Flue gas self-circulation low-nitrogen heat storage burner control method and device

Abstract

The invention discloses a flue gas self-circulation low-nitrogen heat storage burner control method and device, and belongs to the field of heat storage burners, the flue gas self-circulation low-nitrogen heat storage burner control method comprises the following steps that S1, fuel gas is ignited at the ignition end of one burner and forms flames in a hearth; the air blower is started, and combustion-supporting air enters the heat storage box body from the air pipe through the four-way valve to support combustion of flames; s2, an induced draft fan is started, flue gas generated by combustion in the hearth in the step S1 is led out through a four-way valve, a high-pressure induced draft fan is started to lead part of the led-out flue gas into a mixing pipeline, the flue gas enters a heat storage box through regulation and control of an air valve and is mixed into combustion-supporting air, oxygen-deficient combustion of a burner is achieved, and nitric oxide generated in the combustion process is reduced; smoke with carbon dioxide and nitrogen as main components is introduced and mixed into combustion-supporting air, generation of nitric oxide is restrained in the combustion process by reducing the oxygen content in the combustion-supporting air, and oxygen-deficient combustion of the burner is achieved.

Description

technical field [0001] The invention relates to the field of regenerative burners, and more specifically relates to a control method and device for a low-nitrogen regenerative burner that utilizes flue gas self-circulation and combustion process decommissioning. Background technique [0002] The traditional regenerative burner uses high-temperature combustion-supporting air mixed with gas for combustion. Due to the high temperature of the combustion-supporting air, the center temperature of the flame is high on the basis of full combustion, resulting in the production of a large amount of nitrogen oxides during the combustion process, resulting in air pollution. Pollution. At the same time, the high temperature in the furnace will also cause the generation of nitrogen oxides. Contents of the invention [0003] Aiming at the problems existing in the prior art, the first object of the present invention is to provide a low-nitrogen regenerative burner control method with flu...
