Description
Technical field
The present invention relates to gas fired-boiler field, be specifically related to a kind of module furnace waits resistance current-sharing preheating backwater condensing heat
Exchanger.
Background technology
Condensed type combustion gas module furnace is a kind of novel central heating appliance, and its effects of energy conservation and environmental protection is notable, extensively applies
In large-scale occasion central heating, confessions such as Factory Building, office block, Shang Zhu community, hospital, supermarket, hotel, bath center, swimming pools
Hot water.
The furnace interior of above-mentioned gas module stove is provided with several gas modules, and gas module passes through smoke collection pipe and stove
Outlet flue connection above body.When gas module furnaceman makees, fuel combustion produces high temperature heat, also can after main heat exchanger
Discharging 160 DEG C～the high-temperature flue gas of 200 DEG C, high-temperature flue gas is discharged into through air-introduced machine, smoke collection pipe by the fume collecting chamber for heating module
In air.The exhaust gas temperature of conventional boiler is even as high as more than 250 DEG C, generally also can absorb in high-temperature flue gas with retracting device
Part sensible heat, but owing to being limited by retracting device structure and material, exhaust gas temperature all drops less than condensation temperature.It is clear that
Sensible heat in high-temperature flue gas does not make full use of.The more important thing is: the superheated vapour in high-temperature flue gas is when dropping to condensation temperature
Can condense and discharge substantial amounts of latent heat when spending then entirely without utilization, therefore, the thermal efficiency can only achieve 86%～90%.
Certainly, gas module stove can reduce exhaust gas temperature by strengthening the exchange capability of heat of heat exchanger.But the row of being as
The reduction of cigarette temperature, superheated vapour will become acid condensate water at gas module internal condensate.On the one hand, acid condensate water meeting

Time need the air of more than 10 times to mix, and the dust in air can be met humidity hysteresis through inside modules and stayed and pile up, and also can drop
Low efficiency, even can cause hot-spot to burn out module time serious.
Therefore, in order to ensure the normal work and use life-span of gas module, the exhaust temperature of flue gas cannot be below 150
DEG C, which limits the further raising of gas module furnace thermal efficiency.Further, water (the such as natural gas produced during fuel combustion
CH4+2O2=CO2+2H2O) when high temperature discharge, being to be discharged in air with the form of acid superheated vapour equally, this is not only
Also the greenhouse effect of the earth can be aggravated to environment.
For above-mentioned, the distributive pipe that condensing waste-heat recovery device generally uses many groups in parallel carries out heat friendship with high-temperature flue gas
Changing, the latent heat making the sensible heat in high-temperature flue gas and water recovery discharge is utilized, and is used for preheating backwater, reach energy-conservation it
Purpose.But, owing to being limited by waste-heat recovery device volume, each distributive pipe is often difficult to current-sharing, and flow difference causes
Being heated uneven, heat exchanger effectiveness can not give full play to, and the latent heat that sensible heat in high-temperature flue gas and water recovery discharge is not
Can make full use of.
