A kind of sintering cup test is used ignition method, and its concrete grammar and step are:
1, the program control ignition procedure of establishment in computer.
2, the computer program-control ignition drops to the sintering rim of a cup.
3, computer program-control starts air blast, and residual gas in the pipeline is purged.
4, behind the purging 25-35s, computer program-control unlocking electronic igniter and flame detection head postpone to open secondary magnetic valve behind 2 s, provide a small amount of combustion gas to carry out prefiring; Simultaneously, the flame detection head feeds back to computer with the detected temperatures situation, and computer judges according to design temperature whether prefiring is successful; To close secondary magnetic valve like the unsuccessful computer of prefiring, and light a fire again.
5, if prefiring is successful, computer program-control is opened main solenoid valve, formally lights a fire, and the igniter operate as normal also picks up counting; Combustion gas is penetrated by air outlet slit with the flow velocity greater than 5m/s from gas outlet ejection, combustion air with the pressure greater than 2kPa; Combustion gas and combustion air are strengthened premix and burning rapidly in the premix chamber of flame detection head is housed; Through all the joining of the equal matching board of flame, guaranteed that flame is uniform and stable in the temperature in protective cover exit again.
6, computer is by the parameter control firing temperature and the duration of ignition set, and after reaching setting-up time the duration of ignition, 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 guarantee in short distance that flame burning focus (maximum temperature point) is on the protective cover pelvic outlet plane just, realize the automatic control ignition process, ignition success rate is high; Can improve fuel combustion efficiency, guarantee the accuracy rate of sintering cup test.
