Abstract

The high-speed low-nitrogen combustor comprises a lower straight barrel, a center gun is arranged in the lower straight barrel, a center fuel gun and an ignition gun are arranged in the center gun, the front end of the center fuel gun and the front end of the ignition gun are both arranged on a flame stabilizing device, and the flame stabilizing device is arranged at an opening in the front end of the center gun. A first air inlet is formed in the side face of the center gun, a second air inlet is formed in the side face of the lower straight barrel, a plurality of first fuel guns are arranged in the lower straight barrel and evenly and annularly distributed on the periphery of the center gun, and ports of the lower straight barrel, the center gun, the center fuel gun and the first fuel guns are located on the same side. According to the scheme, the nitrogen reduction strategy of staged combustion is adopted, combusted mixed gas is divided into three stages to be combusted in the axial direction, flames diverging from the center to the outer layer are formed, and therefore the combustor has the effects of reducing the oxidation burning loss rate, reducing generation of thermal nitrogen oxide and improving the steel billet yield.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a high-speed low-nitrogen burner for heating furnaces and a combustion method thereof. Background technique [0002] In the production process of the metallurgical industry, the hot rolling heating furnace is a large energy consumer. At present, there is still a lot of room for improvement in the fine control of the stepping heating furnace, which can improve the control accuracy of the heating furnace, reduce energy waste and product loss, and reduce carbon for the entire metallurgical industry. and nitrogen reduction are of great significance; the conventional walking heating furnace refers to the slab with basically the same shape, which moves continuously inside the heating furnace, from the entrance of the heating furnace to the exit under the drive of the roller, and the heating furnace The flame heating furnace steel slab produced by burning the burner arranged at a specif...
