Determine the water inlet connection of water beam 8.When the superheat steam temperature that preheating section fixes the outlet of water beam 8 is too high or too low, by desuperheating water
Desuperheating water in road 14 is delivered to preheating section and fixed in water beam 8, by adjusting the Desuperheating water regulating valve 13 on the desuperheat water route 14, control
System enters the spray water flux that preheating section is fixed in water beam 8, so as to reach the purpose of control superheat steam temperature.
Embodiment 2：
As shown in Fig. 2 as different from Example 1, it is to be arranged on preheating section walking beam that superheated steam, which produces water beam,
Preheating section movable water beam 11, the preheating section that steam water interface produces water beam and then includes being arranged in preheating section fixed beam fix water beam
8th, the bringing-up section of bringing-up section fixed beam fixes water beam 7, the soaking zone being arranged in soaking zone fixed beam fixes water beam 6, is arranged on
Bringing-up section movable water beam 10 on bringing-up section walking beam and the soaking zone movable water beam 9 being arranged on soaking zone walking beam.Point
With two circulating water outlets on header, one of circulating water outlet fixes water beam 6 with soaking zone successively, bringing-up section fixes water
Beam 7 and preheating section are fixed water beam 8 and are connected in series, i.e., soaking zone fixes the water inlet of water beam 6 and one on distribution header 4 follows
Ring water out connects, and preheating section fixes the delivery port of water beam 8 and the steam water interface inlet communication of drum；Distribute on header 4
Another circulating water outlet successively with entrance step device 5, soaking zone movable water beam 9, bringing-up section movable water beam 10 and outlet
Step device 12 is connected in series, i.e., the water inlet of entrance step device 5 connects with another circulating water outlet on distribution header 4
It is logical, export the delivery port of step device 12 and the steam water interface inlet communication of drum.Apparatus for vapour-cooling in the present embodiment
The Desuperheating water regulating valve 13 for being also equipped with desuperheat water route 14 and being arranged on desuperheat water route 14, the water inlet in desuperheat water route 14 with
The delivery port of entrance step device 5 is connected, and the delivery port in desuperheat water route 14 is connected with the water inlet of preheating section movable water beam 11.
Outside feedwater (~30 DEG C) is squeezed into drum 2 by feed pump 1, and the water in drum 2 is beaten by hot water circulating pump 3
Enter to distribute in header 4, be redistributed to soaking zone and fix in water beam 6 and entrance step device 5.Fixed into soaking zone in water beam 6
Hot water flow through that soaking zone fixes water beam 6, bringing-up section fixes water beam 7 successively and after preheating section fixes water beam 8, heat absorption forms carbonated drink
Mixture enters in drum 2, and the resistance in flow process overcomes by hot water circulating pump 3, forms a forced circulation process；Enter
Hot water in entrance step device 5 flows through soaking zone movable water beam 9 and bringing-up section movable water beam 10 successively, and heat absorption forms carbonated drink
The laggard inlet/outlet step device 12 of mixture, is subsequently entered in drum 2, and the resistance in flow process relies on 3 grams of hot water circulating pump
Clothes, form a forced circulation process.Steam water interface caused by above two-way is in drum 2 after separation, and saturation water is again
Secondary squeezed into by hot water circulating pump 3 in water beam absorbs fume afterheat；Saturated vapor then enters in preheating section movable water beam 11, absorbs
Turn into superheated steam after waste heat and be sent into external steam pipe network.
When the superheat steam temperature that preheating section movable water beam 11 exports is too high or too low, after entrance step device 5
The desuperheat water route 14 being introduced into is sent in preheating section movable water beam 11, is adjusted by adjusting the desuperheating water in the desuperheat water lines 14
Valve 13, the spray water flux that control enters in preheating section movable water beam 11, so as to reach the purpose of control superheat steam temperature, now
Desuperheat water route 14 can move together with movable water beam.
The present invention has reclaimed burner hearth inner support steel billet in walking beam furnace running, the fixation water for promoting steel billet to advance
Waste heat in beam and movable water beam, while fixed using the preheating section for being arranged in low-temperature region in walking beam furnace burner hearth
Water beam or preheating section movable water beam control superheated steam outlet temperature as steam superheater by desuperheating water all the way, from
And preheating section fixation water beam or preheating section movable water beam not overtemperature are controlled, the steel billet weight advanced in energy safety supports burner hearth,
Produce the high superheated steam of energy figure.Simultaneously because what is flowed through in preheating section fixation water beam or preheating section movable water beam was
Vapours, the more saturated steam of temperature is high, and contrast is fixed in water beam or preheating section movable water beam to come through supersaturation water with preheating section
Say, with burner hearth flue gas heat transfer temperature difference reduce, cause heat exchange amount to reduce, thus the present invention apparatus for vapour-cooling take away it is remaining
Heat is less, and the fuel consumption of whole walking beam furnace is also corresponding less.
In summary, the present invention had both improved the energy figure of walking beam furnace waste heat recovery, reduced step-by-step movement again
The fuel consumption of heating furnace.
Describe to be vaporized according to the walking beam furnace of the production superheated steam of the present invention in an illustrative manner above with reference to accompanying drawing
Cooling device.It will be understood by those skilled in the art, however, that the step-by-step movement of the production superheated steam proposed for the invention described above
