Abstract
A fuel gas vacuum boiler includes a boiler shell, a furnace, a smoke tube and a heat exchanger arranged in the boiler shell. A vacuum valve is installed in the upper side of the boiler shell. The cross section of the boiler shell is of semicircular structure, with runway-shaped structure in the middle; the heat exchanger adopting U-shaped heat exchange tube bank at the upper side of the boiler shell; the furnace as heating surface adopts corrugated furnace which is arranged in the lower side of the boiler shell; the smoke tube as heating surface adopts one-way threaded smoke tube which is arranged above the furnace. Due to the runway structure adopted in the boiler of this utility model, the width of the boiler body is decreased significantly; the floor space is also saved. The corrugated furnace and the one-way threaded smoke tube adopted on the heating surface can reduce effectively the resistance of the smoke and increase the flow velocity of the smoke, therefore give full play to the high efficient heat transfer characteristics of the threaded tube. The utility model is characterized in simple boiler structure, small steel consumption, simple manufacturing process, low manufacturing costs etc. which can be applied widely to the fields of industrial and domestic heating and hot water providing.
Description
Technical field
The utility model relates to a kind of vacuum boiler, particularly relates to a kind of fuel vapor vacuum boiler that is widely used in industry and civil heating heat supply and clean hot water is provided.
Background technology
Boiler industry generally adopts horizontal three return structures at present, and this structure is used as heat supply and heat supply water, have the following disadvantages, and the furnace binding complexity, steel consumption is big, manufacturing process complexity, manufacturing cost height.
Summary of the invention
The purpose of this utility model provides a kind of shell and adopts the racetrack structure, heating surface adopt corrugated flue and U type heat exchanger tube for worker, the people, build the fuel vapor vacuum boiler that industry provides heating and hot water, in order to overcome the deficiencies in the prior art.
The purpose of this utility model is achieved in that and comprises shell, places flue, smoke pipe and heat exchanger in the shell body, and vacuum valve is installed in the top of shell, it is characterized in that, the cross section of described shell is up and down a semicircular structure, and the centre is the racetrack structure; Heat exchanger adopts U type heat-exchanging tube bundle to place the interior top of shell body; Adopt corrugated flue to place bottom in the shell body as the flue of heating surface; Smoke pipe as heating surface adopts single backhaul threaded flue to place the top of flue.
Compared with prior art,, significantly reduced the body of heater width, saved floor occupying area because shell of the present utility model adopts the racetrack structural design.Heating surface adopts corrugated internal furnace and single backhaul threaded flue structure, can effectively reduce flue gas resistance and improve flue gas flow rate, therefore can give full play to the efficient heat transfer characteristics of screw thread tubule.It is simple to have furnace binding, and steel consumption is little, and manufacturing process is simple, advantage of low manufacturing cost.
Description of drawings
Fig. 1 is the utility model cross-sectional view.
Fig. 2 is a cross section view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
As Fig. 1, the utility model is made up of shell 5, flue 2, smoke pipe 1, heat exchanger 4, vacuum valve 3.Heat exchanger 4 employing U type heat-exchanging tube bundles place the top in the shell 5.Adopt corrugated flue to place bottom in the shell 5 as the flue 2 of heating surface.Smoke pipe 1 as heating surface adopts single backhaul threaded flue to place the top of flue 2.Flue 2 also can adopt straight flue.As Fig. 2, the cross section of shell 5 is up and down a semicircular structure, and the centre is the racetrack structure.
Operation principle of the present utility model: integral body of the present utility model is the horizontal internal combustion furnace structure, the WATER AS FLOW MEDIUM of conducting heat in the middle of being equipped with in the shell 5.Keep a suitable spacing between liquid level and the heat-exchanging tube bundle, water surface top is the vapor space.Automatic combustor is installed in the front portion of boiler furnace, with the oil gas fuel combustion, produces a large amount of heats, pass to intermediate medium water through flue 2 and smoke pipe 1, water is subjected to thermal evaporation to produce steam and heat-exchanging tube bundle carries out phase-change heat-exchange, and with the heating of the system water in the heat-exchanging tube bundle, output is used for heating.Condensed water in the shell after the steam phase transformation falls liquid level after rise, continues to be heated evaporation and so moves in circles in an airtight oxygen-free environment.
Claims (2)
