Abstract
The present invention relates to a kind of burner structures of rear-mounted steam pipe oven, it is connected with horizontal firing section burner hearth in the lower end of vertical uplink section burner hearth, it is connected with horizontal mixing section burner hearth in the upper end of vertical uplink section burner hearth, gas burner is installed outside the other end of horizontal firing section burner hearth, it is equipped with gas cooler in vertical uplink section burner hearth, thermal detector and superheater bank are equipped in horizontal mixing section burner hearth.The present invention uses the arrangement form of rear-mounted burner, the high-temperature flue gas that coal gas is generated by burner combustion, it moves ahead along burner hearth, it turns again uplink, it turns again and washes away superheater bank, uplink area arranges that heat sink, high-temperature flue gas are sufficiently mixed cooling with cooling gas in mixed zone, so that each position of superheater bank is heated evenly, boiler tube burning is avoided to burst；Burner hearth uses c-type arrangement form, extends residence time of the fuel in burner hearth, conducive to fully burning for fuel.
Description
Technical field
The present invention relates to a kind of burner structures of steam pipe oven, and present invention relates especially to a kind of rear-mounted steam to add
The burner structure of hot stove.
Background technology
Steel plant are in the technical process such as steel-making, steel rolling as converter, a large amount of low temperature of heating furnace apparatus for vapour-cooling generation are low
Saturated vapor is pressed, in addition to a small amount of use by oneself, most of low-pressure saturated steam often cannot be utilized rationally, can only be put to idle discharge, both
Environment is polluted, and causes the significant wastage of the energy.
The arrangement form of steam pipe oven burner is varied in steel industry, there is through type, i.e. burner arrangement
In front of superheater surface；Also a vertical shaft is arranged before having heating surface, burner arrangement is in silo bottom.Or because of live place
Limitation, cannot be satisfied coal gas and burns required enough stroke distances, and most of high-temperature flue gas directly wash away superheater surface,
Even if being provided with heat sink before heating surface, but because apart from limited, flue-gas temperature cannot be effective everywhere for superheater surface
Control, cause the boiler tube burning of superheater front row, pipe explosion accident to take place frequently.
Invention content
The purpose of the present invention is overcoming the deficiencies in the prior art, provides and a kind of effectively improving burning for coal gas
The burner structure of the rear-mounted steam pipe oven of rate, the booster frequency of reduction superheater.
According to technical solution provided by the invention, the burner structure of the rear-mounted steam pipe oven, including coal gas combustion
Burner, horizontal firing section burner hearth, vertical uplink section burner hearth, horizontal mixing section burner hearth, gas cooler, thermal detector and superheater tube
Beam；It is connected with horizontal firing section burner hearth in the lower end of vertical uplink section burner hearth, is connected in the upper end of vertical uplink section burner hearth
There is horizontal mixing section burner hearth, gas burner is installed outside the other end of horizontal firing section burner hearth, in vertical uplink section stove
It is equipped with gas cooler in thorax, thermal detector and superheater bank are equipped in horizontal mixing section burner hearth, thermal detector is cooled down with flue gas
Device is connected by signal wire, and superheater bank is arranged in the front of thermal detector.
The length direction of the horizontal firing section burner hearth and the length direction of vertical uplink section burner hearth are vertical setting, vertically
The length direction of uplink section burner hearth and the length direction of horizontal mixing section burner hearth are vertical setting.
The medium position in vertical uplink section furnace height direction is arranged in the gas cooler.
The present invention has the following advantages：
1, using the arrangement form of rear-mounted burner, using the lower space of superheater surface, by gas burner
It is arranged in superheater lower space, steam superheater is compact-sized, and floor space is few；
2, the high-temperature flue gas generated by burner combustion using the arrangement form of rear-mounted burner, coal gas, along stove
Thorax moves ahead, then uplink of turning, then turns and wash away superheater bank, and uplink area arranges heat sink, high-temperature flue gas and cooling gas
It is sufficiently mixed cooling in mixed zone, each position of superheater bank is made to be heated evenly, boiler tube burning is avoided to burst；
3, burner hearth uses c-type arrangement form, extends residence time of the fuel in burner hearth, conducive to fully burning for fuel.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
The present invention is further explained in the light of specific embodiments.
The burner structure of the rear-mounted steam pipe oven, including it is gas burner 1, horizontal firing section burner hearth 2.1, vertical
Uplink section burner hearth 2.2, horizontal mixing section burner hearth 2.3, gas cooler 3, thermal detector 4 and superheater bank 5；In vertical uplink section
The lower end of burner hearth 2.2 is connected with horizontal firing section burner hearth 2.1, and level is connected in the upper end of vertical uplink section burner hearth 2.2
Mixing section burner hearth 2.3 so that by horizontal firing section burner hearth 2.1, vertical uplink section burner hearth 2.2 and horizontal 2.3 structure of mixing section burner hearth
At burner hearth be in " C " font, gas burner 1 is installed outside the other end of horizontal firing section burner hearth 2.1, in vertical uplink
It is equipped with gas cooler 3 in section burner hearth 2.2, thermal detector 4 and superheater bank 5, thermometric are equipped in horizontal mixing section burner hearth 2.3
Device 4 is connected with gas cooler 3 by signal wire, and superheater bank 5 is arranged in the front of thermal detector 4.
The length direction of the length direction of the horizontal firing section burner hearth 2.1 and vertical uplink section burner hearth 2.2 is perpendicular to be set
It sets, the length direction of the length direction and horizontal mixing section burner hearth 2.3 of vertical uplink section burner hearth 2.2 is vertical setting.
The medium position in vertical 2.2 short transverse of uplink section burner hearth is arranged in the gas cooler 3.
The high-temperature flue gas that coal gas is generated by the burning of gas burner 1, moves ahead, then turn along horizontal firing section burner hearth 2.1
Curved rising is disposed with gas cooler 3, high-temperature flue gas exists into vertical uplink section burner hearth 2.23 in vertical uplink section burner hearth 2.2
The cooling gas that vertical uplink section burner hearth 2.2 is sprayed into gas cooler 3 contacts, and is sufficiently mixed through horizontal mixing section burner hearth 2.3.
According to the smoke temperature that the thermal detector 4 before superheater surface measures, to control the amount that gas cooler 3 sprays into cooling gas.Flue gas
Temperature is controlled effectively, then washes away superheater bank 5, and 5 each position of superheater bank is heated evenly, and avoids boiler tube burning,
Cause booster.
