This preheating device is creative to be connected by import one, outlet one with boiler cycle flue.By import two, go out Mouth two is connected with boiler back end ductwork to be passed through.
Therefore, the flue gas in boiler cycle flue and back-end ductwork can enter in the present apparatus, to make in preheating part Heat pipe fully absorbs above-mentioned heat.Moreover, boiler smoke discharge can also be made to reach standard.
In the air preheater of above-mentioned boiler, the quantity of the ontology is two: ontology one and ontology two, above-mentioned Ontology one is connected with ontology two by ring flange, and ontology one is connected with shell one by ring flange, ontology two and shell two It is connected by ring flange.
In the air preheater of above-mentioned boiler, the shell one, ontology one, ontology two and shell two are from left to right It is arranged.
In the air preheater of above-mentioned boiler, above-mentioned shell one, ontology one, the side of ontology two and shell two are equal Flush.
Its structural compactness can be improved in this way.
There is heating fin in the air preheater of above-mentioned boiler, outside the heat pipe.
In the air preheater of above-mentioned boiler, the heating fin is twist coated on the outside of heat pipe.
In the air preheater of above-mentioned boiler, the axle center for heating fin in the form of sheets and heat fin and heat pipe Line direction is obliquely installed, and several heating fins are parallel to each other.
The thermal efficiency of heat can be effectively improved by heating fin.
In the air preheater of above-mentioned boiler, the ontology one and ontology two are all had for being connected with hook Hanging ring.
Whole device can easily be moved by hanging ring.
In the air preheater of above-mentioned boiler, the shell one, shell two and two lower part of ontology are with use In the stabilizer blade with ground face contact.
Guarantee that device stabilization is placed on the ground by stabilizer blade.
In the air preheater of above-mentioned boiler, the import one is located at two side of shell, and the outlet one is located at One top of shell.
Compared with prior art, the air preheater of this boiler is since boiler cycle flue and back-end ductwork can be to warm Pipe is heated, and therefore, heat utilization ratio is relatively high.
Meanwhile shell one, shell two and preheating part are both connected to together, structure is also fairly simple compact, has very high Practical value.
