Description

Space gas Dual-regeneration type burner
Technical field
The present invention relates to space gas Two-cuff Technique technical field, more particularly, to a kind of space gas Dual-regeneration type burner.
Background technology
Current space gas Two-cuff Technique technology has obtained length at home because successfully blast furnace gas being applied to heater for rolling steel Long development.Even to this day, because the furnace pressure of double-regenerative heating furnace is high and fluctuates larger, the longevity such as heat storage, reversal valve Order the series of factors such as short fault rate is high, heat storage configuration is improper, nozzle structure is unreasonable, lead to the stove of double-regenerative heating furnace The life-span of lining and burner is generally short than normal reheating furnace, and the maintenance of double-regenerative heating furnace and maintenance cost occupy height not always Under.Among these in addition to control and design reasons, nozzle structure is unreasonable most important.
There is problems with space gas Dual-regeneration type burner of the prior art:
(1) adopt rectangle burner block or the space gas of integrated poured rectangle to lead to common space gas Dual-regeneration type burner more Road, whole heat storage tank front portion is arranged on furnace side within the walls.Because single burner volume is generally larger, this requires must on furnace lining Must reserve or an integrated poured very big rectangle hole.Require with heatproof to seal, burner block periphery all can not adopt Heat-insulation layer, can only adopt heavy castable;Further, since accumulation of heat casing has occupied very big furnace lining area, on furnace lining Do not have enough spaces that anchored brick and heat-insulation layer are set;These make furnace lining self structure extremely unreasonable:Because no protecting Warm layer leads to furnace lining external skin temperatures high;No enough anchored bricks lead to furnace lining self structure intensity cannot ensure;More because rectangle burns Sealing problem between mouth brick and furnace lining cannot be guaranteed, under the higher working environment of double-regenerative heating furnace furnace pressure, just It is easy to occur furnace lining cracking string fire, furnace lining and burner to burn with anger, the problem of furnace lining and the burner lost of life.
(2) adopt honeycomb ceramics as heat storage more common space gas Dual-regeneration type burner, typically adopt heat storage duct Horizontally disposed mode, that is, the medium in accumulation of heat body flow to as horizontal direction, this makes the heat storage bottom of high temperature section subject Very big pressure, is easy to generating material creep damage at high temperature, leads to heat storage cracking, deformation, the storage of portion Hot body subsides, and the heat storage heat exchange efficiency ultimately resulting in whole heat storage tank declines, exhaust gas temperature overtemperature, the heat storage lost of life.
(3) the many media flow to be distributed using porous floater guide block in heat storage tank of common space gas Dual-regeneration type burner, are subject to Structure limits, and the flowing space before and after heat storage is little, does not have the header of enough expanding section volumes, it is difficult to ensure that Jie in accumulation of heat body Matter flow uniformity, the burner in particular for honeycomb body structure, so that the availability of heat storage is relatively low, designs and reality The effect of application is inconsistent.
(4) common space gas Dual-regeneration type burner because being limited by honeycomb strength it is impossible to increase in short transverse, in order to Ensure enough heat storage configuration amount, single burner often can only increase the size in casing width (i.e. furnace superintendent direction), make Obtain accumulation of heat casing and take bigger furnace lining space, horizontal layout is also extremely crowded.
All of these factors taken together leads to the maintenance of double-regenerative heating furnace and maintenance cost can not to be in any more always, and furnace lining is warm Loss is big, and energy consumption remains high, operating environment also extreme difference.
Thus, the present inventor relies on experience and the practice being engaged in relevant industries for many years, proposes a kind of space gas double heat storage type Burner, to overcome the defect of prior art.
