Surround and be welded on pipe support（3）Go up and channel cover is installed（1）；The steam of the relatively low mass dryness fraction exported from injection boiler radiant section is from steaming
Vapor inlet（11）Pass into seamless steel pipe（6）With elbow（8）The formed circulation passage of welding, absorbs the mass dryness fraction after heat more
High steam is from steam (vapor) outlet（12）Injection boiler steam (vapor) outlet is connected to after out.
Above-mentioned bobbin carriage（2）With channel cover（1）Inwall is provided with the ceramic fiber blanket of insulation（9）.
Above-mentioned insulation fixture（5）Using triangular structure.
Above-mentioned channel cover（1）Using serum cap.
The beneficial effects of the utility model are：The steam for the relatively low mass dryness fraction that original annotation boiler furnace is exported is lifted by the mass dryness fraction
Device makes it be exchanged heat again with high-temperature flue gas, and then further improves its mass dryness fraction；The heat exchange pipeline section that the utility model is mentioned is used
Seamless steel pipe, flue gas is difficult the dust stratification on heat exchanger tube when flowing through light pipe outer wall, heat-transfer effect is good, and operation is safer, and mass dryness fraction is carried
Liter device absorbs heat again can lower the thermal efficiency that exhaust gas temperature improves boiler entirety by a relatively large margin, effectively reduce boiler operatiopn
Cost, it is significant to exploitation viscous crude field, raising heat injection tar productivity, the saving energy.
