1. automatic ignition and blowout protection controller 7 detect that altar lamp gaseous-pressure signal 12, main gaseous-pressure signal 11 and air blast 20 such as to start at the signal, open air electric control valve 22, purge pyrolysis furnace burner hearth 1.
2. after purging 10 minutes, electric igniter 6 starts, and produces continuous print electric spark at altar lamp 29 head, and fuel gas magnetic valve 8 is opened simultaneously, lights altar lamp 29 of igniting.
3. the timing from electric igniter 6 starts of the timer in controller 7:
After the time of 3.1 arrival settings, if flame do not monitored out by flame detector 4, then another digital output modul signal is provided to go to participate in closing main fuel air valve 11 to DCS, electric igniter 6 power-off simultaneously, igniter fuel pneumoelectric magnet valve 8 is closed, and " loss of ignition " indicator lamp is bright, electric bell gives a warning.Burner hearth purges, and whole program returns to initial state.
After the time of 3.2 arrival settings, if it is normal that flame monitored out by flame monitor 4, then igniter 6 stops sparking, indicator lamp of " lighting a fire successfully " is bright, there is provided a digital output modul signal to go to open main fuel pneumoelectric magnet valve 11 to DCS simultaneously, " main fuel air valve is opened " indicator lamp is bright, and fuel device enters running status.
4. after flame ignition success, igniter 6 is exited burner hearth to prevent heat damage.
5. burner runing adjustment working procedure:
Air/fuel ratio is adopted automatically to regulate.That is: sampled by thermocouple 26 in spent acid pyrolysis furnace 1, in temperature controller 23, PID carries out data processing, and transmits fill order, air/fuel ratio adjusting valve 21 regulating gas in proportion to air electric control valve 22:
5.1 establish thermoelectricity in stove: 26 collecting temperatures are lower than design temperature on temperature controller 23, in temperature controller, PID drives large instruction → electronic execution machine open greatly to electric control valve on air pipe line 22 transmission, air pressure improves, before flow increase → burner, air/fuel ratio adjusting valve 21 air side is improved by pressure guiding pipe pressure, gaseous-pressure is also improved in proportion in combustion gas side, and gas flow increases.
5.2 to establish in stove thermocouple collecting temperature higher than design temperature on temperature controller 23, in temperature controller, PID turns down to electric control valve on air pipe line 22 transmission pass small instruction → electronic execution machine, air pressure reduces, before flow reduction → burner, air/fuel ratio adjusting valve 21 air side is reduced by pressure guiding pipe pressure, combustion gas side also reduces gaseous-pressure in proportion, and gas flow reduces.
Through automatically repeatedly regulating, make furnace temperature homeostasis on temperature controller 23 design temperature, temperature-controlled precision is ± 5 DEG C.
6. when fire box temperature reaches the numerical value of technique initialization, atomizing air pipeline magnetic valve 9 is opened, and first passes into atomizing air to spent acid nozzle 5, and then spent acid line solenoid valve 10 is opened, pass into spent acid to spent acid nozzle 5, spent acid sprays into the cracking of pyrolysis furnace 1 burner hearth after nozzle head atomization.For ensureing that spent acid obtains good atomizing effect, require that spent acid pressure is not less than 0.6MPa (absolutely), atomization air pressure is not less than spent acid pressure.
If 7. in burner normal course of operation, flame surprisingly extinguishes, main flame detector 3 can't detect flare up fire, will close altar lamp gas electromagnetic valve 8, main gas solenoid valve 11 and spent acid magnetic valve 10, and send signal alarm to control room alarm 28.
