Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of flue.
Fig. 3 is a vertical arrangement schematic diagram of the present utility model.
Among the figure: 1, chimney intake, 2, superheater, 3, attemperator, 4, tedge, 5, down-comer, 6, drum, 7, the steam inlet pipe, 8, outlet pipe, 9, heat pipe steam generator, 10, heat pipe economizer, 11, water inlet pipe, 12, flue outlet.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: the heat pipe-type waste heat boiler that the utility model provides is made of superheater 2, heat pipe steam generator 9, heat pipe economizer 10 and drum 6, and superheater 2, heat pipe steam generator 9, heat pipe economizer 10 and drum 6 all can adopt insulating refractory to constitute.Superheater 2 is connected with chimney intake 1, and the steam inlet pipe 7 of superheater 2 links to each other with drum 6, and superheater 2 is divided into two parts, is provided with attemperator 3 in the middle of two parts.Heat pipe steam generator 9 is connected to form closed circuit by tedge 4 and down-comer 5 with drum 6; The water inlet end of heat pipe economizer 10 links to each other with steam inlet pipe 7, and the water side of heat pipe economizer 10 is connected with outlet pipe 8, and outlet pipe 8 links to each other with drum 6, and the end of heat pipe economizer 10 is connected with flue outlet 12.
