More Information
Summary:The invention discloses a gas fuel burner with long and short flames, a control method of the gas fuel burner and a heating furnace. The gas fuel burner with the long flame and the short flame comprises an air inlet main pipeline, a fuel inlet main pipeline, a short flame gas nozzle, a short flame air nozzle, a long flame gas nozzle and a long flame air nozzle, and the air inlet main pipeline is communicated with the short flame air nozzle and the long flame air nozzle. The fuel gas inlet main pipeline is communicated with the short flame gas nozzle and the long flame gas nozzle; the gas flow speed of the short flame gas nozzle is controlled to be 15 m/s-25 m/s, and the air flow speed of the short flame air nozzle is controlled to be 20 m/s-40 m/s; and the gas flow speed of the long flame gas nozzle is controlled to be 25 m/s-100 m/s, and the air flow speed of the long flame air nozzle is controlled to be 40 m/s-100 m/s. The gas fuel burner can provide long flames and short flames at the same time, and theref
