Abstract
The utility model discloses a ladle-preheating device with gas fuel, which is a device for baking and preheating the ladle for metallurgy. The existing ladle baking technology with low-calorie fuels can not make the preheating temperature of the ladle obtain a satisfied level. The ladle-preheating device with gas fuel uses exhaust heat exhausted by the device to simultaneously preheat combustion-air and gas fuels; the ladle-preheating device with gas fuel comprises a ladle baking cover, a center double-pipe type combustion nozzle and a smoke pipe which can simultaneously preheat the combustion-air and the gas fuels. When the utility model uses the gas of a generating furnace, the preheating temperature of the ladle can also reach more than 1100 DEG.
Description
The utility model is about metallurgical ladle being carried out the equipment of preheating.In existing ladle baking technology, general is carried out preheating to combustion air, and this under condition as producer gas, is difficult to make the ladle preheat temperature to reach gratifying degree using low calorie fuels.
The purpose of this utility model just is to provide a kind of ladle preheating device, when using gases fuel, can carry out preheating simultaneously to combustion air and fuel gas, to improve the ladle preheat temperature.
Ladle preheating device provided by the utility model mainly comprises: one is lined with the roasting clad that heat-barrier material is used for preventing the ladle heat radiation and collects waste heat gas; The waste gas smoke pipe that annular flue is arranged, gaseous fuel is heated by the central tube of this flue, and the outer wall of annular flue is an interlayer pipe, and spiral flow deflector is arranged, and is used for the heating flame air; A center cartridge type long flame burns to be chewed, and pipe is communicated with the fuel gas that heated in it, and outer tube is communicated with the combustion air that heated.
The major advantage of this device is: gaseous fuel and the combustion air of participating in burning carried out preheating simultaneously, can reclaim more waste heat from waste hot gas, improve the recycling degree of fuel heat; Useless fume afterheat by recycling temperature constantly rises progressively improves the temperature of combustion products, thereby reaches higher ladle preheat temperature.Utilize producer gas also can reach more than 1100 ℃ for fuel.
Accompanying drawing is depicted as the example that this device is used for vertical placement ladle.Roasting clad 2 drops on the upper limb of ladle 1.The roasting clad 2 in waste hot gas edge in the ladle enters the circular passage of smoke pipe, introduces chimneys 10 by passage afterbody exhaust outlet 9 and discharges; Central tube 4 links to each other with gaseous fuel inlet tube 7 at afterbody, and the other end of central tube 4 is chewed 3 with center tubular type burning and linked to each other; The interlayer pipe 5 of band spiral flow deflector links to each other with blast inlet pipe 8 at afterbody, and the hot air outlet of interlayer pipe front end is chewed 3 through bend pipe 6 and center tubular type burning and linked to each other; Through combustion air that waste hot gas heated and gaseous fuel enter the center cartridge type burn chew 3 after, chew ejection and in ladle, form a long flame by burning ladle is heated.
Roasting clad, smoke pipe and burning are chewed and are formed a whole, by a bearing support.Roasting clad can be taked various mode with respect to the motion of ladle.
Owing to use this device to improve the ladle preheat temperature, can reach indirectly and save the good result of smelting energy consumption and improving metallurgical quality.
