Abstract
The utility model relates to a normal-pressure gas or oil fired of tube-free fire box type, comprising a combustor, a combustion chamber, a boiler outer cylinder, a pre-bending fire tube box, a fuel chamber, a fuel exhaust hole and a backflash chamber. The structure that bending fire boxes are welded between the fuel chamber and the backflash chamber is adopted, the bending fire boxes have the heat transfer function and can effectively solve the problem of cold and hot expansion flexible stress, and meanwhile, the bending fire boxes in different return arrangement can suit c so as to utilize energy sources more effectively. The bending fire boxes replace the traditional heat exchange tubes to decrease the high cost because the prior miniature normal-pressure boiler uses a great amount of tubular products and lower the processing manufacture difficulty.
Description
Technical field
The utility model relates to a kind of nothing and manages fiery boxlike normal pressure gas fuel boiler, and this boiler comprises horizontal or vertical.
Background technology
General gas fuel boiler structure form mostly is the steel pipe Welding Structure greatly at present, because the tube material price is higher, the use of a large amount of tubing causes the boiler manufacturing cost to increase, and manufacturing processing technic requires high.
The utility model technology is directed to this, adopts the steel plate welding to bend the structure of fiery box in normal-pressure boiler, has promptly saved tubing and has reduced cost, can effectively solve the flexible stress problem of cold and hot expansion because employing bends fiery box elastic construction again.Simultaneously, different backhauls are arranged bends fiery box and can adapt to the boiler load dynamic change, utilizes the energy more efficiently, and it is simple to make processing.
Summary of the invention
The utility model purpose is, provide a kind of nothing to manage fiery boxlike normal pressure gas fuel boiler, this boiler by burner, combustion chamber, boiler outer cylinder body, bend fire tube box, smoke-box, exhaust opening in advance and the chamber of strile-bacing is formed, adopt smoke-box and strile-back and weld the structure that bends fiery box in advance between the chamber, bend fiery box and bear heat transmission function; Bend the distinctive elasticity of flexure structure of fiery box and can effectively solve the flexible stress problem of cold and hot expansion.Simultaneously, different backhauls are arranged bends fiery box and can adapt to the boiler load dynamic change, utilizes the energy more efficiently.Because utilization bends fiery box and replaced traditional heat exchanger tube, thereby it is expensive because of what use tubing to cause in a large number to reduce existing small atmospheric boiler, reduction process for machining and manufacturing difficulty.
A kind of nothing described in the utility model is managed fiery boxlike normal pressure gas fuel boiler, this boiler by burner, combustion chamber, boiler outer cylinder body, bend fire tube box, smoke-box, exhaust opening in advance and the chamber of strile-bacing is formed, upper end in boiler outer cylinder body (3) is smoke-box (5) fixedly, the bottom of smoke-box (5) is connected with the chamber of strile-bacing (7) by bending fire tube box (4) in advance, and the bottom of the chamber of strile-bacing (7) is provided with combustion chamber (2).
The fire tube box (4) that bends in advance of the bottom welding of smoke-box (5) is arranged for parallel longitudinal.
What strile-back top, chamber (7) welding bends fire tube box (4) in advance for laterally being arranged in parallel.
One end of smoke-box (5) is provided with exhaust opening (6).
One end of combustion chamber (2) is connected with burner (1).
A kind of nothing described in the utility model is managed fiery boxlike normal pressure gas fuel boiler, the fiery box that bends in this boiler is born heat transmission function, bend the distinctive elasticity of flexure structure of fiery box and can effectively solve the flexible stress problem of cold and hot expansion, simultaneously, different backhauls are arranged bends fiery box and can adapt to the boiler load dynamic change, utilizes the energy more efficiently.Bend fiery box in advance and be welded in parallel between combustion chamber and smoke-box, because bend the variation of shape, the flue gas nature forms two return, three backhauls and four backhauls in the boiler operatiopn in two chambers and pipeline.The utility model is simple in structure, make easy to process, low cost of manufacture.Nothing described in the utility model is managed fiery boxlike normal pressure gas fuel boiler all applicable to vertical or horizontal boiler.

The specific embodiment
Further describe and provide embodiment below in conjunction with accompanying drawing.
A kind of nothing described in the utility model is managed fiery boxlike normal pressure gas fuel boiler, this boiler is by burner, the combustion chamber, the boiler outer cylinder body, bend the fire tube box in advance, smoke-box, the exhaust opening and the chamber of strile-bacing are formed, upper end in boiler outer cylinder body 3 is smoke-box 5 fixedly, one end of smoke-box 5 is provided with exhaust opening 6, the bottom of smoke-box 5 is connected with the chamber 7 of strile-bacing by bending fire tube box 4 in advance, the fire tube box 4 that bends in advance of the bottom welding of smoke-box 5 is arranged for parallel longitudinal, what strile-back 7 tops, chamber welding bends fire tube box 4 in advance for laterally being arranged in parallel, the strile-back bottom of chamber 7 is provided with combustion chamber 2, and an end of combustion chamber 2 is connected with burner 1.
In use, flame fully burning in combustion chamber 2 that burner 1 is produced by gas or oil, form the first burning backhaul, the first burning backhaul heat exchange amount passes to medium (water) by combustion chamber 2 cylindrical shells, the flue gas that produces enters smoke-box 5 by the fiery box 4 that bends in advance that the chamber 7 of strile-bacing enters the welding that laterally is arranged in parallel, bend in advance in fiery box 4 tube banks, short near inboard fiery box tube bank flow process, be the 0.5-1 backhaul, tube bank long flow path near the outside, be the 1-2 backhaul, mix in the backhaul at this, flue gas,, is discharged through flue 6 by bending in advance flue gas that fiery box 4 enters smoke-box 5 finishes last exchange heat (backhaul+1) in smoke-box 5 after heat transferred medium (water) by the thin plate wall.Boiler described in the utility model is the horizontal boiler of normal pressure or the vertical boiler of normal pressure.
