Abstract

The utility model discloses a gas-fired horizontal boiler, which comprises a boiler chamber (3) that is transversally arranged at the middle lower part of the boiler shell (6), a gas combustion engine (1) that is arranged at the ingress of the boiler chamber (3) and a plurality of straight fire tubes (5) whose both ends are respectively communicated with a back smoke chamber (2), a smoke box (7) and a chimney (8). The utility model is characterized in that the gas-fired horizontal boiler also comprises a plurality of bend fire tubes (4) that are arranged in the internal water of the boiler shell (6); one end of the bend fire tube (4) is bend tube; the bend tube end of the bend fire tube (4) is communicated with one end of the boiler chamber that is far away from the gas combustion engine (1); the straight tube end of the bend fire tube (4) is communicated with the back smoke chamber (2). On the basis of the existing gas-fired horizontal boiler, a back fire chamber and a straight fire tube connected with the back fire chamber are cancelled by the boiler, which makes the structure be simple, the cost be decreased; the accident of burning-out the boiler element because of excessive heating is avoided, the durability of the boiler is lengthened, the safety is enhanced, and the boiler thermal efficiency is greater than 90 percent.

Description

The combustion gas horizontal boiler
Technical field
The utility model relates to a kind of boiler, especially a kind of combustion gas horizontal boiler.
Background technology
Because gases such as natural gas, liquefied gas, coal gas have advantages such as burning is clean, free from environmental pollution, progressively become a kind of high-grade fuel commonly used.Especially natural gas, along with western gas east is sent, price is relatively cheap, has been used as boiler oil in place with good conditionsi.Therefore, gas fired-boiler also just arises at the historic moment, and progressively is widely used.
Though,,, and generally prolong with traditional cell structures that strile-backs of horizontal internal combustion boiler such as fire coal, fuel oils so the gas fired-boiler of prior art generally adopts horizontal boiler because of flue gas backhaul weak point, so the thermal efficiency is lower because vertical boiler has advantages such as floor space is little.It mainly is made up of shell, heat-insulation layer, gas burning machine, flue, straight fire tube, the chamber of strile-bacing, time smoke-box, straight smoke pipe, smoke box and chimney etc.Enter after the flue internal combustion of the flame of being located at the gas burning machine ejection of flue import department (is equipped with water) in being located at shell middle and lower part and be located at away from the dried back of the body formula outside the combustor other end shell strile-back indoor (first backhaul), flue gas enters (left side) through straight fire tube (second backhaul) and returns in smoke-box, enters atmosphere through straight smoke pipe (the 3rd backhaul) and (right side) smoke box and the chimney be located at outside the shell again.
Because adopt traditional cell structure that strile-backs, there is following defective in this boiler: one, boiler structure is complicated, strile-back outdoorly must establish heat-insulation layer in addition, so, produce, the installation, maintenance cost is higher.Two, owing to the chamber of strile-bacing does not have water cooling for dried back of the body formula, its locular wall easily burns out because of overheated, has both reduced the service life of boiler, has reduced security performance again.Three, red-hot flue gas is back in the interior smoke pipe of shell after entering the chamber of strile-bacing again, has wasted partial heat energy, has reduced the thermal efficiency of boiler.
The utility model content
The technical problems to be solved in the utility model is, overcomes above the deficiencies in the prior art, provide a kind of simple in structure, cost is low, long service life, the thermal efficiency be greater than 90% and the reliable combustion gas horizontal boiler of security.
Technical solution of the present utility model is, on the basis of existing combustion gas horizontal boiler, cancellation strile-back chamber and coupled straight fire tube etc. provide a kind of combustion gas horizontal boiler with following structure.It comprises the flue of laterally being located at middle and lower part in the shell, is located at the gas burning machine of flue import department and the straight smoke pipe that some two ends are communicated with back smoke-box and smoke box and chimney respectively, and be characterized in: it also comprises the some curved fire tubes of being located in the interior water of shell; One end of described curved fire tube vial is a bend pipe, and an end of the bend pipe of described curved fire tube is communicated with flue that end away from gas burning machine, and an end of described curved fire tube straight tube is communicated with back smoke-box.
The operation principle of this combustion gas horizontal boiler is as follows: after the flame of the gas burning machine ejection of being located at flue import department burnt in flue, red-hot flue gas oppositely entered back smoke-box through curved fire tube, and flue gas turns back and enters straight smoke pipe.The flue gas that is fully absorbed heat enters atmosphere by smoke box through chimney.Meanwhile, the medium-water in the shell, the heat transfer by heating surfaces such as flue, curved fire tube, straight smoke pipes constantly is heated as steam or hot water, for use.
After adopting above structure, the utility model is compared with the combustion gas horizontal boiler of prior art, has following remarkable advantage and beneficial effect.
One, owing to cancelled the parts such as chamber and straight fire tube that strile-back, the structure of boiler is become simply by complexity, thereby reduced production, installation and maintenance cost.
Two, owing to cancelled the dried back of the body formula chamber of strile-bacing, adopt the curved fire tube structure of water back of the body formula, all boiler heating surfaces that promptly comprise curved fire tube are water and surround, all boiler parts can not burnt out because of overheated, so, both prolonged service life of boiler, improved the security performance of boiler again.
Three, owing to adopt curved fire tube directly to be communicated with flue (right-hand member) and return smoke-box, solved the problem of red-hot smoke backflow simply, the heat energy of boiler is utilized fully, thereby the thermal efficiency that has guaranteed boiler is greater than 90%.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is this combustion gas horizontal boiler structural representation.
Fig. 2 is Figure 1A-A cross-sectional schematic.
The specific embodiment
As shown in Figure 1 and Figure 2, shell 6 is horizontal cylindrical shape obturator.Insulation layer (not drawing among the figure) is arranged outside the shell 6.Left end is provided with the cylindrical shape flue 3 of opening and laterally is located at middle and lower part in the shell 6, and the left end of flue 3 stretches out the left end of shell 6, its junction welded seal.The import department of flue 3 (opening part is located at the left end of flue 3 among the figure) is provided with gas burning machine 1.Shell 6 inner furnaces 3 left outer top is provided with time smoke-box 2 of sealing.The chimney 8 that shell 6 upper right side outer walls are provided with smoke box 7 and communicate with it.Shell 6 inner furnaces 3 outer some (this example is 9) straight smoke pipes 5 that are provided with.One end of described straight smoke pipe 5 is communicated with back smoke-box 2, and the other end of straight smoke pipe 5 is communicated with smoke box 7.There is water in described shell 6 inner furnaces 3 and straight smoke pipe 5 outer most of spaces.More than be prior art.
The characteristics of the utility model combustion gas horizontal boiler are to cancel former combustion gas horizontal boiler traditional strile-back chamber and coupled straight fire tube, and replace with curved fire tube 4.Promptly adopt some (this example is 8) to bend fire tube 4, described curved fire tube 4 is located in the interior water of shell, one end of described curved fire tube 4 vials is a bend pipe, one end of the bend pipe of described curved fire tube 4 is communicated with flue 3 that end (being the right-hand member of flue 3 among the figure) away from gas burning machine 1, and an end of the straight tube of described curved fire tube 4 is communicated with back smoke-box 2.
