The specific embodiment
To combine accompanying drawing that the utility model is done further detailed description below: present embodiment provided detailed embodiment, but the protection domain of the utility model is not limited to following embodiment being to implement under the prerequisite with the utility model technical scheme.
Embodiment 1: as depicted in figs. 1 and 2; The boiler economizer that the related a kind of and boiler body of present embodiment links into an integrated entity; Comprise: upper collecting chamber 1, exhaust opening 2, endothermic tube 3, smoke box 4, smoke inlet 5 and next part case 7, the upper end of said smoke box 4 is fixedly connected with upper collecting chamber 1, and the lower end of smoke box 4 is fixedly connected with next part case 7; Endothermic tube 3 vertically is arranged between upper collecting chamber 1 and the next part case 7; The upper end of endothermic tube 3 is connected with upper collecting chamber 1, and the lower end of endothermic tube 3 is connected with next part case 7, is respectively equipped with exhaust opening 2 and smoke inlet 5 on the smoke box 4.Said smoke inlet 5 is arranged on the bottom of smoke box 4, and exhaust opening 2 is arranged on the top of smoke box 4 opposite sides.Said endothermic tube 3 is aciculiform pipe or extended surface tube.
Embodiment 2: like Fig. 3 and shown in Figure 4; The difference of present embodiment and embodiment 1 is; Also comprise tube connector 1-1, overhead gage 1-2, following tube connector 1-3 and lower baffle plate 1-4, said overhead gage 1-2 is fixed on the open-mouth of upper collecting chamber 1, and the end of last tube connector 1-1 is fixed on the overhead gage 1-2; Lower baffle plate 1-4 is fixed on the open-mouth of next part case 7, and the end of following tube connector 1-3 is fixed on the lower baffle plate 1-4.
Embodiment 3: like Fig. 5 and shown in Figure 6, the difference of present embodiment and embodiment 1 is, also comprises dividing plate 8, and said dividing plate 8 is fixed in the smoke box 4.Said smoke inlet 5 is arranged on the bottom of smoke box 4, and exhaust opening 2 is arranged on the bottom of smoke box 4 opposite sides.
