Transverse baffle and flat pipe type self-preheating burner

Abstract

The invention discloses a transverse baffle and flat pipe type self-preheating burner. The transverse baffle and flat pipe type self-preheating burner comprises a gas pipeline provided with a gas channel, a combustion improver pipeline in which a combustion improver isolation barrel is inserted and a smoke pipeline in which a smoke isolation barrel is inserted, wherein an annular channel between the combustion improver pipeline and the combustion improver isolation barrel is a combustion improver channel, and the gas pipeline is inserted into the combustion improver isolation barrel; the smoke isolation barrel is sleeved at one end, passing through the combustion improver pipeline, of the combustion improver isolation barrel; one end, passing through the smoke pipeline, of the smoke isolation barrel is connected with a gas collection chamber; an annular channel between the smoke pipeline and the smoke isolation barrel is a smoke channel; a plurality of heat exchange flat pipes are inserted in the smoke channel; and one end of each of the heat exchange flat pipes is communicated with the combustion improver channel and the other end of each of the heat exchange flat pipes is communicated with the gas collection chamber. In the transverse baffle and flat pipe type self-preheating burner, a plurality of heat exchange flat pipes are arranged in the smoke channel, so the heat exchange between a combustion improver and smoke is enhanced, the heat exchange efficiency of the nozzle is improved and the structure of the nozzle is more compact.

Description

technical field [0001] The invention relates to a burner, in particular to a flow splitter flat tube type self-preheating burner suitable for various radiant tube heating furnaces and open flame heating furnaces. Background technique [0002] As we all know, the self-preheating burner is a burner that organically combines the burner body, heat exchange device and combustion device. It effectively uses the exhaust gas generated by itself during combustion to preheat the combustion air for self-combustion When it reaches a certain temperature, it is sent to the front of the nozzle of the burner with almost no heat loss, mixed with gas for intense combustion, and sprayed to the furnace at high speed, under the action of high-speed jet flow and ejection backflow, the furnace temperature is uniform It has the characteristics of compact structure, good temperature uniformity and high degree of automation. It has been widely used in various protective atmosphere radiant tube heat t...
