Although this method reduces the production of nitrogen oxides to a certain extent, because the temperature of the combustion-supporting air is relatively low, especially in winter, adding a large amount of low-temperature combustion-supporting air will not be able to fully burn, and the unburned combustion-supporting air will bring The heat of the furnace is taken away, resulting in the loss of heat energy and reducing the combustion efficiency

Embodiment 1
[0036] An ultra-low nitrogen burner is provided with a gas pipeline 1, a combustion-supporting air pipeline 21, a return flue gas pipeline 23, an ignition branch 20, and a burner body 14. The gas pipeline, combustion-supporting air pipeline, return flow There are valves on the flue gas pipeline and the ignition branch, a blower 22 on the combustion-supporting air pipeline, and an induced draft fan 24 on the return flue gas pipeline; the combustion port of the burner body is arranged in the furnace 13, and the burner body and The gas pipeline and the combustion-supporting air pipeline are connected, and the ignition branch is connected with the gas pipeline and the combustion-supporting air pipeline. It is characterized in that: the gas pipeline is provided with two gas inlets: gas inlet one and gas inlet 2. The gas entering from gas inlet 1 is directly passed into the burner port of the burner, and the gas entering from gas inlet 2 is passed into the return flue gas pipeline to...

The invention discloses an ultra-low nitrogen combustor and a combustion method thereof. The ultra-low nitrogen combustor is provided with a fuel gas pipeline, a combustion supporting air pipeline, a backflow smoke pipeline, an ignition branch and a combustor body. The fuel gas pipeline, the combustion supporting air pipeline and the backflow smoke pipeline are provided with valves. The combustor body communicates with the fuel gas pipeline and the combustion supporting air pipeline. The ignition branch communicates with the fuel gas pipeline and the combustion supporting air pipeline. The ultra-low nitrogen combustor is characterized in that the fuel gas pipeline is provided with two fuel gas inlets including the first fuel gas inlet and the second fuel gas inlet, fuel gas entering from the first fuel gas inlet is directly led into a combustion opening of the combustor, fuel gas entering from the second fuel gas inlet is led into the backflow smoke pipeline, and a mixed gas led-in combustion opening with the low fuel gas and backflow smoke mixing heat value is formed; and fuel gas, combustion supporting air and mixed gas of backflow smoke and fuel gas are led into the combustion opening of the combustor and are ejected and combusted at the combustion opening of the combustor. The ultra-low nitrogen combustor and the combustion method thereof are suitable for running of various fuel gas furnaces, generation of heating power type nitric oxide is controlled from the source, and the heat efficiency and energy saving and environment-friendly effects of the fuel gas furnaces are greatly improved.
Description
technical field [0001] The invention relates to the technical field of a gas burner, a combustion technology that produces extremely low nitrogen oxides, in particular to an ultra-low nitrogen burner and a combustion method thereof. It is mainly used in combustion systems that use gas as fuel, such as steam boilers, hot water boilers, and industrial kilns. Background technique [0002] Burners that use gas as fuel are important equipment for steam boilers, hot water boilers, and industrial kilns. Whether its design is reasonable and the operation method is appropriate will directly affect whether the gas is completely combusted and whether it produces as little polluting waste gas as possible, which is directly related to the energy-saving and environmental protection effects of the production process. The nitrogen oxide exhaust gas produced by the burner during combustion operation is the main exhaust gas produced by the gas burner, which has a great impact on the atmosphe...
