(V) detailed description of the preferred embodiments

The attached drawing is a concrete embodiment of the utility model. This embodiment includes furnace body 1, and the lower part is equipped with combustion chamber 2 in the furnace body 1, and combustion chamber 2 is equipped with a plurality of groups riser 3 all around, and 3 bottoms of every group riser are connected with down violently pipe 4 respectively, all do not communicate with each other between the lower violently

pipe

4, and 3 tops of every group riser are connected with respectively and violently manage 5, and every two adjacent upper horizontal pipes 5 are linked together, and upper horizontal pipe 5 connects secondary heating pipe 6, and secondary heating pipe 6 connects a plurality of groups of U type pipe 7, and U type pipe 7 end-to-end connection steam outlet pipe 8. A fire baffle plate 9 is arranged below the U-shaped pipe 7. The top of the combustion chamber 2 is connected with a fire collecting plate 10, and the fire collecting plate 10 is provided with a fire collecting hole 11. The upper horizontal pipe 5 is connected with a preheating water tank 12, and the preheating water tank 12 is connected with a flue gas outlet 13.
