Abstract
The utility model discloses a kind of normal-pressure hot-water boiler with heat exchanger, including boiler body and the water tank being arranged on above and below body of heater, copper pipe heat exchanger is provided with upper tank.The utility model is that heat exchanger is carried in boiler body, break the structure type of conventional atmospheric boiler, both can guarantee that atmospheric pressure state during boiler operatiopn, can ensure certain pressure of supply water when to the heat supply of ordinarily resident building again, make heat supply stable, and eliminate secondary network heat-exchange unit.The heat transfer coefficient of copper is 377W/m DEG C, and the heat transfer coefficient of common steel tube is 54 W/m DEG C, it can be seen that the exchange capability of heat of copper pipe is about 67 times of common steel tube.So when being required in fixed space than larger heat exchange amount arrangement, the arrangement of copper pipe is more reasonable.
Description
Technical field
The utility model belongs to boiler technology field, and in particular to a kind of normal-pressure hot-water boiler.
Background technology
Normal pressure fuel oil（Gas）Hot-water boiler is heated using diesel oil or natural gas as fuel by burner to water, realizes heating
With offer life, bathing hot water, boiler intelligent degree is high, heating is fast, low noise, free from dust, is during one kind is especially suitable for
The economical fast-selling boiler kind of state's national conditions.Domestic common normal-pressure hot-water boiler form has two kinds：
1.CLHS vertical boilers use burner underneath type combustion system, fuel pressurized firing in flue, high temperature cigarette
Gas carries out radiation heat transfer in flue, enters back into smoke-fire-tube heat convection, is most discharged afterwards through upper smoke box.
2.CWNS horizontal boilers use the full return structures of wetting back-type three, and flue gas flow is long, in order to reduce exhaust gas temperature, all-wave
Line flue is set, and flame is produced strong disturbance, effectively prevent causes the reduction of equipment life because of metal heat-expansion shrinkage.
The body manufacture of both the above boiler uses pan shell type structure, in normal-pressure hot-water boiler heating system, separately matches somebody with somebody
There are heat exchanger and elevated tank, setting dirt separator and backwater to open and close valve in water return pipeline prevents water hammer, and protection is normal
Press steam generator system.Equipment in conventional atmospheric hot-water boiler heating system is commonly provided with circulating pump, small pump, heat exchanger, decontamination
Device, backwater opens and closes valve, elevated tank etc..If wherein to high-rise heat supply, because normal-pressure boiler is unable to pressure-bearing, then heat exchanger be must
With equipment.Heat exchanger is such as configured, a set of circulating pipe system is just had more, circulating pump and small pump of corresponding secondary network etc. are set
It is standby to be also required to increase.
The content of the invention
The purpose of this utility model is to provide a kind of normal-pressure hot-water boiler with heat exchanger, normal pressure part and heat exchanging part
Split-phase is separated, and has both ensured the normal pressure running status of boiler body, need to be separately with heat exchanger etc. one when can cancel to high-rise heat supply again
The investment of complete equipment, is that user is cost-effective.
The technical solution adopted in the utility model is：Normal-pressure hot-water boiler with heat exchanger includes boiler body and is arranged on
Water tank above and below body of heater, is provided with copper pipe heat exchanger in upper tank.
The utility model is that heat exchanger is carried in boiler body, has broken the structure type of conventional atmospheric boiler, can
Ensure atmospheric pressure state during boiler operatiopn, can ensure certain pressure of supply water when to the heat supply of ordinarily resident building again, make heat supply steady
It is fixed, and eliminate secondary network heat-exchange unit.The heat transfer coefficient of copper is 377W/m DEG C, and the heat transfer coefficient of common steel tube is 54
W/m DEG C, it can be seen that the exchange capability of heat of copper pipe is about 6-7 times of common steel tube.So being required in fixed space than larger
Heat exchange amount arrangement when, the arrangement of copper pipe is more reasonable.
The utility model can be used alone in normal-pressure hot-water boiler built-in heat exchanger structure, and a heat exchanger supplies heating,
Another heat exchanger supplies domestic water；Also two heat exchangers can be connected in a main pipe while for heat supply.Eliminate use
The trouble of heat-exchange unit is separately purchased at family, is that user saves cost of investment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 left view.
Embodiment
Boiler body 2 of the present utility model is upper and lower to be provided with cubic water tank 5,1, and upper tank 5 has expansion tank 4 above.
The copper pipe heat exchanger 3 set in upper tank 5 is U-tube beam of the mouth of pipe outside water tank, and the import of tube bank connects water inlet pipe,
Export connection pipe line.Two copper pipe heat exchangers 3 are set in upper water box 5 simultaneously.Hot water flow in two heat exchangers is not
Together, left side heat exchanger is using two flows, and right side heat exchanger makes the leaving water temperature of two heat exchangers different using four flows,
To arrive different occasions for users to use.As user unify heat supply in use, if connect a main pipe, you can realize two heat exchangers
Mix the effect of heat.Heat exchanger is assembled in factory finish after carry out 0.2MPa the water pressure test, it is ensured that the pressure-bearing of heat exchanger section and
Sealing.This design is divided to normal pressure heated portion and system water outlet heating part to be designed to two independent pipelines mutually exchanged heat.
