Embodiment

[0030] Such as figure 1 As shown, the upper plate 5 and the air preheating channel of the present invention are both a cylinder, and the diameters of the upper plate 5 and the air preheating channel are much larger than their respective heights, so that the upper plate 5 and the air preheating channel are in the same shape All are disc-shaped. At the same time, the air preheating channel is fixed on the upper end surface of the upper plate 5, and a bottom barrel 6 is arranged on the lower end surface of the upper plate 5, and the bottom barrel 6 and the air preheating channel are fixed with the upper plate 5 as In one piece, during installation, the bottom bucket 6 needs to be placed inside the fire well mouth of the fire channel.

[0031] The structure of the air preheating channel is as follows image 3 , 4 As shown, there is an upper large through hole 16 and two upper small through holes 17 on the cylinder of the air preheating passage. The upper large through hole 16 ...

Abstract

The invention discloses an injector gas fume preheating efficient combustor, mainly comprising an upper wall (5) and an air preheating channel and a bottom bucket (6) respectively fixed at the upper end and lower end of the upper wall; the combustor is characterized in that the bottom bucket (6) is internally provided with a fuel gas preheating pipeline (7), the lower end of a hybrid tube (2) is connected with a pipe clamp reducing nipple (3) in the bottom bucket (6) through the air preheating channel and the upper wall (5); the inlet and outlet of the fuel gas preheating pipeline (7) are connected with the hybrid tube (2), meanwhile, the wall of the bottom bucket (6) is further provided with a gas fume inlet (11) connected with the pipe clamp reducing nipple (3).The invention can effectively reuse the high temperature gas fume in a flame path, can not only fully preheat fuel gas which enters the flame path to raise temperature thereof rapidly but also have very good thermal vibrationtransmission effect.

Description

technical field [0001] The invention relates to a burner, which is a high-efficiency jet-suction smoke preheating burner. Background technique [0002] At present, most of the burners used in domestic carbon anode roasting furnaces are mechanically adjusted air distribution and direct injection burners. The air distribution of this kind of burner is not easy to control, and the air intake volume does not match the gas input volume, so it often causes insufficient combustion in the fire channel, or local overburning. When the combustion is not sufficient, the gas with a lower temperature is equivalent to blowing cold air into the furnace, and at the same time, the uncontrolled mechanical air door continuously sucks in cold air into the furnace under the action of negative pressure in the furnace. Under these dual effects, the thermal efficiency of the gas is low, and the furnace temperature fluctuates greatly, which is difficult to control. A large amount of gas is wasted, ...
