Embodiment
A kind of high efficiency burnt gas Natural Circulation HRSG, such as Fig. 1, including body of heater 1, drum 2, blast tube 3, some risings
Pipe 4, upper header 5, lower collecting box 6, down-comer 7, with blast tube 3 in body of heater 1, drum 2 is located at blast tube 3 to drum 2
Top, drum 2 is respectively equipped with water inlet pipe and steam (vapor) outlet 11, steam-water separator is provided with drum 2, and one end of down-comer 7 connects
Steaming bag 2, the other end connection lower collecting box 6 of down-comer 7, is communicated with some tedges 4, tedge between lower collecting box 6 and upper header 5
4 in blast tube 3, such as Fig. 2, and tedge 4 is vertical using front end face 41, left surface 42, rear end face, right flank successively head and the tail
The cross section to be formed that connects is square and overall into wavy upper hose, combustion gas in front end face 41, rear end face and blast tube 3
Trend is vertically arranged, and the trend of combustion gas be arranged in parallel in left surface 42, right flank and blast tube 3, and front end face 41 width
The respectively greater than width of left surface 42, right flank, the surface of tedge 4 is provided with some bar-shaped troughs 10, and bar-shaped trough 10 is by upper hose
One end extend to the other end.
This kind of high efficiency burnt gas Natural Circulation HRSG, is square and overall Cheng Bo by the way that upper hose is set into cross section
