Description
Technical field
The utility model relates to burnt gas wall hanging furnace components, specifically, being to be related to a kind of improved burnt gas wall hanging furnace heat
Recycle balanced-flue.
Background technique
Balance type gas water heater is current safest gas heater.With straight-line, forced-ventilated two classes water heater phase
Than, the maximum of balance type gas water heater be not both it can be formed together with mating flue one be isolated with room air it is close
Envelope system, i.e., do not consume room air, will not cause smoke pollution.Balance type gas water heater burn required for oxygen be
From outdoor absorption, generated exhaust gas is also that discharge is outdoor, will not thus consume indoor oxygen, not will cause indoor anoxic
Situations such as, therefore, balance type gas water heater may be mounted in toilet or bathroom.The maximum feature of balanced type water heater
It is that gas heater forms the sealing system being isolated with room air together with mating flue.
Flue gas is expelled directly out from the intermediate conduit of balanced-flue in balance type gas water heater, and with certain in flue gas
Heat, be expelled directly out and cause waste, and the outer layer of balanced-flue is air, residence time of the air in outer layer pipe prolong
Air themperature increases in the case where length, after hot-air enters in furnace, can accelerate the kindling and combustion process of combustion gas, guarantee in furnace
Stablize burning, plays a part of improvement, overheavy firing, and how to improve air themperature using the temperature of discharge flue gas institute band becomes
Urgent problem to be solved.
Utility model content
The purpose of this utility model is to solve the deficiency of above-mentioned technology, provides a kind of balanced-flue, utilizes discharge flue gas institute
The temperature of band improves air themperature, guarantees to stablize burning in furnace, improve, overheavy firing.
In order to solve the above technical problems, the utility model provides a kind of improved burnt gas wall hanging furnace heat recovery balance cigarette
Road, including centrally located smokejack and positioned at the annular air air intake duct of smokejack outer layer, on the inner wall of free-air diffuser
Be equipped at intervals with the first barrier wall and the second barrier wall, on the first inner wall of free-air diffuser be equipped with the first barrier wall, air into
Second inner wall of air flue is equipped with the second barrier wall, and the sum of the first barrier wall and the height of the second barrier wall are greater than free-air diffuser
Height, the first barrier wall and the second barrier wall are annular.
Preferably, the second barrier wall is fixedly mounted on the outer wall with smokejack.
Preferably, the distance between the first barrier wall and the second barrier wall are 2-8cm.
Compared with prior art, improved burnt gas wall hanging furnace heat recovery balance flue described in the utility model, reaches
Following effect:
Due to being arranged alternately the first barrier wall and the second barrier wall in free-air diffuser in the application, when air inlet
At S type route air inlet, time of the air in balanced-flue is extended, can use the heat of discharge flue gas institute band to improve sky
Temperature degree guarantees to stablize burning in furnace, improve, overheavy firing.
Since burning is improved and is strengthened in furnace, in addition the hot blast temperature entered in furnace improves, mean temperature water in furnace
It is flat to be also improved, so as to strengthen radiant heat transfer in furnace；
Reduce furnace internal loss, reduces discharge flue-gas temperature, improve fuel wall hanging furnace thermal efficiency.Due to flameholding in furnace,
The reinforcing of radiant heat exchange can reduce loss of the inadequacy burning for chemistry mechanics reason；On the other hand, balanced-flue utilizes fume afterheat, into
One step reduces flue gas loss, and this improves the thermals efficiency of burnt gas wall hanging furnace.
