Working process:
When cooking stove is started working, air channel, upper strata wash water valve 16 and lower floor's air channel wash water valve 17 are closed, 6 pairs of burner hearth 2 chargings of burner hearth opening for feed, when fuel height arrives material level check-out console 22 position, by material level induction rod 20, material level inductor block 19 is started to control, stop charging, this moment, air channel, upper strata air intake valve 4 and lower floor's air channel air intake valve 5 were opened, air blast enters upper strata annular passage 9 by air channel, upper strata blast pipe 7, and passes through air channel, upper strata air outlet tube 13 to the interior air blast of burner hearth 2; Simultaneously, air blast enters lower floor's annular passage 10 by lower floor's air channel blast pipe 8, and by vertical direction air outlet and horizontal direction air outlet to the interior air blast of burner hearth 2.First inflammable gas such as liquefied gas are filled with blast inlet 3,1 pair of burner hearth of lighter for ignition, 2 fuel igniting simultaneously, after igniting, air outlet at two-layer air inlet device forms two zone of combustion of height, low zone of combustion is that heat zone produces carbonic acid gas, is reducing zone above the high combustion layer, and the carbon that carbonic acid gas and reducing zone is scorching hot contacts reduction reaction occurs, generate the inflammable gas carbon monoxide, after gasification, carbon monoxide burns again.When working, cooking stove closes lighter for ignition 1 and inflammable gas entrance.
Lower floor's annular passage 10 is for generation of heat zone, for fuel provides the pyrolysis energy, upper strata annular passage 9 is used for keeping the reducing zone temperature, heat zone is exactly zone of combustion, product is carbonic acid gas, belong to waste gas, the upper strata of heat zone is reducing zone, belong to scorching hot carbon-coating, when the carbonic acid gas that heat zone produces moved to gas outlet 23 by scorching hot carbon-coating, the carbon scorching hot with reducing zone contacted the generation reduction reaction, generates the inflammable gas carbon monoxide, the carbon dioxide reduction that heat zone is produced becomes carbon monoxide, improves the fuel gas rate.Because air outlet divides two-layer even distribution in burner hearth 2 interior space, the wind field, the wind pressure ratio that are diffused into burner hearth 2 are more even, and in burner hearth, temperature is also just more even.Regulate air channel, upper strata air intake valve 4 and lower floor's air channel air intake valve 5, make the zone of combustion temperature between 600 degree are spent to 650, just can control cooking stove and not produce the slagging scorification phenomenon in combustion processes.Diaphragm seal 21 can prevent gas leaking, air outlet 23 output inflammable gass.Along with the consumption of fuel, the material level step-down, material level check-out console 22 starts feed mechanism by material level induction rod 20 and material level inductor block 19, burner hearth begins charging, when fuel height arrives material level check-out console 22 position, control material level inductor block 19 by material level induction rod 20 and start to control, stop charging.And so forth, make the cooking stove non-stop run.
When cleaning upper strata annular passage 9 and lower floor's annular passage 10, air channel, upper strata wash water valve 16 and lower floor's air channel wash water valve 17 are opened, and air blast is discharged the impurity in the air channel by air channel, upper strata blow-off pipe 14 and lower floor's air channel blow-off pipe 15 respectively by sewage draining exit 18.
