Embodiment 1

[0029] combined with figure 1 , this embodiment provides a burner that can adapt to a variety of gas fuels, including a casing 1 and a gas supply pipe 2, the casing 1 is provided with an intake chamber 11 and a combustion chamber 12 at both ends, and the intake The chamber 11 is provided with a gas-assisting interface 13, and both ends of the gas supply pipe 2 are respectively provided with a gas interface 21 and a nozzle cavity 22; the end of the gas supply pipe 2 with the nozzle cavity 22 is located in the casing 1, and the The nozzle chamber 22 is connected to the combustion chamber 12; the nozzle chamber 22 is used for accommodating the gas nozzle 3, and a gas flow channel 23 is provided between the gas nozzle 3 and the side wall of the nozzle chamber 22, and the gas flow channel The effective flow area of ​​23 is adjustable.

[0030] It can be understood that, the effective flow area of ​​the gas flow channel 23 can be adjusted in various ways. The size of the gap betwe...

Embodiment 2

[0049] This embodiment provides a burner that can adapt to a variety of gas fuels. Based on the structure and principle described in Embodiment 1, the nozzle chamber 22 is communicated with the intake chamber 11 through a premixing channel 24, so that the gas During combustion, a small part of the auxiliary gas is injected into the nozzle cavity 22 through the premixing channel 24 on the gas supply pipe 2 to be premixed with the fuel gas, which can improve the stability of the flame.

Embodiment 3

[0051] This embodiment provides a burner that can adapt to various gas fuels. Based on the structure and principle described in Embodiment 1 or Embodiment 2, the gas supply pipe 2 is located at the outer periphery of one end of the combustion chamber 12 . The flow vane 9 is used to make the oxidant gas and the fuel gas fully mixed through the swirling flow vane 9 .

Abstract

The invention discloses a burner adapting to various gas fuels, and relates to the technical field of heating equipment. According to the technical scheme, the combustor comprises a shell and a fuel gas supply pipe, a gas inlet chamber and a combustion chamber are arranged at the two ends of the shell respectively, the gas inlet chamber is provided with a combustion-supporting gas connector, and a fuel gas connector and a sprayer cavity are arranged at the two ends of the fuel gas supply pipe respectively; the end, provided with the spray head cavity, of the fuel gas supply pipe is located in the shell, and the spray head cavity is connected with the combustion chamber. The nozzle cavity is used for containing a fuel gas nozzle, a fuel gas flow channel is arranged between the fuel gas nozzle and the side wall of the nozzle cavity, and the effective flow area of the fuel gas flow channel is adjustable. According to the burner provided by the invention, the effective flow area of the gas flow channel between the gas nozzle and the side wall of the nozzle cavity is adjustable, and the flow or speed of gas ejection can be dynamically adjusted, so that the same burner can meet the combustion requirements of different fuels.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a burner that can adapt to various gas fuels. Background technique [0002] There are many types of high-temperature furnace gas fuels, including natural gas with high calorific value, artificial gas with low calorific value, and hydrogen fuel with high calorific value is also used as fuel for high-temperature furnace. However, the calorific value of different fuels is different. For the same burner power, the fuel flow rate is different, and the performance of different fuels is different. The injection speed can avoid hydrogen fuel tempering), and different injection speeds are also required. Therefore, it is difficult for existing burners to adapt to fuels with different calorific values, and each fuel with calorific value needs to be equipped with a dedicated burner. SUMMARY OF THE INVENTION [0003] Aiming at the technical problem that the existing burners are ...
