Embodiment
It is below in conjunction with the accompanying drawings and real in order to be more clearly understood that above-mentioned purpose of the present utility model, feature and advantage
Example is applied to be described further the utility model.It should be noted that in the case where not conflicting, embodiments herein and reality
Applying the feature in example can be mutually combined.
Many details are elaborated in the following description to fully understand the utility model, still, this practicality
New to implement using different from other modes described here, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment 1, as shown in Figure 1, Figure 2, Figure 3 shows, the present embodiment provide a kind of full condensation augmentation of heat transfer gas fired-boiler, with biography
The condenser boiler of system is compared, and has huge change in the size or structure that the present embodiment is provided in either volume
Change, first, the full condensation augmentation of heat transfer gas fired-boiler that the present embodiment is provided includes boiler body 1 and is arranged on boiler body
The fixed mount 11 of 1 lower section, boiler body 1 and fixed mount 1 shape can be consistent with existing shape, and the present embodiment is carried
Port 12 is provided with the boiler body 1 of confession and the interior flue 3 communicated with port 12 of boiler body 1 is arranged on, in combustion
Burn and burner 2 is set at mouth 12, the one end of flue 3 away from port 12 is provided with return combustion chamber 4, is communicated with return combustion chamber 4
Short smoke pipe 5, specifically, the perforate on the locular wall of return combustion chamber 4, for setting short smoke pipe 5, in short smoke pipe 5 away from return combustion chamber 4
One end is communicated with flue 6, equally, is also that perforate is for setting up short smoke pipe 5 on the locular wall of flue 6, in order to save space, it is to avoid
The waste of energy, short smoke pipe 4 is arranged on the top of flue 3, in the present embodiment, remote in flue 6 in order to effectively utilize waste heat
One end from short smoke pipe 5 is communicated with energy-saving appliance 7, and condenser 8 is communicated with the one end of energy-saving appliance 7 away from flue, wherein, energy-saving appliance
7 and condenser 8 be arranged at the top of boiler body 1, energy-saving appliance 7 and condenser 8 are prior art, therefore in the present embodiment
In, it is not added with detailed description.In order to preferably utilize high-temperature flue gas, making high-temperature flue gas, residence time is more in boiler body 1
It is long, meanwhile, the effect that traditional short smoke pipe and long smoke pipe cooperate is reached, in the present embodiment, short smoke pipe 5 is threaded flue,
The tie 51 for rotating flow-disturbing air-flow is provided with threaded flue, twisted strip 51 and screw thread make fluid rotate flow-disturbing fortune
It is dynamic, so that the structure of whole fluid changes, the flow path of rotating fluid is added, the fluid velocity for pressing close to wall increases
Plus, add the disturbance of boundary layer fluid, and boundary layer fluid and main fluid mixing, therefore heat transfer is able to significantly strengthen.
The thermal efficiency of so boiler is also to significantly improve.
Compared with conventional boiler, the boiler that the present embodiment is provided eliminates traditional front smoke box, long smoke pipe, rear smoke box
Three traditional backhauls, while adding the structure of energy-saving appliance, are changed to two backhauls by design, and convection current is increased from the second backhaul and is heated
Area, flue gas leaves boiler from flue, and with respect to three-pass boiler flue gas for the discharge of rear smoke box, this is more reasonably structure shape
Formula.Because from the point of view of whole boiler combustion structure and Temperature Distribution, boiler front portion is the minimum region of temperature, can also so be increased
Plus the reduction space of boiler smoke temperature.
In order to further improve the thermal efficiency, the purpose of energy-conservation is reached, in the present embodiment, tie 51 is spiral knob
Band, more specifically, the pitch of tie 51 are incremented by successively from return combustion chamber 4 to the direction of flue 6, and the effect so done can be high
The residence time of warm flue gas is longer, and the easy rough air of energy, reaches the more preferably thermal efficiency.
Equally, in order to further preferably utilize high-temperature flue gas, the purpose more preferably utilized of energy is reached, in this reality
Apply in example, arc of the short smoke pipe 5 along the flue 3 uniform top for being arranged on flue 3 in a row-shaped, such layout is set, can
There is the comprehensive utilization using energy, make the water in boiler body is greater area of to be contacted with short smoke pipe, make capacity usage ratio more preferably.
It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model
Limitation, any those skilled in the art are changed or are modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change is applied to other fields, but every without departing from technical solutions of the utility model content, according to this reality
Any simple modification, equivalent variations and the remodeling made with new technical spirit to above example, still fall within this practicality new
The protection domain of type technical scheme.
