In blast furnace gas, main component is inert nitrogen gas (N 2) and carbon dioxide (CO 2), ratio up to about 75%, fuel gas carbon monoxide (CO) and a small amount of hydrogen (H 2) ratio accounts for about 25%.In blast furnace gas, combustible gas component ratio is few, the low (700 ~ 900kCal/Nm of calorific value 3), theoretical temperature combustion low (about 1300 DEG C), these character are all unfavorable for the burning of blast furnace gas.
At present, in the commercial Application to low-calorie fuel gas burings such as blast furnace gases, in order to ensure the smooth combustion of coal gas, most of combustion type mixes to burn calorific value high heavy oil, natural gas or coal dust in coal gas.Along with the development of technology, in low capacity gas boiler, many employings multitube gas burner, coal gas is at Bottomhole pressure, air is in the outer flowing of pipe, mix at burner outlet place, multitube gas burner flame is longer, single burner heat input rate is lower, generally be arranged in boiler furnace corner, in order to add intense steady combusting, need to set up gas heater to heat to improve in the temperature of coal gas or boiler furnace to the coal gas before entering boiler-burner and set up regenerative apparatus, along with the increase of boiler capacity, be subject to the restriction of single gas burner thermal power and as fired fuel atmospheric pressure, the layout of burner and combustion stability all can be subject to larger impact.
Utility model content
The purpose of this utility model is exactly the defect for prior art, provides a kind of Dual-cyclone low heat value gas combustion burner.Specifically a kind of with fuel gas with low heat value (500 ~ 1800Kcal/Nm 3) be the Dual-cyclone gas burner of fuel, be mainly used in the gas combustion apparatus in the gas fired-boiler of 7.5MW ~ 150MW Gas Generator Set and various waste gas combustion furnace.
The technical solution adopted in the utility model is: comprise the Gas Pipe connecting combustion gas, connect the warm-air pipe of hot-air, combustion gas cyclone, hot-blast swirler, burning torch, ignition air gun, igniting fire monitor equipment and main fire monitor equipment, also comprise the central air hose connecting hot-air, described central air hose, Gas Pipe and warm-air pipe are arranged successively from inside to outside and are communicated to the same port of export, the described port of export connects venturi type nozzle, described combustion gas cyclone and hot-blast swirler are all arranged on reducing place of venturi type nozzle, and circumferentially direction is evenly axially arranged, described hot-blast swirler is arranged at combustion gas cyclone outer ring with one heart, described central air hose is communicated to combustion gas cyclone inner ring, described burning torch, ignition air gun and igniting fire monitor equipment are arranged in central air hose.
Further preferred structure, tapping on the blade that described main fire monitor equipment is arranged at combustion gas cyclone.
Preferred structure further, the blade quantity of described combustion gas cyclone is 8 ~ 25, and centrally axis is uniform, and the opacity of blade is 1.05 ~ 1.2, and the established angle of blade and central axis angle are 40 ~ 60 °.
Preferred structure further, the blade quantity of described hot-blast swirler is 8 ~ 25, and centrally axis is uniform, and the opacity of blade is 1.05 ~ 1.2, and the established angle of blade and central axis angle are 25 ~ 70 °.
In technique scheme, combustion gas cyclone and hot-blast swirler all can produce clockwise by the difference of setting angle or be rotated counterclockwise air-flow, but the air-flow rotation direction of combustion gas and hot blast should be consistent, and strengthens circulating flow strength further.
Preferred structure further, the import department of described central air hose and warm-air pipe is provided with throttle setting.
Venturi type jet pipe and combustion gas and air double-cyclone organically combine by the utility model, and add central air hose, a small amount of air is provided to its eddy flow district center position, to strengthen the stability of blast furnace gas combustion, combustion gas and hot-air can produce strong swirling motion after axial rotational flow blade, both are not only allowed to mix fully early, and high-temperature flue gas all can be entrainmented in the mixing external boundary of rotating jet and center, prevent the tempering of gas burner and de-fiery phenomenon with adding the extruding of venturi type nozzle and extremely efficient, can the burning of stability and safety when ensure that combustion gas does not need the equipment such as regenerative apparatus in combustion heater or stove in steam generator system, and the combustion gas resistance of burner and wind resistance less.
Originally novel have following beneficial effect: (1) sufficient combustion, and steady combustion is effective, tempering and de-fiery phenomenon can not occur, improve combustion gas utilization rate and boiler efficiency; (2) single burner heat input rate is large, and load regulation rate is large, and boiler can regulate by increasing and decreasing the number of burners put into operation when underrun; (3) burner drag characteristic is good, can adapt to the situation of gaseous-pressure fluctuation; (4) structure is simple, and swirl vane adopts axial direct blade shape, convenient processing and manufacture; (5) regenerative apparatus in combustion heater or stove need not be added, save boiler construction cost; (6) Gas Pipe and warm-air pipe adopt flange form to be connected, and dismantle easy to use, reduce burner maintenance cost; (7) pollutant emission is low, particularly NO xand CO.
