-35s, computer program-control unlocking electronic igniter and flame detection head, postpone to open secondary magnetic valve after 2 s, provides a small amount of combustion gas to carry out prefiring; Meanwhile, detected temperatures situation is fed back to computer by flame detection head, and computer judges that according to design temperature whether prefiring is successful; Computer as unsuccessful in prefiring will cut out secondary magnetic valve, and re-start igniting.
If 5 prefiring successes, computer program-control is opened main solenoid valve, formally lights a fire, and igniter is normally worked and started timing; Combustion gas is penetrated by air outlet slit with the flow velocity that is greater than 5m/s from gas outlet ejection, combustion air with the pressure that is greater than 2kPa; combustion gas and combustion air are strengthened premix burning rapidly in the premix chamber that flame detection head is housed; through all the joining of the equal matching board of flame, guarantee that flame is uniform and stable in the temperature in protective cover exit again.
6, computer, by parameter control firing temperature and the duration of ignition set, reaches after setting-up time when the duration of ignition, and computer program-control is closed main solenoid valve, secondary magnetic valve and air blast.
7, the computer control ignition original position that rises back, igniting finishes.
Beneficial effect of the present invention is:
Reasonable in design of the present invention; can save manpower and space; can in short distance, guarantee that the burning focus (maximum temperature point) of flame is just on protective cover pelvic outlet plane; realize automatic control ignition process; ignition success rate is high; can improve fuel combustion efficiency, guarantee the accuracy rate of sintering cup test.
