According to the characteristics of biomass gas, a forced premixed combustion mode was adopted to design the nozzle, ejector and burner of the igniter, and the method of stabilizing the flame was also studied.Under the condition of certain air-fuel ratio, Gas flow rate and ignition parameters were tested.The optimal flow rate of biomass gas was obtained as0.121m3 / s-1, the flame temperature was as high as1561 ℃, and the flame length was 1.06m.The application showed that the ignition The device has the advantages of high flame temperature, strong adaptability, convenient operation, etc. The pre-combustion time is obviously shortened and the cost is greatly reduced as compared with the previous use of the oil gun.
