Embodiment Construction
[0023] The low-pressure low-calorific-value gas burner of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as figure 1 and figure 2 As shown, the low-pressure low-calorific-value gas burner of the present invention is composed of a gas pipeline 1, an air pipeline 2, a gas collector 3, an air box 4, a gas nozzle 5 (the number is 19), a swirl flame stabilizer 6 (the number 1), short air ducts 7 (the number is 7), ever-burning lamps 8, ultraviolet fire detectors 9, ionization fire detectors 10, combustion chambers 11, and the like.
[0025] The combustion chamber 11 has a double-layer structure, the inner layer is high alumina refractory brick, and the outer layer is aluminum silicate fiber. The bellows 4 is connected to the bottom of the combustion chamber 11 by nuts. The gas collector 3 is connected to the bottom of the bellows 4 by nuts.
[0026] The burner 11 is welded with an ultr...

The invention provides a low-pressure low-heat value gas combustor. An ultraviolet flame detector and an incandescent light are respectively arranged on a combustion chamber; the front of the incandescent light is connected with an ionizing flame detector; an air bellow is fixed under the combustion chamber; a gas collecting device is fixed under the air bellow; a gas pipeline is fixed at one side of the gas collecting device, and an air pipeline is fixed at one side of the air bellow; a plurality of short air pipes are connected to the upper part of the air bellow and arranged in the combustion chamber; the short air pipes are circularly arranged, and the short air pipe is arranged at the circular center; the bottoms of a plurality of gas spray pipes are connected with the gas collecting device and vertically penetrate through the air bellow, and the tops are arranged in the short air pipes connected to the air bellow; the gas spray pipes and the short air pipes are parallel, coaxially jet and are circularly arranged, and the gas spray pipe is arranged at the circular center; and a rotational flow flame holder is fixed at the top of the central gas spray pipe. The invention can stably combust low-pressure low-heat value gas without boosting gas in a cocurrent flow air distribution and rotational flow flame stabilizing combustion way.
Description
technical field [0001] The invention relates to a burner in the petrochemical, metallurgical and electric power industries, which can be applied to hydrogen, blast furnace gas, coke oven gas and other low calorific value greater than 800kcal / Nm 3 , Combustion of low-pressure low calorific value gas with gas pressure less than or equal to 4000Pa. Background technique [0002] At present, in industrial production processes such as petrochemical, metallurgy and electric power, H 2 , CO and other low-pressure low-calorific-value fuel gases. Due to the low proportion of combustible gas components contained in the fuel gas, the combustion efficiency of the common burner is low. Usually, a torch is used to air-burn this part of the gas, resulting in a waste of energy. [0003] At present, the low calorific value gas burners used in China mainly include porous media burners. Due to the premixed combustion method, there are disadvantages of flashback danger and poor load regulatio...
