Embodiment Construction
[0013] Below by embodiment, in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
[0014] like figure 1 , figure 2 The shown double-drum water-fire-tube boiler is mainly composed of a boiler furnace 1, two drums 2, a number of furnace tubes 3, a number of fins 4, and a refractory material layer 6, an insulation layer 7, and a heat insulation layer. The refractory material layer 6, the heat insulating layer 7, and the heat insulating layer are all arranged outside the furnace tube, and the refractory material layer 6 is located inside the heat insulating layer 7, and the heat insulating layer 7 is located inside the heat insulating layer. Two drums 2 are arranged in the furnace 1 of the boiler, and the axes of the two drums 2 are parallel to each other. The two drums 2 are connected through several furnace tubes 3 , and fins 4 are arranged between adjacent furnace tubes 3 . There is a gap between the ends of the ...

The invention discloses a double-drum water-fire tube boiler with protection boxes. The boiler comprises a boiler furnace (1) and two boiler drums (2) arranged in the boiler furnace (1). The axes of the two boiler drums (2) are parallel, the two boiler drums are communicated through a plurality of boiler tubes (3), fins (4) are arranged between adjacent boiler tubes (3), gaps are reserved between two ends of the fins (4) and corresponding boiler drums (2), the protection boxes (5) are welded at the connection position of the boiler drums (2) and the roots of the boiler tubes (3), the protection boxes (5) are formed by welding steel plates, the roots of the boiler tubes (3) are covered in the protection boxes (5), the roots of the fins (4) are connected with the outer walls of the protection boxes (5), and the boiler tubes (3), the fins (4) and the protection boxes (5) form a sealing wall together. The boiler can solve the problems of smoke leakage, air admission and burning out of a pouring material on the outer side of a weak link.
Description
technical field [0001] The invention relates to the technical field of boilers, in particular to a double-drum water-fire tube boiler structure with a protective box. Background technique [0002] The double-drum water-fire tube boiler is a commonly used boiler structure at present. There are two drums in the boiler furnace. The axes of the two drums are parallel to each other, and the two drums are connected by several furnace tubes to heat exchange. Fins are welded between every two adjacent furnace tubes, the fins are usually made of flat steel, and the two ends of the fins are respectively welded to the adjacent furnace tubes. The fins have the function of connecting the furnace tube, so that the flue gas does not leak out, the heat does not pass out, and the thermal efficiency is improved. However, limited by the welding process, the root of the fins cannot be welded together with the drum, resulting in a large gap between the drum and the fins, which can only be seal...
