Product, gas steam generator substantially use following 2 kinds of frame modes: 1, using the heat exchanger tube of serpentine configuration (see Fig. 1)；2, it changes
Heat pipe uses bellows (see Fig. 2).Although both modes biggish increase heat exchange area of energy, area compared with straight collimator
Greater efficiency is high not enough, especially the heat exchange area of fume side, and the total length for resulting in the need for heat exchanger tube is still longer.Therefore,
Need to provide a kind of gas steam generator that the thermal efficiency is high solution the deficiencies in the prior art.
Utility model content
To overcome the shortcomings of existing technologies, the utility model provides a kind of combustion easy to make, at low cost, the thermal efficiency is high
Gas steam generator.
A kind of gas steam generator that the thermal efficiency is high, including flue shell, flue shell is interior to be equipped with combustion chamber, heat exchange
Pipe, water inlet, exhaust chamber and steam outlet, the combustion chamber are arranged in the bottom of flue shell, are equipped in the combustion chamber
The top of at least one burner, the combustion chamber is connected with heat exchanger tube；The top of flue shell is arranged in the exhaust chamber,
The exhaust chamber is connected with the top of heat exchanger tube, and the exhaust chamber is connected with exhaust pipe, sets on the flue shell
There are water inlet and steam outlet.
To further realize the utility model, draft fan is additionally provided between the exhaust chamber and exhaust pipe.
To further realize the utility model, the quantity of the heat exchanger tube is at least one.
To further realize the utility model, the heat exchanger tube includes straight tube and the finned tube that is nested in straight tube, institute
It states and is axially arranged with several grooves along it on the lateral wall of finned tube, form fin between the adjacent groove.
To further realize the utility model, the straight tube is made of stainless steel material, and the finned tube uses aluminium
Matter is made.
To further realize the utility model, the groove is parallel to each other and is arranged at equal intervals.
The utility model has the beneficial effects that
The gas steam generator of the utility model, including straight pipe type heat exchanger tube, the heat exchanger tube and gas steam generator
The heat exchange area of fume side in steel pipe can be significantly increased, the quantity of heat exchanger tube and the length of heat exchanger tube can be greatly reduced, significantly
Weld seam quantity and length are reduced, risk of leakage is reduced, reduces cost, improves the thermal efficiency, and easy to make, the at low cost, thermal efficiency
It is high.
Detailed description of the invention
