Abstract
Waste Heat Boiler superheater, belongs to environmental protection cogeneration technology field.Comprise low-temperature zone, middle-temperature section, the high temperature section three-stagesuperheater arranged successively, it is characterized in that: the bundle diameters of described low-temperature zone, middle-temperature section, high temperature section three-stagesuperheater is d, the transverse pitch of high temperature superheater tube bank is d+102mm ~ d+122mm, longitudinal pitch d+62mm ~ d+90mm; The transverse pitch of medium temperature overheater tube bank is d+82 ~ d+102mm, longitudinal pitch d+62mm ~ d+92mm; The transverse pitch of low temperature superheater tube bank is d+82mm ~ d+102mm, longitudinal pitch d+32mm ~ d+92mm.The tube bank arrangement of the utility model superheater, makes flying dust more free settling, effectively avoids flying dust to pile up, and improves heat exchange efficiency, ensures boiler load, improves economy; Reduce the flue-gas temperature entering high temperature superheater, make it be no more than 650 DEG C, reduce the high temperature corrosion that flue gas produces.
Description
Technical field
The utility model belongs to environmental protection cogeneration technology field, is specially Waste Heat Boiler superheater.
Background technology
Along with the raising of people's living standard, social economy's development, generation increases day by day, and burning electricity generation becomes the important means of refuse disposal.But in Refuse Incineration Process, if pipe is improper apart from arranging, the unsuitable sedimentation of flying dust, is attached on superheater pipeline, reduces heat exchange efficiency; Enter the flue-gas temperature of high temperature superheater easily more than 650 DEG C, produce high temperature corrosion; The flue gas produced during waste incineration enters in horizontal flue, and because flue gas flow rate is high, caking property is large
,exchange hot side directly washes away, and causes dust stratification serious.
Utility model content
The purpose of this utility model is: by regulating the tube pitch of Waste Heat Boiler superheater, make in flow of flue gas process, flying dust is not easily piled up, and reduces high temperature corrosion, improves heat exchange efficiency.
The purpose of this utility model is achieved in that Waste Heat Boiler superheater, comprise low-temperature zone, middle-temperature section, the high temperature section three-stagesuperheater arranged successively, it is characterized in that: the bundle diameters of described low-temperature zone, middle-temperature section, high temperature section three-stagesuperheater is d, the transverse pitch of high temperature superheater tube bank is d+102mm ~ d+122mm, longitudinal pitch d+62mm ~ d+90mm; The transverse pitch of medium temperature overheater tube bank is d+82 ~ d+102mm, longitudinal pitch d+62mm ~ d+92mm; The transverse pitch of low temperature superheater tube bank is d+82mm ~ d+102mm, longitudinal pitch d+32mm ~ d+92mm.
The tube bank arrangement of the utility model superheater, makes flying dust more free settling, effectively avoids flying dust to pile up, and improves heat exchange efficiency, ensures boiler load, improves economy; Reduce the flue-gas temperature entering high temperature superheater, make it be no more than 650 DEG C, reduce the high temperature corrosion that flue gas produces.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model comprises low-temperature zone, middle-temperature section, the high temperature section three-stagesuperheater 1,2,3 arranged successively, the bundle diameters of low-temperature zone, middle-temperature section, high temperature section three-stagesuperheater 1,2,3 is d, the transverse pitch d1 of high temperature superheater tube bank is d+102mm ~ d+122mm, longitudinal pitch d2 is d+62mm ~ d+90mm; The transverse pitch d3 of medium temperature overheater tube bank is d+82 ~ d+102mm, longitudinal pitch d4 is d+62mm ~ d+92mm; The transverse pitch d5 of low temperature superheater tube bank is d+82mm ~ d+102mm, longitudinal pitch d6 is d+32mm ~ d+92mm.
