Abstract
The invention discloses a kind of heat exchanger for gas fired-boiler, including flue gas coil and coolant coil, flue gas coil fits together side by side with coolant coil, at described flue gas coil with described coolant coil binding face, it is provided with some flue teeth in described flue gas coil side, it is correspondingly arranged on the some grooves coordinated with described flue tooth in described coolant coil side, described flue tooth stretches in described coolant coil, and described flue gas coil internal pipeline trend moves towards identical with described coolant coil internal pipeline.A kind of heat exchanger for gas fired-boiler of the present invention, it is achieved that fully absorbing of waste-gas heat, it is to avoid the waste of heat and fuel, adds heat exchange area to greatest extent simultaneously, improves heat exchange efficiency.
Description
Technical field
The present invention relates to heating equipment manufacturing technology field, a kind of heat exchanger for gas fired-boiler.
Background technology
Under the background of energy-saving and emission-reduction at present, pulverized-coal fired boiler is gradually eliminated, and gas fired-boiler is then widely applied.But combustion
It is not utilized that the waste gas discharged after gas boiler combustion gas contains amount of heat, causes the waste of heat, and heat exchange at present sets
It is extremely difficult to higher heat exchange efficiency for contact surface is less.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of heat exchanger for gas fired-boiler, it is achieved that waste-gas heat
Fully absorb, it is to avoid the waste of heat and fuel, add heat exchange area to greatest extent simultaneously, improve heat exchange efficiency.
In order to realize foregoing invention purpose, the present invention provides techniques below scheme:
A kind of heat exchanger for gas fired-boiler, including flue gas coil and coolant coil,
Flue gas coil fits together side by side with coolant coil,
At described flue gas coil with described coolant coil binding face, it is provided with some cigarettes in described flue gas coil side
Road tooth, is correspondingly arranged on, in described coolant coil side, the some grooves coordinated with described flue tooth, and described flue tooth is stretched
Enter in described coolant coil,
Described flue gas coil internal pipeline trend moves towards identical with described coolant coil internal pipeline.
Further, the air inlet of described flue gas coil bottom it, and lays respectively at described in its top, gas outlet
Flue gas coil two ends,
The inlet of described coolant coil is corresponding with position, described gas outlet, the liquid outlet of described coolant coil and institute
State air inlet position corresponding.
Further, the binding face between described flue gas coil and described coolant coil is arcwall face, described patch
The recessed side in conjunction face is towards described coolant coil.
A kind of heat exchanger for gas fired-boiler of the present invention, in fact achieve fully absorbing of waste-gas heat, it is to avoid heat
With the waste of fuel, add heat exchange area to greatest extent simultaneously, improve heat exchange efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic front view of a kind of heat exchanger for gas fired-boiler of the present invention；
Fig. 2 is the schematic top plan view of a kind of heat exchanger for gas fired-boiler of the present invention.
Detailed description of the invention

1,
Flue gas coil 6 fits together side by side with coolant coil 1,
At described flue gas coil with described coolant coil binding face, it is provided with some cigarettes in described flue gas coil side
Road tooth 7, is correspondingly arranged on, in described coolant coil side, the some grooves coordinated with described flue tooth, and described flue tooth is stretched
Enter in described coolant coil,
Described flue gas coil 6 internal pipeline trend moves towards identical with described coolant coil 1 internal pipeline.
The air inlet 3 of described flue gas coil 6 at its top, gas outlet 5 is bottom it, and lays respectively at described flue gas Serpentis
Shape pipe 6 two ends,
The inlet 4 of described coolant coil 1 is corresponding with position, described gas outlet 5, the liquid outlet of described coolant coil 1
2 is corresponding with described air inlet 3 position.
Binding face between described flue gas coil 6 and described coolant coil 1 is arcwall face, described binding face recessed
Enter side towards described coolant coil 1.
A kind of heat exchanger for gas fired-boiler of the present invention, it is achieved that fully absorbing of waste-gas heat, it is to avoid heat and
The waste of fuel, adds heat exchange area to greatest extent simultaneously, improves heat exchange efficiency.
