Problems solved by technology
[0007] Increased power of pulsating burners: The power of pulsating burners currently used is relatively small, and they are mainly used in household water heaters, food ovens, small boilers, etc. etc., but it has been basically solved by adopting the form of the curved tailpipe), another important reason is that the power of the pulsating burner cannot be adjusted in a wide range by the self-priming method

Embodiment Construction
[0024] Such as figure 1 As shown, the above-mentioned valveless pulsating burner is composed of a mixing chamber 1, a combustion chamber 5, a tailpipe 6, and a smoke decoupling chamber 7. The above-mentioned mixing chamber 1 is provided with one or more gas and air inlet nozzles 2 in the circumferential direction. , outside each spout 2 is an air inlet pipe 3, which links to each other with a blower fan or a gas supply pipe. The number and size of gas and air nozzles 2 in the circumferential direction of the mixing chamber 1 are not limited, that is, the number and size of gas nozzles and the number and size of air nozzles may or may not be equal. During the operation of the burner, gas and air are continuously injected into the mixing chamber 1 through the above-mentioned gas supply pipe 3 .
[0025] Such as figure 1 , figure 2 As shown, gas and air enter the mixing chamber 1 through the gas supply pipe 3 through the nozzle 2, and the airflow direction points to the cente...

The invention discloses a valveless fuel gas pulsation burner, consisting of a mixing chamber, a combustion chamber, a tail pipe and an exhaust smoke decoupling chamber; one or more fuel gas and air inlet nozzles are arranged at the circumference of the mixing chamber, and intake pipes outside every nozzle are connected with a blower or a fuel gas supply pipe. When the burner is in operation, fuel gas and air are continuously supplied, the formed pulsation combustion characteristics is related to the geometric structure of the burner and proportioning relationship of the fuel gas and the air,control and adjustment can be carried out according to the actual different requirements, and the valveless fuel gas pulsation burner has convenient operation, stable working and high efficiency, andis convenient for power amplifying of such burners.
Description
technical field [0001] The invention relates to a valveless gas pulse burner Background technique [0002] The pulsating burner is a burner that works exclusively in the state of acoustic pulsation under the control of certain acoustic conditions. The most widely used pulse burner is the Helmholtz type pulse burner, which is based on the principle of the acoustic Helmholtz resonator. [0003] The Helmholtz type pulsating burner is very similar to the Helmholtz resonator. In structure, it consists of a hollow cavity with a certain volume, and a small diameter hole is opened on one of its walls. A fairly long tailpipe is connected to this hole. The other end has air and fuel inlets and one-way valves. The outlet of the tailpipe is generally equipped with a decoupling chamber with a larger volume, which has the effect of noise reduction, and can ensure the acoustic boundary conditions of the tailpipe outlet plane and the acoustic characteristics of the burner system. Upstre...
